Best Air Conditioners in India 2019 – Buying Guide

Best Air Conditioners in India 2019 – Buying Guide

What is the difference between a computer and an air conditioner? A computer requires 'Windows' to be open for effective operation, while the CA needs windows to be closed. Having started with a lighter note, we will explore and analyze the various aspects that need to be understood when installing air conditioners in your homes and offices.

Best Air Conditioners in India 2019 – buying guide: With the growing demand for portable ac India units, it has more best air conditioning brand in india of air conditioners on the market. People's awareness levels have also increased. But even so, you need to know several features before investing in the right AC for your homes. This shopping guide aims to make things easier for you.

Working of the air conditioner

There are two explanations for the operation of the air conditioner. One is the scientific explanation, while the other is a simpler explanation that everyone could understand. We will start with the simplest.

Heat and cold are synonymous with each other. The absence of heat is cold and vice versa. The AC works on a similar principle. The heat is removed from inside the rooms. Therefore, discover that the rooms get air cooler in India.

Isn't this one of the biggest myths that air conditioners generate cooling? No, they do not. They eliminate best portable air conditioner with heat by cooling the rooms.

Working of the air conditioner

Now we come to the scientific explanation of how air conditioning units work. Basically, the air conditioner works with the three principles of evaporation, condensation and compression. We will briefly review these processes to get a correct idea.

1. Each air conditioning unit has a refrigerant gas (we will talk about this gas later in the article). The first step in the portable ac India operation is the compression of this refrigerant gas. When it compresses a gas, it becomes a hot liquid at high pressure.

2. This hot liquid flows through the condenser coils where best portable air conditioner with heat escapes as the liquid cools. But the liquid is still under pressure.

3. The expansion valve comes into play when converting the high pressure liquid into a low pressure one.

4. This low pressure liquid flows through the coils of the AC evaporator. In this way, it absorbs the heat of the room. This heat converts the liquid back into gas. As the heat absorption process progresses, the room is cooled. Now, you need to make sure you don't increase the heat in the room. This explains why you should close the windows. We had talked about this in the initial parts of this article.

5. Now we are back to the starting point. The refrigerant gas returns to its original shape. The process continues to repeat itself.

You have different types of air conditioning units. In a single AC unit, the compressor, condenser and evaporator are in a single unit. In the case of a split AC unit, it has the compressor and condenser located in the outdoor unit, while the indoor unit is composed of the evaporator coils.

Size of CA: Select the right Tonnage

Several factors are part of choosing the correct size of the CA. Let's take a look at all of them soon.

Use this AC tonnage calculator to calculate the ton you require for your room.

1. City where you live: the climate of the city you live in is important because you need air conditioning of greater capacity when the outside temperature increases. For example, summers in Delhi can see temperatures reaching 45 degrees Celsius, while at the same time it would be around 38-40 degrees in a city like Chennai.

2. The area and volume of the room where the AC is installed are very important.

3. The location of the room is vital because a lot depends on whether the rooms can be heated if the roof receives direct sunlight from above during the day. The same applies to the side walls.

4. Daily use of the CA unit is essential, as is the duration of use in terms of months during the year.

AC Ton Spli -Inverter

What is the concept of tonnage of the AC?

While browsing through the CA units in the market, you will find air conditioners of different tonnages, such as 1 ton, 1.5 tons, 2 tons, etc.

What does this imply?

The tonnage is the amount of best portable air conditioner with heat that the air conditioner draws from the room in an hour. The mathematical unit for tonnage is BTU (British thermal units). 1 ton equals 12000 BTU. The higher the BTU, the greater the cooling effect.

We have just seen that the size / tonnage of the CA depends on several factors. You can also add a couple of other related factors, such as a number of occupants in the room, the amount of furniture / appliances in the room, etc.

Electricity consumption of the AC units:

How much electricity does an air conditioner consume? This is a common question in the minds of all CA buyers. Again, it depends on several factors, such as tonnage, star rating and the use of CA, and so on. Let's take a brief look at some of the main aspects.

Mode of operation of the AC units.

There are several ways you can use AC. Electricity consumption depends on the operating mode of the CA.

Cool Mode

It is usually the default mode in any AC. It depends on the temperature and the fan speed setting. The ideal is to keep the temperature at 25 degrees Celsius. This is the most comfortable temperature to ensure maximum efficiency.

Fan Mode

In this mode, the compressor remains off. Energy is saved in the process but does not cool the room. A ceiling fan can do a better job.

Dry mode

This is the ideal way to use in humid climatic conditions such as the one experienced in places near the sea. The purpose of using this mode is that it removes moisture from the air, which automatically cools the room. The fan runs at lower speeds and the compressor for a shorter duration in larger cycles. The main goal is to eliminate moisture and not cool the room as such.

Energy saving mode

In this mode, the compressor switches off when the air temperature reaches the level set on the thermostat. The fan continues to work to maintain freshness. When the temperature exceeds a certain level, the compressor starts working again. The compressor is the largest consumer of electricity. Since it oscillates between on and off positions, it consumes less electricity.

Fast cooling mode

Strictly speaking, this is not an option to save electricity. However, it has this function in many AC units where the AC starts operating at a set temperature of 16 or 18 degrees Celsius compared to 25 degrees in normal mode.

Mode of suspension

This is a special mode in which the AC increases the temperature of the thermostat by 1 degree every hour until the temperature increases by 2 degrees. At night, the outside is already cooler. Therefore, this installation ensures that the AC consumes less electricity.

6th cooling direction

This mode is only available in whirlpool central air conditioner units, where the technology adjusts the fan speed based on the temperature inside the best air conditioner for small room. This is better than the cool mode.
You have just seen the different ways of working of an AC. Choosing the right CA mode can be very useful for reducing electricity consumption.

We will also see other aspects that affect electricity consumption.

Room size

The main task of the air conditioner is to remove the heat from the room to cool down. Therefore, much depends on the size of the room. Understand that the electricity consumption of an AC unit depends on the amount of heat in the best air conditioner for small room.

A 1.5-ton AC in a room that measures 120 square feet will work differently than the same CA in a room that measures 150 square feet. This is due to the greater volume of hot air.


Some places in Best Air Conditioners in India like Delhi or Nagpur get very hot in the summer months. However, the climate remains dry. On the other hand, places like Mumbai and Chennai have a lot of humidity. It may not be hot, but humidity can be a grueling experience. The CA will work differently in both circumstances.

The first case requires the CA to cool the rooms, while the main task of the CA in the latter case is to eliminate humidity. Therefore, an AC with a larger size and tonnage is perfect aire air conditioner reviews for hot spots, while a smaller AC unit would be sufficient to remove moisture.


This is a surprising factor, but colors influence the CA's performance. Darker colors absorb more heat. Therefore, they take longer to cool down. Therefore, it is always better to have lighter colored walls and curtains.

Number of person

The more people in the room, the more heat is emitted from the bodies. Therefore, there is a need for higher tonnage AC units to cool rooms that have more people. A room of 150 square feet in the house can operate with a 1.5 tonne AC, while in the same room two 2 tonne CAs will be needed in the case of a coaching / school lesson with about 20-25 children in the best air conditioner for small room.

Electronic appliances

Just as people emit heat, even electrical and electronic devices. Simple devices like bulbs emit heat. Therefore, it is useful to have LED lights in your room. Not only do they save electricity, they also emit less heat.

Having lots of furniture in the room can also increase the energy consumption of the best cheap portable air conditioner. It is best to keep the closets and shelves closed in an best air conditioner for small room. The walls also absorb heat. Therefore, insulating walls can also help reduce electrical consumption.

Inverter AC – Concept, Working, and Benefits

The most common term for making rounds today is "AC Inverter". What is an AC inverter? If you think this is an AC unit that can work for domestic investors, I'm afraid you're very wrong. Domestic investors have nothing to do with the CA investor. These AC units work with Inverter technology, so they save a lot of energy cheap best air conditioners in India.

In a normal AC, the compressor operates at maximum capacity when it is switched on. When the optimum temperature is reached, the compressor switches off and the fan continues to run. When temperatures rise above the threshold limit, the compressor restarts and operates at maximum capacity. This implies that the compressor operates at only two speeds, full and zero.

This is not the case with the AC of the best inverter air conditioner review. These compressors operate at variable speeds. In this technology, the compressor never turns off. It is always on. However, it works at variable speed, so it consumes less energy.

Inverter Air Conditioner

It's more or less like the accelerator running in a cars with best air conditioning in india. As the speed increases, press the accelerator. If you wish to reduce the speed, simply take your foot off the accelerator pedal. The vehicle starts from a cruise without consuming fuel. Therefore, the inverter technology is an energy saving function available only in split AC models.

The advantage of using the AC units of the best inverter air conditioner reviews is that they are highly energy efficient. A 3-star AC inverter is equivalent to the normal 5-star AC division. This explains the inverter's AC efficiency compared to non-inverting ACs.

Inverter AC vs Non-Inverter AC

We will see the difference between the efficiency of an AC inverter and the non-inverter of AC.

The fundamental difference between the AC of the best inverter air conditioner reviews and non-inverting AC is that the former is able to operate at variable speed and variable tonnage. Non-inverting AC units operate at constant speed and tonnage.

The AC units of the inverter are able to regulate their speed and their tonnage based on the heat inside the room. Non-inverting AC units do not have this capability.

In terms of efficiency, the AC drives of the inverter are 7% more efficient than their counterparts in the same star category.

Inverter AC vs Non-Inverter AC

Do you have the ideal configuration in your room at all times? No, the number of people varies and even the temperature levels. Therefore, an AC unit that can adapt to the room environment is required. The AC units of the inverter can do this.

We report the BEE data for 2018 on the energy consumption of several units in alternating current if the tonnage and the classifications are different. This data assumes a total consumption of 1600 hours.

AC units of the inverter bee data

This table shows that the higher the star rating, the lower the consumption. It also indicates that the AC units of the best inverter air conditioner reviews are extremely energy efficient.

Copper Coil vs Aluminium Coil

Copper Coil vs Aluminium Coil

The AC units operate on the basis of compression, condensation and evaporation. This involves moving the refrigerant gas inside the coils in gaseous and liquid form. Now the question arises as to which of the coils is better, copper or aluminum.

In ancient times, the coils were mainly made of copper. Subsequently, General Electronics brought about revolutionary change in 1970, replacing copper coils with aluminum coils. From that day in 1970, the debate between aluminum and copper coils continues.

We will clarify the various aspects of choosing the right type of coils for your CA.

Heat transfer

Copper has a higher heat transfer coefficient than aluminum. Therefore, it proves to be a better heat exchanger than aluminum.

Cost factor

Aluminum is cheaper than copper cheap best air conditioners in india. This is why aluminum air conditioning units are cheaper.


Aluminum is more malleable than copper. Therefore, it is possible to print aluminum in any desired shape more easily than copper. Therefore, aluminum is the preferred choice for producing CA coils.


Now, copper is definitely stronger than aluminum. The bifurcation coils are reputed to last much longer than the aluminum coils. They also need less repairs.


Note that the capacitor coils are always positioned in the external units. Therefore, they are subject to the vagaries of the climate. Copper coils are easier to maintain, while aluminum coils need to be kept in sturdy cabinets, which makes maintenance difficult.


The best cheap portable air conditioner operates in a humid environment at all times. Therefore, there is always the danger of corrosion. This corrosion results in the formation of a layer on the coils, which affects their conductivity. People living in wet areas near the sea should pay close attention to this aspect.

Blue fin condenser technology

Blue Fin Condenser Technology

On the subject of corrosion, it must be added that there are currently available technologies that work to reduce corrosion. One of these technologies is Blue Fin Condenser. In this technology, they paint these coils with anti-corrosive materials, which increase the overall life of the AC units.

Micro-channel capacitor batteries

Microchannel condenser coils

In fact, the microchannel condenser coils are aluminum coils. They are flat aluminum tubes with small holes in which the coolant flows. Since all the configuration is of a single metal, aluminum, it is not galvanic corrosion. Therefore, these coils are a good option for CAs operating in coastal regions. Samsung uses this technology in its CA and calls it MultiJet technology.

Reciprocating Vs Rotary Compressors

You saw the difference between aluminum and copper coils. Now focus our attention on compressors. Now let's see the difference between reciprocating and rotary compressors.

Some will say that the compressor is the most important component of any AC unit. In reality, it is the heart of unity. Therefore, it is necessary to have knowledge of how the compressors work. Let's look at the role of the compressor in a CA.

Top 10 best air conditioners in India: The main task of the compressor is to compress the refrigerant gas at high pressure, converting it into a high pressure liquid at high temperature. This liquid passes through the condenser coils that draw heat from the liquid and release it to the surrounding environment.

However, the pressure is still high. The expansion valve reduces the pressure and converts the liquid into gas which then passes through the evaporator coils. The evaporator coils absorb the heat of the room, which cools the rooms.

There are two main types of compressors used in the AC units.

Reciprocating compressor: it is similar to the cars with best air conditioning in India, that works with the concept of cylinder and piston. The piston operates in a forward and backward motion that causes compression and release of the gas.
Reciprocating compressor

Rotary compressor: this arrangement consists of several rotors that have minimal space between them. These rotors rotate in opposite directions, so the air passing through them emerges at a higher pressure.
Reciprocating compressor

Let's take a look at the pros and cons of reciprocating and rotary compressors to understand which of the technologies is best air conditioners in India.

Reciprocating Compressors Pros
  • Easy to maintain
  • Able to work at higher pressures.
Reciprocating Compressors Cons
  • It produces a lot of noise.
  • The air comes out at high temperature.
Pro rotary compressors
  • Good for large offices and industries
  • Less noise
  • The air comes out at a lower temperature.
Counter rotary compressors
  • Expensive compared to alternative compressors
  • More use is required for optimal work
It can be concluded from the aforementioned advantages and disadvantages that reciprocating compressors are perfect for homes and small offices. Rotary compressors are ideal for heavy use, such as in offices and industries.

Air conditioning refrigerants

Normally, when it is discovered that the AC does not provide sufficient cooling, the mechanic suggests that the refrigerant must be replaced. What exactly is this refrigerant or gas as they call it in many parts of the world?

The refrigerant is also known as a refrigerant and is an important part of air conditioning and refrigeration equipment. The main function of air conditioning refrigerants is to absorb the heat from the room and deliver it outside. Once the heat has been removed from the room, the air in the room is automatically cooled.

The refrigerant is originally in the form of a gas. The compressor cheap best air conditioners in India this gas at high pressure and converts it into a liquid. At such extreme pressures, the liquid has a very high temperature. This liquid passes through the coils of the condenser, where the temperature of the liquid drops considerably but the pressure remains high. When the high pressure cold liquid is released through an expansion valve, the AC units reduce the pressure.

This liquid then travels through the evaporator tubes / coils. This cold liquid absorbs the heat from the rooms and removes it, which makes the air in the room cold. The fans in the AC unit help maintain the temperature.

By absorbing heat, the liquid evaporates and becomes gas once again. The same process is repeated again and again. This is how an AC works. Therefore, you have seen that the refrigerant is the main component of any AC.

Air conditioning refrigerants
Source: Daikin
Different types of refrigerants have been in use over the years. Are the following.

Chlorofluorocarbons - CFC

These were the initial refrigerants used in air conditioning units around the world. They were also known as R12 refrigerants. They were effective, but they played an important role in depleting the ozone layer in the atmosphere. This led to the interruption of the production of this R12 refrigerant. Now, no AC uses this refrigerant anywhere in the world.

Hydrochlorofluorocarbons - HCFC

Environmental concerns have led to the replacement of CFCs with HCFCs. This refrigerant, popularly known as R22, is the most common refrigerant used today in alternating current units in India. However, this refrigerant is not very environmentally friendly. Therefore, there are indications that these refrigerants will be gradually eliminated in the next 4-5 years.

That's why you should be very careful when choosing your AC. If the manual indicates the use of R22 as a refrigerant, it is advisable not to buy that CA because it is obsolete. This is despite the fact that most air conditioning units use this refrigerant in India.

Hydrofluorocarbons - HFC

Compared to R22 refrigerant, HFCs do not exhaust the ozone layer. Therefore, they are relatively environmentally friendly. It has three types of HFCs currently in use (R410A, R32 and R134). The world has advanced and has become a more environmentally friendly refrigerant, hydrocarbons. India is also close to these developing countries and has plans to eliminate hydrofluorocarbons in the coming years.

Hydrocarbons - HC

The search for a more environmentally friendly refrigerant has brought the HC to the world. Air-conditioning companies around the world currently use R290 (propane) and R600A (iso-butane) as refrigerants. It is said to have a zero effect on the ozone layer. Therefore, they are also known as green refrigerants.

The AC inverter uses these types of refrigerants in them. Research is still ongoing in this field to discover the best air conditioners in India refrigerant that respects the environment. Until they find a better refrigerant, R290 and R600A will have a field day.

One should be aware of these minimal factors when deciding to buy air conditioning units for their home. Every person in the world has the duty to maintain the sanctity of the environment. You have to leave a better world where your children can live. Little things, like choosing the right refrigerant for the best cheap portable air conditioner and the refrigerator, can play an important role in this effort.

Star Ratings, EER, CoP, ISEER

Let's take a look at the factors that influence the efficiency of CA units and the concept of star rating.

Energy efficiency index: (EER)

The EER is a very important proportion that distinguishes between CA units. Scientifically, EER = Amount of heat removed per hour divided by the amount of energy consumed.
Therefore, EER = BTU / h / Watt

The higher the EER, the better the performance because the air conditioner removes more heat per hour per unit of energy consumed. Therefore, it is possible to deduce that an air conditioner dryer with a higher EER is more efficient.

Coefficient of performance: (CoP)

You have to do some simple mathematical calculations to get to the CoP. To understand the concept of CoP, you need to know the relationship between BTU and KW hr. best inverter air conditioners in India.
1 KW now = 3412 BTU. Alternatively, you can say that 1 KW = 3412 BTU / hour.

Therefore, 1 W = 3.412 BTU / h

Now, CoP is the amount of heat removed from the air conditioning in watts divided by the power consumption in watts. Therefore, CoP has no units. The higher the CoP, the greater the efficiency of the air conditioner dryer. Let's look at the relationship between EER and CoP.

EER = 3.412 X CoP

Star rating

Whenever you venture to buy an AC, the first thing you need is star rating. What exactly are star ratings? The Office of Energy Efficiency, Department of Energy Savings of the Indian government prescribes these star ratings for various electronic products. Many factors enter the formulation process.

These ratings are fixed for specific periods. We provide below the star classifications for alternating current and divisional units for the period from 01.12.2016 to 31.12.2017.

Star rating

This table suggests that you should look at star ratings with EER. For CA manufacturers it is mandatory to include the EER on the star rating label. Understand that 5-star AC will always be more expensive than 4-star AC. However, best inverter air conditioners in India it saves a lot on energy consumption over a long period.

There are other aspects to consider while we are on the subject of energy saving. They include the SEER, ISEER and other terms relating to the performance of the CA, such as CSTL and CSEC. Let's briefly see all these terms for a better understanding of the subject.

Seasonal energy efficiency report (SEER)

Among the various factors that influence the performance of the AC is the external and internal temperature. In the event that the outside temperature of the house is higher, the air conditioning consumes more electricity to cool the interior.

Temperatures in the rainy season and winters are much lower than those obtained during the summer season. Therefore, the EER of the CA varies according to the season in which the device is used. This is the concept of SEER.

India seasonal energy efficiency report (ISEER)

The concept of SEER and ISEER is the same. However, you should consider two additional factors as shown below.

Seasonal cooling energy consumption (CSEC): total energy consumed by the AC in active mode

Total load seasonal cooling (CSTL): total polymerization eliminated by the AC in active mode air conditioner lowest price.

Now, let's get to the concept of ISEER.

ISEER = CSTL / CSEC (total amount of heat extracted for the total amount of energy consumed)

The BEE makes it mandatory for Indian CA producers to declare ISEER on the star rating label. Here is the ISEER range defined for the CA investor (we'll talk about the investors' CAs in the article below).

While you are on the subject of star ratings, you need to know some terms and concepts related to your CA units. You will find these terms frequently. It is better to know the same thing and ask the dealer questions before deciding which type of CA you want to buy for your home.

Rated cooling capacity: the nominal cooling capacity of a CA is "one ton". This is 12000 BTU per hour.

Maximum cooling capacity

The maximum cooling capacity is measured again in tons. For example, a 2-ton AC will remove 24,000 BTUs of heat per hour from the room. The room requirement may vary based on the various factors mentioned above. It is recommended not to oversize the CA because it could affect the CA's performance.

Rated power consumption

Find this figure on the star rating label. It is mandatory for CA manufacturers to include this figure. This is equivalent to the power consumption in watts when the AC works with a 100% load. A 1.5 tonne AC consumes about 1500 w / h. Therefore, it is possible to see that the AC will consume about 1.5-2 units per hour.

However, if the AC is used continuously for about 5 hours, the consumption is not 1.5 or 2 times 5. This is because the compressor is switched off and switched on at regular intervals. Therefore, the consumption of 5 hours will certainly be lower.

Average absorbed power

When applying the previous concept, the half power input is the power consumption in watts when the AC is running at 50% of the load.

Maximum absorbed power

This is energy consumption when the AC is operating at maximum tonnage capacity. This figure will be different from the nominal input power due to the + or - 5% tolerance allowed by the EE. Even an AC of 1.2 tonnes is marketed as 1 ton.

Now you have seen the various factors that influence the electricity consumption of the air conditioning units.

Best Air Conditioner - Frequently asked questions

It is natural that people have doubts. In a sense, it is better to clear up these doubts before investing in the CA unit. You will not regret the investment if you have a complete understanding of the concepts of air conditioning.

The first names that come to mind are: Carrier, Blue Star, Daikin, etc. Secondly, it has companies that produce various electronic devices other than CA units. The most important of them are Hitachi, Mitsubishi, LG, Voltas, etc.

You have the local good air conditioner brands of India like Onida and Godrej that produce AC to adapt to the conditions of India. All these air conditioner top Chinese air conditioner brands are reliable best air conditioning brand in India. You can choose the one that offers maximum benefits at the lowest cost.

2. Which CA brand offers the best service?

It is best air conditioners in india 2019 to check in advance if the CA company has provisions for the CA service in your city. Transporting it to another city is not a feasible job. In general, renowned manufacturers like Carrier and Daikin have agreements with local service centers.

The Indian makes the air conditioning units do not address this problem. It is best air conditioners in india 2019 to read customer comments before choosing the correct CA mark. The renowned AC Chinese air conditioner brands mentioned above have such services. However, take a look before investing in a particular good air conditioner brands.

3. Is it safe to buy AC online?

Yes it is. You have reputed websites like Amazon, Flip-kart, where you can order the best CA units with excellent discount rates. Online marketing has become an imperative to the success of any business venture best online shopping for air conditioners in India, USA.

Other people are switching to best online shopping for air conditioners in India. There is absolutely no damage in buying CA units online, especially from reliable e-commerce platforms. You can also buy it directly from the company website.

4. Is it OK to choose AC with aluminum condenser?

The most common metals used to manufacture the condenser tubes are copper and aluminum. These two metals have their advantages and disadvantages. Copper has a high heat transmission coefficient compared to aluminum. At the same time, aluminum is extremely malleable and relatively inexpensive. But they require more maintenance

Therefore, it is possible to choose AC with aluminum capacitors, although copper is the preferred option worldwide. Even aluminum capacitors are not bad.

5. What is the Blue Fin / Gold Fin technology?

Corrosion is the biggest enemy of these air conditioning units. During a period, the condenser tubes suffer corrosion, so they must be replaced and repaired. To overcome this problem, manufacturers use Blue Fin or Gold Fin technology, then paint the condenser tubes with a special anti corrosive paint. This improves the life of the air conditioner.

The only difference between Blue Fin technology and Gold Fin technology is that Gold Fin technology does not rust easily, which increases the life of the AC. However, this technology is expensive compared to Blue Fin. Both technologies have their advantages and disadvantages. It is up to the consumer to make the choice after considering all aspects.

6. Do I need the air conditioning stabilizer?

Each AC has a voltage performance limit. You will find this range printed on the AC label. Check if the area you live in has voltage fluctuations beyond these limits. If so, you should invest in a stabilizer for your AC to protect it from voltage fluctuations. It is better to be safe than to complain.

A stabilizer will not cost much compared to its AC. Install one and don't worry about voltage fluctuations.

7. Which condenser is the best for coastal areas?

Corrosion is the main problem faced by capacitors. Copper is an excellent metal for the production of capacitor coils. However, copper is also unique because it is the only metal that has been subject to material corrosion. This type of corrosion requires the presence of oxygen, water, copper and an organic acid. The worst part of this corrosion is that it is invisible to the naked eye. You will find this type of corrosion in coastal areas where there is a lot of humidity in the environment.

Typically, AC units are displayed with copper coils and aluminum fins. These units suffer from galvanic corrosion. Therefore, it is better to have a single metal for the condenser tubes and the fins. Micro channel condenser coils are the best air conditioners in India 2019 for use in coastal regions. Samsung uses this technology in the production of capacitor coils. The main CA manufacturers use Blue Fin and Gold Fin technology to coat condenser coils.

8. What is the air purifier, dust, bacterial filters in AC?

Indoor air has a lot of dust. This dust and bacteria can cause respiratory problems. Under normal circumstances when not using the air conditioner, keep the doors and windows of the room open. This ensures air circulation. But when using the air conditioner, it is necessary to close the windows and doors. This implies that we inhale the same air.

AC units have dust filters and bacteria that trap these circulation ingredients. Today's air conditioning units are also equipped with air purifiers. This ensures that you have clean and pure air to breathe. You will understand the amount of dust in the air when you remove these filters from the AC for cleaning. Imagine the amount of dust you inhale in the normal course.

9. What is a dehumidifier?

In the normal course, the air contains a lot of moisture. The operation of the AC in normal mode implies that the humidified air circulates through the machine. This is why you have the dehumidifier mode in the CA. This is also known as Dry mode where the AC removes excess moisture from the room without a significant change in temperature.

Therefore, people living in areas near the coast should go to the AC with dehumidifiers. They add to the comfort value of the CA.

10. What is a double AC inverter?

You will find this dual inverter compressor in some brands of AC AC. The same name suggests that it has twice the efficiency experienced in a single AC inverter. This technology ensures that the AC works with less noise and cools faster. When it cools faster, it means the compressors run at low speeds most of the time. Therefore, much is saved on electricity consumption.

11. What is Mosquito Away technology?

Mosquito Away technology is present in the latest LG AC unit brand. This technology is based on ultrasonic sound to keep away mosquitoes. The CA units emit this sound beyond the hearing power of humans. But it can discourage mosquitoes. LG uses this technology in their phones, washing machines and televisions.
