Best AC 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 functioning whereas the AC needs the windows to be shut. Having begun on a lighter note, we shall dig deep and look at the various aspects that you should understand while installing air conditioners in your homes and offices.
Working of the air conditioner
There are two explanations for the working of the air conditioner. One is the scientific explanation whereas the other one is a simpler one that could be understood by all. We shall begin with the simpler one.
Heat and cold are synonymous with each other. The absence of heat is cold and vice versa. The AC works on a similar principle. It removes the heat from inside the rooms. Thus, you experience the rooms getting cooler.
Does this not bust one of the biggest myths that air conditioners generate cooling? No, they do not do that. They eliminate the heat thereby cooling the rooms
We now come to the scientific explanation of how Ac units work. Basically, the air conditioner works on the three principles of evaporation, condensation, and compression. We shall look into these processes in brief to get a fair idea.
You have different kinds of AC units. In a single-unit window AC, the compressor, condenser, and the evaporator are located in a single unit. In case of a split AC unit, you have the compressor and the condenser situated in the outdoor unit whereas the indoor unit comprises of the evaporator coils.
Size of the AC – Select the right Tonnage
Various factors go into the selection of the right size of the AC. Let us look at all of them in brief.
What is the concept of tonnage of the AC?
As you browse your way through the AC units in the market, you find the air conditioners of different tonnage such as 1-ton, 1.5-ton, 2-ton, and so on.
What does this imply?
The tonnage is the amount of heat the air conditioner removes from the room in one hour. The mathematical unit for tonnage is BTU (British Thermal Units). 1 ton equals 12000 BTU. Higher the BTU, the greater is the cooling effect.
We have just seen that the size/tonnage of the AC depends on various factors. You can also add a couple of other relative 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 conditioning unit consume? This is a common question on the minds of all AC buyers. It again depends on various factors like the tonnage, star rating, and usage of the AC and so on. Let us look at some of the principal aspects in brief.
Modes of operation of the AC units
There are various modes in which you can use the AC. The consumption of electricity depends on the mode of operation of the AC.
You have just seen the various working modes of an AC. Choosing the right mode for your AC can go a long way in reducing your electricity consumption.
We shall also look at some other aspects that affect electricity consumption.
The principal job of the air conditioner is to remove the heat from the room thereby making it cool. Hence, a lot depends on the size of the room. Understand that the electricity consumption of an AC unit depends on the amount of heat present in the room.
A 1.5-ton AC in a room measuring 120 sq feet will work differently as compared to the same AC in a room measuring 150 sq feet. This is because of the greater volume of hot air.
Some places in India like Delhi or Nagpur become very hot in the summer months. However, the climate remains dry. On the other hand, places like Mumbai and Chennai experience a great deal of humidity. It might not be hot but the humidity can be a draining experience. Your AC will work differently under both circumstances.
The former case requires the AC to cool down the rooms whereas the principal job of the AC in the latter instance is to remove the humidity. Thus, an AC with a larger size and tonnage is perfect for the hot places whereas a smaller AC unit would suffice to remove the humidity.
This is a surprising factor, but colours do affect the performance of the AC. Darker colours absorb more heat. Hence, they take a longer time to cool. Hence, it is always better to have lighter coloured walls and curtains.
The more the number of people in the room, the higher is the emission of heat from the bodies. Hence, you experience that you require AC units of higher tonnage to cool rooms having a higher number of people. A 150 sq feet room in your house can work with a 1.5-ton AC whereas the room of the same size will need two 2-ton ACs in case you run a coaching class/school with say 20 to 25 kids in the room.
Just as people emit heat, so also do electrical and electronic appliances. The simple appliances like bulbs emit heat. Hence, it is beneficial to have LED lights in your room. They not only save electricity but also emit less heat.
Having a lot of furniture in the room can also increase the electrical consumption of the AC. It is better to keep your cupboards and shelves closed in an AC room. The walls absorb heat as well. Hence, insulating the walls can also help in reducing electrical consumption.
Inverter AC – Concept, Working, and Benefits
The most common term doing the rounds today is ‘Inverter AC’. What is an inverter AC? If you think that this is an AC unit that can work on the home inverters, I am afraid, you are sadly mistaken. The home inverters have nothing to do with inverter AC. These AC units work on the Inverter Technology whereby they save a lot of power.
This is not the case with inverter ACs. These compressors work at variable speeds. In this technology, the compressor never switches off. It is always on. But, it runs at varying speeds thereby drawing less power.
It is more or less like the functioning of the accelerator in a car. As you increase the speed, you press on the accelerator. In case you want to slow down, removing the foot from the accelerator pedal is enough. The vehicle starts cruising without consuming any fuel. Thus, inverter technology is a power-saving feature available only in the split AC models.
The benefit of using inverter AC units is that they are highly energy efficient. A 3-star inverter AC is equivalent to the 5-star normal split AC. This explains the efficiency of the inverter AC vis-à-vis the non-inverter ACs.
Inverter AC vs Non-Inverter AC
We shall see the difference between the efficiency of an inverter AC and the non-inverter AC.
The basic difference between the inverter AC and the non-inverter AC is that the former is capable of running at variable speed and variable tonnage. The non-inverter AC units run at a constant speed and tonnage.
Inverter AC units are capable of adjusting their speed and tonnage according to the heat inside the room. The non-inverter AC units do not have this capacity.
Efficiency wise, inverter AC units are 7% more efficient than their counterparts in the same star rating category.
Do you have the ideal setting in your room at all times? No, the numbers of people vary and so does the temperature levels. Hence, you need an AC unit that is capable of adjusting to the ambience in the room. The inverter AC units are capable in this regard.
We reproduce the BEE data of 2018 about power consumption of various AC units if different tonnage and ratings. This data assumes total consumption for 1600 hours.
This table shows that higher the star rating, the lower is the consumption. It also indicates that the inverter AC units are extremely energy efficient.
Copper Coil vs Aluminium Coil
We shall throw some light on the various aspects of choosing the right kind of coils for your AC.
On the subject of corrosion, one must add that there are technologies available today that work towards reducing corrosion. One such technology is Blue Fin Condenser. In this technology, they paint these coils with anti-corrosive materials thereby increasing the overall life of the AC units.
In fact, you find the microchannel condenser coils to be aluminium coils. They are flat aluminium tubes having minute holes in them through which the refrigerant flows. Since the entire set up is of a single metal, aluminium, there is no question of galvanic corrosion. Hence, these coils are a good option for ACs working in coastal regions. Samsung uses this technology in its AC and calls it the MultiJet technology.
Reciprocating Vs Rotary Compressors
You have seen the difference between aluminium and copper coils. Now we shall shirt our attention towards compressors. Let us now look at the difference between the reciprocating and rotary compressors.
Anyone will say that the compressor is the most important component of any AC unit. In fact, it is the heart of the unit. Hence, one should have knowledge of how compressors work. Let us see the role of the compressor in an AC.
There are two major types of compressors in use in the AC units.
Reciprocating compressor – This is similar to the engine of the automobile that works on the concept of the cylinder and piston. The piston works in a back and forth motion resulting in compression and release of the gas.
Rotary compressor – This arrangement consists of a number of rotors having very little clearance between them. These rotors rotate in opposite directions whereby the air passing through them emerges at a higher pressure.
Let us look at the pros and cons of the reciprocating and rotary compressors to understand which of the technologies is better.
Reciprocating Compressors Pros
- Easy to maintain
- Capable of working at higher pressures
Reciprocating Compressors Cons
- Produces a lot of noise
- The air comes out at a high temperature
Rotary Compressors Pros
- Good for large offices and industries
- Less noise
- Air comes out at a lower temperature
Rotary Compressors Cons
- Expensive as compared to reciprocating compressors
- Higher usage is required for optimum working
One can conclude from the above pros and cons that the reciprocating compressors are perfect for homes and small offices. The rotary compressors are ideal for heavy-duty uses such as in offices and industries.
Air conditioning Refrigerants
Normally, when you find that the AC does not deliver enough cooling, the mechanic suggests that you replace the coolant. What exactly is this coolant or the gas as they call it in many parts of the world?
|Refrigerant||Global Warming Poetential||Ozone Depletion Potential|
Various types of refrigerants have been in use over the years. They are as follows.
One should have awareness about these minute factors while deciding to purchase AC units for your house. Every person in the world has a duty towards maintaining the sanctity of the environment. You need to leave a better world for your children to live in. Small things such as choosing the right coolant for your AC and refrigerator can play a big part in this endeavour.
Star Ratings, EER, CoP, ISEER
Let us now look at the factors affecting the efficiency of the AC units and the concept of star ratings.
Energy Efficiency Ratio: (EER)
Co-efficient of Performance: (CoP)
Whenever you venture to buy an AC, the first thing you normally look out for the star ratings. What exactly are the star ratings? The Bureau of Energy Efficiency, Department of Energy Savings Government of India prescribes these star ratings for various electronic products. A lot of factors go into the formulation process.
These ratings are fixed for specific periods. We furnish below the star ratings for window and split AC units for the period 01.12.2016 to 31.12.2017.
This table suggests that you should look at the star ratings along with the EER. It is mandatory on the part of AC manufacturers to include the EER on the star rating sticker. Understand that the 5-star AC is always going to be more expensive than the 4-star AC. However, you do save a lot in energy consumption over a long period.
There are other aspects to look into while we are on the topic of energy savings. They include the SEER, ISEER, and other terms concerned with the performance of the AC such as CSTL and CSEC. We shall look at all these terms in brief for the sake of better understanding of the subject.
Now, we come to the concept of ISEER.
ISEER = CSTL/CSEC (Total amount of heat removed to the total amount of energy consumed)
The BEE makes it mandatory for Indian AC manufacturers to declare the ISEER on the star rating label. Here is the defined range of ISEER for Inverter ACs (We shall discuss the inverter ACs in the article subsequently).
While on the subject of star ratings, you should be aware of certain terms and concepts regarding your AC units. You will come across these terms frequently. It is better to be aware of the same and ask questions to the dealer before deciding on the type of AC you wish to buy for your home.
Rated Cooling Capacity: The rated cooling capacity of an AC is ‘a ton’. This is equal to 12000 BTU per hour.
The maximum cooling capacity is again measured in tons. For example, a 2-ton AC will remove 24000 BTU of heat per hour from the room. The requirement for the room can vary depending on various factors discussed earlier. It is advisable not to oversize the AC because it can affect the performance of the AC.
You find this figure on the star rating label. It is mandatory on the part of AC manufacturers to include this figure. This is equivalent to the power consumption in Watts when the AC runs at 100% load. A 1.5-ton AC will consume about 1500 w/hr. Hence, you can see that the AC will consume around 1.5 to 2 units per hour.
However, if you use the AC continuously for say 5 hours, the consumption is not 1.5 or 2 times 5. This is because the compressor switches off and on at regular intervals. Therefore, the consumption of 5 hours will definitely be less.
By applying the above concept, the half power input is the power consumption in Watts when the AC runs at 50% of the load.
This is the power consumptions when the AC runs at its maximum tonnage capacity. This figure will differ from the Rated Power Input because of the tolerance of + or – 5% allowed by the BEE. Even a 1.2 ton AC is marketed as 1 ton.
Now, you have seen the various factors that affect the electricity consumption of the air conditioning units.
Best Air Conditioner – Frequently Asked Questions
It is natural for people to have doubts. In a way, it is better to clear these doubts before investing in the AC unit. You will not regret the investment if you have complete awareness of the concepts of air conditioning. We now come to the final part of our comprehensive AC buying guide as we address the common concerns of prospective AC buyers and users.
1. Which AC brand is the best?
There are innumerable AC brands available on the market. It is a tough task to choose the best among them. This guide will give you an idea of the aspects you have to look into while buying AC units. Energy efficiency is one. Environmental friendliness is another. You have to look at the cost factor as well.
Considering all the three major aspects, it is always better to go for inverter AC units. You have various companies that are specialists in the manufacture of AC equipment. The first names that come to mind are Carrier, Blue Star, Daikin, etc.
Secondly, you have companies that manufacture various electronic appliances other than AC units. The most prominent among them are Hitachi, Mitsubishi, LG, Voltas, etc. You have the local India brands like Onida and Godrej that manufacture ACs to suit Indian conditions. All these brands are reputed brands. You can go for the one that offers the maximum benefits at the minimum cost.
2. Which AC brand provides the best service?
It is better to check out beforehand as to whether the AC manufacturing company has provisions for servicing your AC in your city. Transporting it to another city is not a feasible job.
Usually, the reputed manufacturers like Carrier and Daikin have arrangements with local service centres. The Indian make AC units do not face this problem. It is better to read customer reviews before going for the right AC brand. The reputed AC brands mentioned above have such facilities. Nevertheless, check it out before you invest in the particular brand.
3. Is it safe to buy AC online?
Yes, it is. You have reputed websites like Amazon where you can order the best AC units at great discounted rates. There is absolutely no harm in buying AC units online, especially from the reputed eCommerce platforms.
4. is it OK to opt for AC with aluminium condenser?
The most common metals used for manufacturing condenser tubes are copper and aluminium. Both these metals have their advantages and disadvantages.
Copper has a high heat transfer coefficient as compared to aluminium. At the same time, aluminium is extremely malleable and comparatively inexpensive. But, they require higher maintenance. Therefore, you can opt for AC with aluminium condensers though copper is the preferred choice all over the world. Aluminium condensers are not bad either.
5. What is Blue Fin / Gold Fin technology?
Corrosion is the biggest enemy of these air conditioning units. Over a period, the condenser tubes suffer from corrosion thereby requiring replacement and repairs.
To overcome this problem, manufacturers use Blue Fin or Gold Fin technology whereby they paint the condenser tubes with special anti-corrosive paint. This improves the life of the AC unit. The only difference between Blue Fin and Gold Fin technology is that Gold Fin technology does not rust easily thereby increasing the life expectancy of the AC. However, this technology is expensive as compared to Blue Fin.
Both these technologies have their merits and demerits. It is up to the consumer to make the choice after considering all aspects.
6. Is stabilizer required for the Air conditioner?
Every AC has a voltage operating limit. You will find this range printed on the AC label. Check out if the area you live in has voltage fluctuations beyond these limits. In case, it is so, you should invest in a stabilizer for your AC to protect it from voltage fluctuations.
It is better to be safe than to be sorry. A stabilizer will not cost much when compared to your AC. Install one and do not worry about voltage fluctuations.
7. Which condenser is better for coastal areas?
Corrosion is the main problem that condensers face. Copper is an excellent metal for manufacturing condenser coils. But, copper is also unique for being the only metal to fall prey to formicary 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 find this type of corrosion in coastal areas where there is a lot of humidity in the environment.
Usually, you see AC units having copper coils and aluminium fins. Such units suffer from galvanic corrosion. Hence, it is better to have a single metal for the condenser tubes as well as the fins. The microchannel condenser coils are the best for use in coastal regions. Samsung uses this technology in the manufacture of condenser coils.
The major AC manufacturers use Blue Fin and Gold Fin technology for coating the condenser coils.
8. What is Air Purifier, dust, bacterial filters in AC?
Indoor air has a lot of dust. This dust and bacteria can cause respiratory problems. In the normal circumstances when you do not use the AC, you keep the doors and windows of the room open.
This ensures circulation of the air. But, when you operate the AC, you have to close the windows and doors. This entails that you inhale the same air. The AC units have dust and bacterial filters that trap these ingredients from recirculation.
The modern-day AC units come with air purifiers as well. This ensures that you have pure and clean 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 humidity. Running the AC in normal mode entails that you circulate the humidified air through the machine. This is why you have the dehumidifier mode in the AC.
This is also known as a Dry mode where the AC removes the excess humidity from the room without any significant change in the temperature. Hence, people living in areas near the coast should go for ACs with dehumidifiers. They add to the comfort value of the AC.
10. What is a dual inverter AC?
You find this Dual inverter compressor in certain brands of LC AC units. The very name suggests that you have double the efficiency that you experience in a single inverter AC. This technology ensures that the AC functions with less noise and cools faster as well. When it cools faster, it entails that the compressors function at low speeds most of the time. Hence, you save a lot in your electricity consumption.
11. What is Mosquito Away technology?
The Mosquito Away technology is present in the latest brand of LG AC units. This technology is based on ultrasonic sound to keep away mosquitoes. The AC units emit this sound that is beyond the hearing power of humans. But, it can discourage mosquitoes. LG uses this technology in their phones, washing machines, and televisions as well.
