Best Air Conditioner in India 2020 – Buying Guide

What is the difference between a computer and an air conditioner? The computer requires Windows to be open to function effectively while the air conditioner needs to close the windows. After we started on a lighter note, we will dig deeper and consider the different aspects that you need to understand while installing air conditioners in your home and office.

With the increase in demand for air conditioning units, you have more brands of air conditioners in the market. It also increased levels of awareness among people. But, nevertheless, you should be aware of several features before investing in the right air conditioner for your home. This buying guide aims to make things easy for you.

Conditioning work

There are two explanations for the conditioning work. One is the scientific explanation while the other is the simpler that everyone can understand. We’ll start with the simplest.

Heat and cold are synonymous with each other. The absence of heat is cold and vice versa. Alternating current works on a similar principle. Removes heat from inside rooms. Thus, the rooms feel cooler.

Doesn’t that subvert one of the biggest myths that air conditioners generate cooling? No, they don’t. It eliminates heat and thus cools the rooms

Heatpump

Now we come to the scientific explanation of how AC units work. The air conditioner basically operates on three principles which are evaporation, condensation, and pressure. We’ll look at these processes briefly to get a fair idea.

  1. Each air conditioning unit contains refrigerant (we will talk about this gas later in the article). The first step in making an air conditioner is to compress this refrigerant. When you compress a gas, it turns into a hot, high-pressure liquid.
  2. This hot liquid then flows through the condenser coils where heat is released while the liquid is cooled. But the liquid is still under high pressure.
  3. The expansion valve is driven by converting high-pressure liquid into low-pressure liquid.
  4. This low-pressure liquid flows through the evaporator coils in alternating current. In doing so, it absorbs room temperature. This heat turns the liquid into a gas again. As the heat absorption process continues, you feel the room cool down. Now, you have to make sure not to overheat the room. This explains why you should close the windows. We have talked about this fact in the initial parts of this article.
  5. We are now back to square one. The refrigerant gas returns to its original form. The process keeps repeating constantly.

You have different types of HVAC units. In a single unit window air conditioner, the compressor, condenser, and evaporator are all in one unit. In the case of a separate air conditioning unit, you have the compressor and condenser in the outdoor unit while the indoor unit consists of the evaporator coils.

AC size – select the appropriate load

Various factors go into choosing the right size of an air conditioner. Let’s take a look at all of them briefly.

  1. The city you live in: The climate of the city you live in is important because you need air conditioners with higher capacities when the outdoor temperature rises. For example, summers in Delhi can see temperatures reach 45 ° C, while it will range between 38 and 40 ° C in a city like Chennai at the same time.
  2. The space and size of the room where you install the air conditioner are very important.
  3. The location of the room is vital because a lot depends on the fact that the rooms can get hot if the ceiling gets direct sunlight from the top during the day. The same applies to the sidewalls, too.
  4. The daily use of the air conditioning unit is essential, as is the duration of use in terms of months of the year.

AC-Ton-Split-Inverter

What is the concept of air conditioner load?

As you surf your way through the HVAC units in the market, you find air conditioners with different load capacities such as 1 ton, 1.5 tons, 2 tons, and so on.

What does this mean?

The load is the amount of heat an air conditioner removes from a room in one hour. The payload unit is BTU (British thermal units). 1 ton equals 12,000 British thermal units. The higher the BTU, the greater the cooling effect.

We have just seen that the size/load of the air conditioner depends on various factors. You can also add the other two factors like the number of passengers in the room, the amount of furniture/appliances in the room, etc.

Electricity consumption of air conditioning units:

How much electricity does an air conditioning unit use? This is a common question on the minds of all air conditioner buyers. It again depends on various factors like load, star rating, air conditioner usage, etc. Let’s look at some key aspects briefly.

Methods of operating air conditioning units

There are different modes in which you can use the air conditioner. Electricity consumption depends on how the air conditioner operates.

Energy-saving mode

In this mode, the compressor is turned off when the air temperature reaches the level set in the thermostat. The fan continues running to keep cool. When the temperature exceeds a certain level, the compressor starts up again. The compressor is the largest consumer of electricity. Since it oscillates between on and off modes, it consumes less electricity.

Fast cooling mode

Strictly speaking, this is not an option to save on electricity. But, you have this feature in many AC units where the AC starts working at a specific temperature of 16 or 18 degrees Celsius versus 25 degrees in normal mode.

Sleep mode

This is a special mode in which the air conditioner increases the temperature of the thermostat by one degree every hour until the temperature rises by two degrees. At night, the outdoors is actually cooler. Hence, this facility ensures that your air conditioner consumes less electricity.

Cool mode

This is the default for any conditioner. It depends on temperature and fan speed settings. Ideally, you should keep the temperature set at 25 ° C. This is the most comfortable temperature to ensure maximum efficiency.

Fan mode

In this position, the compressor remains closed. It saves energy in this process but does not cool the room. The ceiling fan can do better.

Dry mode

This is ideal for use in humid climatic conditions like the kind you encounter in places near the sea. The purpose of using this mode is to remove moisture from the air and thus automatically cool the room. The fan operates at lower speeds and the compressor for a shorter duration at larger cycles. The main goal is to remove moisture and not cool the room in this way.

Sixth Sense Cooling

This mode is only available on Whirlpool AC units as the technology adjusts the fan speed according to the temperature inside the room. This is better than the cool mode.

You just saw the different working modes of an air conditioner. Choosing the right air conditioner mode can go a long way in reducing electricity consumption.

We’ll also look at some other aspects that affect electricity consumption.

Room size

The primary function of an air conditioner is to remove heat from the room and thus cool it down. 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 in the room.

A 1.5 ton AC will work differently in a 120 sq ft room compared to the same AC in a 150 sq ft room. This is due to the larger volume of hot air.

Your site

Some places in India like Delhi or Nagpur get very hot in the summer months. However, the climate is still dry. On the other hand, places like Mumbai and Chennai experience a great deal of humidity. It may not be as hot but the humidity can be a draining experience. The air conditioner will work differently in either case.

The first case requires the air conditioner to cool the rooms while the main function of the air conditioner in the last case is to remove moisture. Thus, an AC with a larger volume and load is ideal for hot places while a smaller AC unit is sufficient to remove moisture.

Colors

This is a surprising factor, but colors do affect the air conditioner’s performance. Darker colors absorb more heat. Hence, it takes longer to cool down. Hence, it is always better to have lighter-colored curtains and walls.

The number of people

The more people in a room, the more heat will be emitted from objects. Hence, you feel that you need higher load air conditioning units to cool down rooms with more people. A 150-square-foot room in your home can function with 1.5 tons of air conditioning while a room of the same size will need two 2-ton air conditioners if running a class/training school with 20 to 25 kids in the room.

Electrical appliances

Just as people emit heat, so do electrical and electronic devices. Simple appliances like lamps emit heat. Hence, it helps to have LED lights in your room. Not only does it save electricity, it also emits less heat.

Having a lot of furniture in the room can also increase the electrical current consumption of the air conditioner. It is best to keep cabinets and shelves closed in the A / C room. The walls absorb heat, too. Hence, wall insulation can also help reduce electricity consumption.

Best Air Conditioner – Frequently Asked Questions

1. Which brand of air conditioner is better?

There are countless brands of conditioners available in the market. It is a difficult task to choose the best among them. This guide will give you an idea of ​​the aspects to consider while purchasing an HVAC unit. Energy efficiency one. Environmental friendliness is another thing.

You have to look at the cost factor as well. Considering all three major aspects, it is always best to choose inverter AC units.

2. Which brand of air conditioner offers the best service?

It is best to check beforehand if your air conditioner manufacturer has provisions for air conditioner service in your city. Moving it to another city is not a feasible business. Usually, reputed manufacturers like Carrier and Daikin have arrangements with local service centers.

Indian making HVAC units don’t face this problem. It is best to read customer reviews before searching for the right brand of air conditioner. The reputable AC brands mentioned above have such facilities. However, do check this out before you invest in a particular brand.

3. Is it safe to buy air conditioners online?

Yes, it is. You have popular websites like Amazon where you can order the best air conditioning units at great discount prices. There is absolutely no harm in purchasing HVAC units online, especially from popular e-commerce platforms.

4. Is a stabilizer required for an air conditioner?

Each AC power has an operating voltage limit. You will find this range printed on the AC label. Check if the area you live has voltage fluctuations beyond these limits.

Should this happen, you should invest in an AC balancer to protect it from voltage fluctuations. It’s better to be safe than sorry. The stabilizer device won’t cost much when compared to your conditioner. Install one and don’t worry about voltage fluctuations.

5. Which capacitor is best for coastal areas?

Corrosion is the main problem facing capacitors. Copper is an excellent metal for manufacturing capacitor coils. But copper is also unique in that it is the only metal that falls prey to natural corrosion. This type of corrosion requires the presence of oxygen, water, copper, and organic acid.

The worst part of this erosion is that it is not visible to the naked eye. You find this type of erosion in coastal areas where there is a lot of moisture in the environment. Usually, you see air conditioning units with copper coils and aluminum fins. These units suffer from galvanic corrosion. Hence, it is best to have one metal for the condenser tubes as well as the fins.

Small channel capacitor coils are best for use in coastal areas. Samsung uses this technology to manufacture capacitor coils. Major air conditioner manufacturers use Blue Fin and Gold Fin technology to coat condenser coils.

6. What is the air purifier, dust, bacterial filters in an air conditioner?

The indoor air has a lot of dust. This dust and bacteria can cause respiratory problems. Under normal circumstances, when you are not using the air conditioner, you should keep the room doors and windows open. This ensures air circulation. But when you turn on the air conditioner, you must close the windows and doors. This requires you to breathe in the same air.

Air conditioning units contain dust and bacteria filters that trap these components from recycling. Modern air conditioning units come with air purifiers as well. This ensures that you get fresh, clean air to breathe. You will understand how much dust is in the air when you remove these filters from your air conditioner for cleaning. Imagine how much dust you breathe in.

7. Is it acceptable to choose an air conditioner with an aluminum capacitor?

The most common metals used in the manufacture of condenser tubes are copper and aluminum. Each of these minerals has advantages and disadvantages. Copper has a higher heat transfer coefficient compared to aluminum. At the same time, aluminum is very flexible and relatively inexpensive.

But it requires more maintenance. Therefore, you can choose the air conditioner with aluminum capacitors even though copper is the preferred choice all over the world. Aluminum capacitors aren’t bad either.

8. What is Blue Fin / Gold Fin?

Corrosion is the biggest enemy of these air conditioning units. Over a period of time, the capacitor tubes suffer from corrosion which requires replacement and repair.

To overcome this problem, manufacturers use Blue Fin or Gold Fin technology where they coat the condenser tubes with a special anti-corrosion coating. This improves the life of the HVAC unit. The only difference between Blue Fin and Gold Fin technology is that Gold Fin technology does not rust easily and thus increases the life expectancy of an air conditioner.

However, this technology is quite expensive compared to Blue Fin technology. Each of these technologies has its own advantages and disadvantages. It is up to the consumer to make the decision after considering all aspects.

9. Is a stabilizer required for an air conditioner?

Each AC power has an operating voltage limit. You will find this range printed on the AC label. Check if the area you live has voltage fluctuations beyond these limits.

Should this happen, you should invest in an AC balancer to protect it from voltage fluctuations. It’s better to be safe than sorry. The stabilizer device won’t cost much when compared to your conditioner. Install one and don’t worry about voltage fluctuations.

10. Which capacitor is best for coastal areas?

Imagine how much dust you breathe in.

12. What is a dehumidifier?

In the normal state, the air contains a high percentage of moisture. Normal air conditioner operation requires humidified air to circulate through the machine. This is why I have to put a dehumidifier in my air conditioner.

This is also known as the dry mode as the air conditioner removes excess moisture from the room without any major change in temperature. Hence, people who live in areas near the coast should use air conditioners with dehumidifiers. They add to the comfort value of the air conditioner.

13. What is a double AC inverter?

You find this Dual Inverter Compressor in certain brands of LC AC Units. The very name indicates that you have twice the efficiency encountered in a single AC inverter.

This technology ensures that the air conditioner runs with less noise and cools faster as well. When it cools faster, it necessitates that the compressors operate at lower speeds most of the time. Hence, you save a lot in electricity consumption

14. What is Mosquito Away Technology?

Mosquito Away technology is present in the latest brands of air conditioning units from LG. This technique uses ultrasound to keep mosquitoes away. The AC units emit this sound that is beyond the human hearing ability.

But it can discourage mosquitoes. LG uses this technology in its phones, washing machines, and televisions as well.
