How Air Conditioner Works:

8 Types of Air Conditioner (AC) Did You Know? (2021)

There is a normal process of air cooling inside the AC. Hot air goes inside the AC, which the air conditioner cools and takes it out. This lowers the temperature of the external environment.

Friends, there are some parts in Air Conditioner (AC) that complete the cooling process. There are mainly 4 AC components whose names are as follows –

1. Compressor – This part is in the AC part outside the room. It compresses the air. The hot air taken in by the evaporator goes to the condenser by the compressor.

2. Condenser – This is also on the outside part of the AC. The function of the condenser is to convert hot air into cold air.

3. Evaporator – Its function is to exchange heat. It is a type of coil that takes hot air in and releases cold air into the room.

4. Expansion Valve – It is installed on the Evaporator. Through this, the air goes from one coil to another.

In this, refrigerant Freon gas is used as a coolant.

In the window AC, Evaporator, Compressor, Condenser are all in the same box. Whereas in Split AC, only the Evaporator is in the box inside the room.

How to choose the right Air Conditioner: 

How many tons of AC (Air Conditioner) will be right for you? This question is also important. Because only AC of the right capacity can fulfill your need for cold air. Therefore, the choice of AC should be done carefully. How big is the area to be air-conditioned? According to its answer, the choice of AC is better.

1 ton AC is enough for 2 to 4 people in a normal size room. Whereas for a large hole or more people, an air conditioner of more ton capacity is necessary.

AC is available in tons. Such as 1, 1.5, 3… ton, etc. Ever wondered what is this TON in AC? A ton of AC is its cooling capacity. This capacity is measured per hour. How much air does AC cool in 1 hour? The more tons of AC, the more air it will cool. Normally a 1 ton AC gives cooling equivalent to 1-ton ice.

AC costs 20 BTU in 1 hour to cool 1 square foot of space. 12 thousand BTU is equal to 1 ton. If its math is applied to a room of size 10×10 square feet, then 1 ton of AC is required.

Star rating also comes on AC (Air Conditioner). Like 1, 2, 3, 4…star, etc. This rating tells the power consumption of the AC. The more stars the AC will consume, the less electricity it will consume. The more stars, the higher the cost of AC. This point is also important in the selection of an air conditioner.

Why Is Air Conditioner Capacity Measured in Tons?

What do you think of when you hear the word "ton"? Most people think of how heavy a ton is: 2,000 pounds. But when we are talking about the capacity of an air conditioner, a ton means something completely different. 

A three-ton air conditioner doesn't really weigh three tons – can you imagine installing a 6,000-pound air conditioner in your home? The term "three tons" is actually a phrase for how much an air conditioner can cool a building in an hour.

So, where did that phrase come from? Why do we measure air conditioner capacity in tons? Well, in the 19th century (before the air conditioner was invented), people used huge blocks of ice to cool their homes. 

Ice was harvested from frozen lakes in winter and stored until it was needed in summer. It contains about 12,000 BTU, which is the amount of energy needed to heat one pound of water by one British Thermal Unit (one BTU by one degree Fahrenheit) – needed to melt a ton of ice over the course of 24 hours.

As home-cooling methods changed from old-fashioned ice to more modern air conditioning, such as today's coil models, professionals in the industry continued to measure the amount of heat that an air conditioner could emit from a building. 

Tons can be taken out. So if you have a three-ton air conditioner, and one ton in HVAC parlance is equal to 12,000 BTUs, that air conditioner can remove about 36,000 BTUs of heat from your home in an hour.

FAQ: Frequently Asked Questions

Q. Main parts of an air conditioner.
A. 1 – Evaporator
     2 – Compressor
     3 – Refrigerant
     4 – Condenser
     5 – Expansion Valve

Q. Which gas is used in AC?
A. CFC (Chloro Fluoro Carbon) and HCFC (Hydro Chlorofluorocarbon) were used as refrigerants in Air Conditioner. Earlier only CFC was used which is also called freon gas.

The CFC gas was converted into HCFC (Hydro Chlorofluorocarbon) and began to be used. HCFC It is a better refrigerant than CFC. But it harms the environment more. That is why now HFC (Hydro Fluoro Carbon) is used. Which proves to be better than HCFC. R-401A is the most common HFC.

Q. What should be the temperature of AC?
A. The temperature of AC should be in the range of 25-27 degrees. Which will also reduce the burden on our pockets and will also be good for our health.

Generally, people keep the temperature of AC very low. Between 16 to 20 degrees.

Actually, if we look at our bodies and our environment, this temperature can harm us.

The temperature of the air conditioner should also be different at night than during the day. Because the temperature is lower at night than during the day, we can set more AC settings.

Maintaining the temperature of the air conditioner from 25 to 27 degrees has two benefits. Firstly, it will not have any bad effect on your body. Secondly, our electricity bill will come down.

Q. What to do after installing AC?
A. 1- Get the AC service done once a year.

2 - Get the service of AC done by a good artisan only.

3- The window doors should be opened once a day to avoid the risk of gas leakage.

4- While opening the window and door, the AC should be turned off, it has an effect on the electricity bill.

5- If the gas filling has to be done, then definitely see the quality of the gas.

Q. How many hours should the AC run?
A. We have to maintain the temperature. That is why in our house or room where AC is installed, it should be seen what is the effect of the temperature of the environment.

If we run AC for 24 hours, then our immunity power can be reduced.

If the room is closed for 24 hours, there may be a lack of oxygen there.

In our country, AC is needed only during the summer days. To maintain the temperature during this hot summer, one should walk for a few hours a day.

Q. What to keep in mind before buying AC?
A. Remember any home appliance is a guest of at least 8 to 10 years in our house. If a mistake is made while buying then you can have to suffer for 10 years.

1 - First of all, what is the size of the room where we have to install AC.

2 - For how many people, this air conditioner is going to be used.

3- What is the type of air circulation in the room.

4 - How many electrical appliances are run in the room where AC is to be run.

5 - How much stuff is kept in the room.

Q. Different Between Inverter AC and Non-Inverter AC
A. Both ACs are similar in appearance. It will not be known from the look that this inverter is AC or non-inverter.

The biggest advantage of using Inverter AC is the power consumption. Non-Inverter AC consumes more power as compared to Inverter AC.

In a non-inverter, the compressor runs at a constant speed. Inverter AC runs at variable speed. Here electricity is saved.

A compressor is on-off in a non-inverter. The temperature is uneven. In an inverter AC, the temperature is maintained at the set point.

Instant cooling is available in normal AC. Whereas it takes more time for cooling in inverter AC starters.

Inverter AC has a higher maintenance cost as compared to non-inverter AC.

Compressor warranty in normal AC is 2 to 5 years. Compressor warranty in Inverter AC is 10 years.

R-22 gas is used in normal AC. It pollutes the environment.

R – 32 and R – 410 A are used in inverter AC. This gas does not harm the atmosphere.

Q. Who Invented Air Conditioner (AC)?
A. The modern AC (Air Conditioner) was invented by Wills Haviland Carrier. This modern AC was invented in the year 1902. This Air Conditioner used to run on the power of electricity. He used this AC in a company in Brooklyn city.
