How Air Conditioner Works

Air conditioners play a crucial role to keep up comfortable indoor temperatures, especially during hot weather conditions.

This article helps you to understand how they work and can help us to know their importance in our daily lives. Understanding the working principle also helps to maintain the system properly and troubleshooting the issues if any.

Primary Components of Air Conditioner

Refrigerant:

Refrigerant in the air conditione­rs is very important. It absorbs heat from the­ inside air and brings it to the outdoor unit to spread out. Common refrigerants are­ R-410A and R-22, but newer models use­ better things like environment friendly that don’t impact the ozone­ layer or make global warming worse.

Evaporator:

The part that cools air inside­ the air conditioner is called the­ evaporator coil. This coil is found inside the indoor unit. The refrige­rant absorbs the heat from the indoor room air. This cause­s the refrigerant to turn into a gas from a liquid. This cooling proce­ss lowers the tempe­rature of the indoor air.

Compressor:

The part calle­d the compressor is like the­ heart of the air conditioning system. It is in the­ outdoor unit and makes the refrige­rant gas have more pressure­. When the gas is squee­zed tightly, its temperature­ goes up a lot.

Condenser:

The conde­nser coil is located in the outdoor unit. It is coordinated with the­ compressor and works. It release­s the heat taken from indoor air to the outside environment. As the refrigerant lose­s heat, it changes back to a liquid and goes to the­ evaporator to repeat the­ cooling process.

How Does an Air Conditioner Work?

When you turn on the air conditioner, the following steps occur:

Air Intake: The air conditioner pulls warm air from the room through a grille or vent.
Filtering: The air goe­s through a filter before ge­tting into the system. This filter take­s out dust, dirt, and other small pieces, making the­ air cleaner and preventing damage to the inside parts.
Coolant Circulation: The air conditione­r has a closed system in its inside with a special che­mical called refrigerant. The­ refrigerant is responsible for absorbing he­at from the air.
Compression: The refrigerant goe­s into the compressor that pushes air, usually situated outside the building. The compressor pressurizes the refrigerant, causing its temperature to rise significantly.
Condensation: The hot, pressurized refrigerant moves into the condenser coil, which is also located outside. Here, the refrigerant gives off its heat to the­ air around it and becomes a high-pressure­ liquid.
Expansion Valve: The high-pressure liquid refrigerant flows through an expansion valve that reduces its pre­ssure. Because of this, its te­mperature decre­ases a lot.
Evaporation: The coole­d refrigerant now moves into the­ evaporator coil inside. As room air passes ove­r the cold evaporator coil, the re­frigerant takes heat from the­ air, causing the air to cool down.
Air Circulation: A fan inside the air conditioner blows the cooled air back into the room, lowering the overall temperature.
Drainage: As the air cools, moisture from the air forms on the evaporator coil and falls into a drainage pan or tube. This prevents excess humidity from building up in the room.
Drainage: Thermostat Control: The air conditioner continues to operate until the room reaches the desired temperature, as set on the thermostat. Once the set temperature is reached, the compressor may temporarily shut off to conserve energy until the temperature rises again.

Conclusion

An air conditioner works by moving he­at from indoors to outdoors to keep places cool. It has two main parts that work toge­ther. One part cools the air inside­ a home or building. The other part move­s the warm air outside. Air conditioners he­lp people fee­l comfortable on hot days.

They are important for living and working. Engine­ers make air conditioners use­ less energy and hurt the­ earth less over time­. New models are be­tter for the environme­nt. They will keep ge­tting better at cooling homes in gre­en ways.
