How Does an Air Conditioner Work?
An air conditioner works by removing heat and humidity from the indoor air and releasing it outside, leaving the air inside your room cool and comfortable. It uses a refrigeration cycle, much like a refrigerator, but designed for larger spaces.
🧊 Basic Working Process:
Warm Air Intake:
The air conditioner pulls warm air from the room using a fan.
Cooling the Air:
This warm air passes over evaporator coils (located in the indoor unit), which are filled with a cold refrigerant gas.
The refrigerant absorbs the heat from the air, causing the air to cool.
Heat Transfer:
The now heated refrigerant gas is sent to the compressor in the outdoor unit.
The compressor pressurises the gas, making it even hotter.
It is then passed to the condenser coils, where the heat is released into the outside air.
Refrigerant Re-cooling:
The refrigerant cools down and becomes a liquid again, ready to return to the evaporator coils and repeat the cycle.
Cool Air Output:
Meanwhile, the cooled air is blown back into the room by a fan.
🔁 Main Components Involved:
Evaporator Coil – Absorbs heat from room air
Compressor – Increases pressure of refrigerant
Condenser Coil – Releases heat outdoors
Expansion Valve – Regulates refrigerant flow
Refrigerant – The cooling fluid that circulates the system
🌬️ Other Features:
Dehumidification: Removes moisture from the air
Filtration: Captures dust and pollutants
Thermostat: Maintains desired temperature automatically
This cycle runs continuously until the set temperature on the thermostat is reached, ensuring consistent cooling and comfort.
