The coils in a window air conditioner are located on both the indoor and outdoor units of the system. The coils play a crucial role in the air conditioning process, as they facilitate the transfer of heat and enable the cooling of indoor air.
Indoor Coil (Evaporator Coil): The indoor coil, also known as the evaporator coil, is located inside the air conditioner unit, typically facing the interior of the room. It is responsible for absorbing heat from the indoor air and cooling it down. When the air conditioner is turned on, a fan blows warm indoor air over the cold evaporator coil. As the air passes over the coil, the heat is transferred from the air to the refrigerant inside the coil, causing the refrigerant to evaporate and turn into a gas.
Outdoor Coil (Condenser Coil): The outdoor coil, also known as the condenser coil, is located on the outside of the window air conditioner, typically facing the exterior of the building. The condenser coil is responsible for releasing the heat absorbed from the indoor air. As the refrigerant gas travels from the indoor unit to the outdoor unit, it is compressed, which increases its temperature. This hot refrigerant is then passed through the outdoor condenser coil, where the heat is released to the outside air. The refrigerant condenses back into a liquid state, ready to repeat the cooling cycle.
In summary, the coils in a window air conditioner are divided into two parts: the indoor evaporator coil, which cools down the indoor air, and the outdoor condenser coil, which releases the heat absorbed from the indoor air to the outside environment. These two coils work together to provide the cooling effect in a window air conditioner.
