The working principle of an air conditioner is based on heat transfer from inside air to outside air. This work of exchanging heat is done with the help of air conditioner coils. Two types of coils are used in an air conditioner:
1. Condenser Coil
The condenser coils are placed in the outer part of the air conditioner. These coils are made up of aluminum and cover the air conditioner compressor. A fan is fixed inside the system, which is responsible for moving air across the condenser coils. These types of coils are affected by debris from trees, lawn mowing, and airborne dust.
2. Evaporator Coil
This type of coil is fixed inside the air conditioner at the main duct junction that is above the furnace. These coils are responsible for changing the state of refrigerant from liquid to gas.
The process of air conditioning is based on a state change cycle of refrigerant. The refrigerant is changed to gaseous form by evaporator coils. This gas is then passed through the compressor, which compresses the gas under high pressure. This process increases the temperature of the gas, which is then passed through the condenser coils. The work of the condenser coil is to change the hot gas back into a liquid. This liquid comes back to the evaporator coils, and the cycle repeats again and again.
Coils blocked by dirt and dibris will affect the working cycle. This results in the failure of the compressor and the air conditioner stops working properly. Cleaning the coils in your air conditioner is necessary to increase the service life of compressor and the efficiency of the air conditioner.
Here, we take a look at cleaning solutions for air conditioner coils and fins.
