Essential Interview Questions For Air Conditioning Service Technician
1. Explain the working principle of an air conditioner?
An air conditioner works on the principle of refrigeration. It uses a refrigerant, which is a chemical that can easily change from a liquid to a gas and back again. The refrigerant is circulated through a closed system, which includes a compressor, a condenser, an expansion valve, and an evaporator. The compressor compresses the refrigerant gas, which increases its pressure and temperature. The high-pressure gas then flows into the condenser, where it is cooled by the surrounding air and condenses into a liquid. The high-pressure liquid refrigerant then flows into the expansion valve, which reduces its pressure and temperature. The low-pressure liquid refrigerant then flows into the evaporator, where it is heated by the surrounding air and evaporates into a gas. The low-pressure gas refrigerant then flows back into the compressor, and the cycle repeats.
