Most of us know that air conditioner reduces the temperature of the room as per our requirements. But we don’t know exactly it works. Actually, when you turn on the air conditioner, it takes air present in the room and passes it through evaporator and expels it out into the room again. During this whole process, three main important components play the major role. These 3 components are… *Compressor *Condenser Coil *Evaporator Coil Compressor – This component ensures there is proper refrigerant circulation between evaporator coils and condenser. This process is performed in a closed loop. Condenser Coils – They are a collection of several tubes that are filled with refrigerant (mostly Freon). These coils are responsible for eliminating any heat generated from gas refrigerant. And it expels the heat through outside door. It will also cool down the hot refrigerant into liquid again. Evaporator Coils – The work of evaporator coils is exact opposite of condenser coils. These coils have the refrigerant which is responsible for removing heat and moisture present in the room. This process will convert the refrigerant into gaseous form. Now that you have understood the roles of the components individually, now we will dive into the working process of the air conditioner. *When you turn on the inverter AC, first compressor will convert the gas into high-pressure hot liquid. *Next, the hot liquid will flow along the condenser coils for the condensation process. During this process, heat will gradually escape through outdoor unit and liquid will cool down. Though, it cools down, the temperature of the liquid still stays high. *Now, high pressure liquid will be reduced to low temperature liquid through expansion valve. *Finally, low pressure liquid passes through evaporator coils. During this process, heat from the room with absorbed which transforms the liquid into gas As heat is absorbed, you will experience cool air inside the room.
