What component of the air conditioning system converts low-pressure gas into high-pressure gas?

The compressor is the key component of the air conditioning system responsible for converting low-pressure gas into high-pressure gas. In this process, the compressor draws in refrigerant gas that has absorbed heat from the indoor air. As the gas enters the compressor, it is subjected to mechanical energy, which increases its pressure and temperature. This transformation of the refrigerant enables it to move through the rest of the air conditioning system, specifically to the condenser, where it can release the absorbed heat and become a liquid again.

The other components play different roles within the air conditioning system. The condenser is where the high-pressure gas is cooled and condenses into a liquid. The evaporator absorbs heat from the indoor air and allows the refrigerant to evaporate, creating low-pressure gas. The metering device controls the flow of refrigerant into the evaporator but does not affect the pressure of the gas directly. Understanding the function of each component is essential for troubleshooting and maintaining an effective refrigerant cycle in air conditioning systems.
