Question

What is the role of a compressor in an air conditioner

Answer 1

it's the component in the system that raises the temperature and pressure of the vapor refrigerant that leaves the evaporator coil

Answer 2

The compressor is one of the main parts of the cooling cycle. The motor-driven compressor sole function is to "squeeze" the refrigerant, raising its temperature and pressure so that it exits the compressor as a hot, high-pressure gas.
