What is the evaporator on a ac unit?

The evaporator in an air conditioning unit is a critical component that absorbs heat from the indoor air. It contains refrigerant that evaporates at low pressure, causing it to absorb heat as it changes from a liquid to a gas. This process cools the air that is then circulated back into the living space. The evaporator works in conjunction with the condenser, which releases the absorbed heat outside.
