What is the function of a car air conditioning evaporator?

[LukeLynn]

The function of a car air conditioning evaporator is to allow low-temperature condensed gas to pass through the evaporator, exchange heat with the outside air, absorb heat through liquefaction, and achieve a cooling effect. Like the condenser, the evaporator is a heat exchanger, also known as a cooler, and is the direct component in the refrigeration cycle that produces cold air. Here is some additional information: 1. The evaporator is a heat exchanger where high-pressure liquid refrigerant enters through the expansion valve. Due to the atomization effect of the expansion valve, the liquid refrigerant turns into a mist, which then changes into a gaseous state under low-pressure conditions. 2. During this transformation process, heat is absorbed, making the evaporator cold. When air passes through it, it turns into cool air, achieving the purpose of cooling.
