What is a condenser and evaporator?

The main difference between an evaporator and a condenser is that the evaporator is used to absorb heat and the condenser is used to reject heat.
The condenser is part of the refrigeration system and is a type of heat exchanger. It converts gas or vapor into liquid and quickly transfers the heat in the pipe to the air near the pipe. The working process of the condenser is exothermic, so the temperature of the condenser is high.
The evaporator is also a very important part of refrigeration. The low-temperature condensed liquid exchanges heat with the outside air through the evaporator, vaporizes and absorbs heat to achieve the cooling effect.
