The role and common types of evaporators in the refrigeration cycle

The evaporator is also a heat exchange device in the refrigeration system. Its function is to evaporate the low-pressure liquid refrigerant in the evaporator. The evaporator needs to be cooled (such as water, air, etc.) to transfer heat to the refrigerant. The refrigerant after the endotherm is evaporated from a low-pressure liquid to a low-pressure gas and enters the compressor for the next refrigeration cycle.
The temperature of the medium (water or air) after transferring heat to the refrigerant can be lowered, and the cooled water or air is used to transport it to the air conditioner as a cold source of the air conditioner.
The water that is generally cooled from the evaporator is referred to as "refrigerated water." The evaporative tube in the cold storage is installed in the freezer, which directly absorbs the heat inside the object to reduce the temperature required for freezing (including rapid cooling) and refrigeration. There are many types of evaporators.
Commonly used in air conditioning refrigeration systems are full liquid horizontal shell and tube evaporators and dry shell and tube horizontal evaporators.
