The refrigeration unit is widely used in high and low temperature damp heat test chambers. The simplest refrigeration unit consists of four major components: 1 compressor; 2 condenser; 3 throttle valve; 4 evaporator; the following is a brief introduction. Let's look at the role of the evaporator in the high and low temperature damp heat test chamber refrigeration system.
The evaporator is a very important component in the cooling of the high and low temperature damp heat test chamber. Its working condition is that the low temperature condensing "liquid" body passes through the evaporator and exchanges heat with the outside air to "heat" the heat. Reach the cooling effect. The low-temperature and low-pressure refrigerant absorbs heat and evaporates inside, thereby taking away the heat in the high-low temperature damp heat test chamber to achieve the purpose of cooling, that is, heat exchange. The evaporator is also a partition wall heat exchange device. The low temperature and low pressure liquid refrigerant vaporizes and absorbs heat on one side of the heat transfer wall, so that the medium on the other side of the heat transfer wall is cooled. The medium to be cooled is usually water or air. The main function of the evaporator can be summarized in three sentences: 1. absorb heat; 2. this part of the heat vaporizes the refrigerant in the coil to make it vapor; 3. This part of the heat causes the refrigerant vapor in the coil to overheat.
