In order to provide engineers with a comprehensive knowledge of high-low temperature alternating test chambers, or to learn, or to refer to, or to know the new, Xiaobian will gradually introduce a series of high-low temperature alternating test chamber application knowledge summary series, please Keep an eye out. Today, the operating principle of the high and low temperature alternating test chamber evaporator is described.
The operating principle of the high and low temperature alternating test chamber evaporator can be roughly divided into three steps:
First, the liquid refrigerant flows into the evaporator and is divided into two ways: up, down, and down.
Second, the heat of the outside air is transferred to the refrigerant in the tube, so that the surrounding air is cooled by the loss of heat, and the refrigerant evaporates because it absorbs heat.
Third, after the heat is absorbed, the steam is generated in the evaporator, and the compressor removes the steam to ensure the low-pressure state of the liquid refrigerant, so that the liquid refrigerant can be evaporated at a lower temperature, and also absorbs heat. The refrigerant provides enough space.
The working principle of the evaporator of the high and low temperature test chamber seems to be simple, but it is an indispensable part, which is an important part to ensure the cooling of the test chamber.
