Refrigeration principle		Refrigeration methods are divided into vapor compression refrigeration, absorption refrigeration, vapor injection refrigeration, gas expansion refrigeration, thermoelectric refrigeration. Among the above refrigeration methods, vapor compression refrigeration is the most economical and most widely used refrigeration method, and it is also the most commonly used refrigeration method in environmental test equipment. The principle is to use the latent heat of evaporation of freon and other liquids to absorb heat from the cooled object to achieve refrigeration. The liquid that is throttled into the evaporator through the expansion valve absorbs the latent heat of evaporation from the surrounding objects and evaporates. After evaporation, it becomes a low temperature and low pressure gas that is inhaled by the refrigeration compressor. After being compressed by the compressor, it becomes a high temperature and high pressure gas into the water-cooled condenser, where it is cooled into a high pressure liquid, and then enters the evaporator through the expansion valve. This cycle is repeated, absorbing heat from the low temperature to achieve cooling, and then releasing heat from the high temperature.
