Refrigeration principle |
Steam compress type refrigeration： Its principle is to use freon in the latent heat of evaporation of a liquid from cooling objects, such as heat and refrigeration. The expansion valve into the evaporator liquid, absorbing latent heat of evaporation and evaporation from the surrounding objects, evaporate into low temperature and low pressure gas refrigeration compressor suction, compressed by compressor into a high temperature and high pressure gas into the water cooled or air cooled condenser, which cools into a high-pressure liquid, then through the expansion valve into the evaporator. Repeat cycle, heat from the low temperature refrigeration and heat released from the high temperature. |
