supermarket refrigerated showcase structure and principle
refrigerant circulates repeatedly in the supermarket refrigerated showcase refrigeration system, transferring the heat in the supermarket refrigerated showcase to the surrounding air through the refrigerant, so that the supermarket refrigerated showcase can achieve Refrigeration purpose. The high temperature (70℃~90℃), high pressure (0.9MPa-l.lMPa) gaseous refrigerant in the process of flowing through the condenser (the pipeline is very long), gradually radiate heat and cool down and condense into a liquid refrigerant. The capillary tube is smaller than the throttling and pressure reduction effect of the capillary tube. When the liquid refrigerant reaches the evaporator, it becomes low pressure (0.4MPa~0.6MPa), its boiling point drops and quickly vaporizes and absorbs heat, which makes the temperature in the supermarket refrigerated showcase drop. The low-pressure gaseous refrigerant vaporized by the evaporator is sucked by the compressor again and compressed into high temperature and high pressure, and sent to the condenser by the anti-dew pipe. The refrigeration can be achieved by repeating the above process. When the
refrigerant is running and cooling the compressor, the status, pressure, and temperature of each device (pipeline) are different. After the compressor stops, the pressure of the refrigerant in the refrigeration system is the same, and the average pressure is 0.191MPa~0.22MPa. Although there are many kinds of refrigeration systems in ordinary supermarket refrigerated showcase, the difference is not big. The number and position of anti-exposure pipes are somewhat different, but they must be between the compressor exhaust pipe and the dryer filter pipe. For a few ordinary supermarket refrigerated showcases, a rotary compressor needs to be added to the refrigeration system. Its structure and working principle are the same as the indirect refrigerated showcase refrigeration system.
