As a new star in the special vehicle industry, refrigerator car coolers have broad prospects for development and they will grow along with the cold chain transportation industry. Refrigerated trucks cooler group is an important part of refrigerated trucks, we first look at the principles of refrigeration units, the current refrigerated trucks freezer group with more mechanical refrigeration, consistent with the principles of refrigeration air conditioners, refrigerators, etc., on a point Absorb heat and then give off heat at another point. The refrigerant absorbs heat through a coil (evaporator) in the cargo space and then dissipates heat through another coil (condenser) on the outside. The refrigerant is circulated in the system through a compressor.
The composition of the refrigeration system: refrigerant and four major parts, namely compressor, condenser, expansion valve, evaporator.
1. Compressor and compressor are the power of the refrigeration cycle. It is driven by the motor and keeps rotating. In addition to extracting the vapor in the evaporator in time to maintain the low temperature and low pressure, it also increases the pressure and temperature of the refrigerant vapor through compression, creating The conditions for the transfer of heat from the refrigerant vapor to the ambient media.
2, condenser, condenser is a heat exchange device, the use of ambient cooling medium (air or water), take away the heat from the cold compressor high temperature and high pressure refrigeration steam, cooling, condensing high temperature and high pressure refrigerant.
3, throttling components (ie, expansion valve), high-pressure liquid refrigerant at room temperature directly into the low-temperature scale evaporator, according to the saturation pressure and saturation temperature - corresponding principle, reduce the pressure of the refrigerant liquid, thereby reducing the refrigerant liquid temperature.
4, evaporator, evaporator is also a heat exchange device. After the throttling, the low-temperature and low-pressure refrigerant liquid evaporates (boils) into steam, absorbs the heat of the cooled material, lowers the temperature of the material, and achieves the purpose of freezing and refrigerating the food. In the air conditioner, the surrounding air is cooled to achieve the effect of cooling and dehumidifying the air.
Understanding the working principle and cooling method of refrigerator car cooler, for the enterprise, individual operators have a great role in their purchase of refrigerated trucks have a good guiding role.
