Refrigeration compressor working principlePosition:Home > Blog
Single-stage vapor compression refrigeration system, is by the refrigeration compressor, condenser, evaporator and throttle four basic parts. Between them in turn connect pipe to form a closed system, the refrigerant in the system constantly circulating, status changes, the heat exchange with the outside world. The work process is shown in figure 1. Refrigeration system, the basic principle of liquid refrigerant in the evaporator absorbed by the object of cooling heat, vaporized into the low temperature low pressure steam, in the compressor, compressed into high-temperature high-pressure steam back into the condenser, the condenser to the cooling medium (water or air), heat release, condensation of high pressure liquid, the throttle valve throttle for low pressure low temperature refrigerant, again into the evaporator heat vaporization, and achieve the goal of cycle refrigeration. In this way, the refrigerant in the system after evaporation, compression, condensation, throttle four basic process to complete a refrigeration cycle. In the refrigeration system, evaporator, condenser, compressor and throttle valve is the indispensable four items in the refrigeration system, the evaporator is conveying equipment of cold energy. In which refrigerant absorbing heat cooling objects to realize refrigeration. Compressor is the heart, plays a suction, compression, the role of the refrigerant vapor. Condenser is exothermic equipment, will be absorbed in the evaporator heat along with the heat transformation by the compressor work is passed to the cooling medium away. Throttle valve throttling depressurization effect to the refrigerant, at the same time control and adjust the number of flows into the evaporator refrigerant liquid, and the system is divided into the high side and low voltage side of two parts. Actual refrigeration system, in addition to the above four items, often has some auxiliary equipment, such as solenoid valve, distributor, dryer, collector, fusible plug, pressure controller and other parts, they are in order to improve the operation of the economy, reliability and security.
