The refrigeration principle is divided into two parts: The binary solution is heated and boiled by a heat source in the generator, and the generated refrigerant vapor condenses into a refrigerant liquid in the condenser. The liquid refrigerant enters the evaporator after being throttled by a U-shaped tube, and is sprayed out at low pressure by the evaporator. The liquid refrigerant evaporates, absorbing the heat of the refrigerant, producing a cooling effect. The concentrated liquid flowing from the generator flows into the absorber after being cooled and depressurized by the heat exchanger, and is mixed with the original liquid of the absorber to form a concentrated liquid of medium concentration. The medium concentrated solution is transported and sprayed by an absorption pump, and the refrigerant vapor from the evaporator is absorbed to become a dilute solution. The dilute solution is transported to the generator by the generator pump, and the refrigerant vapor generated by the heat source forms a concentrated solution again, entering the next cycle. In summary, any refrigeration device is composed of four parts (compressor, condenser, evaporator, and throttling device). The refrigerant absorbs or releases heat through changes in the physical state of the refrigerator to achieve refrigeration or heating effects. |
