Problems solved by technology
[0003] The efficiency of this cycle process is not high, the main reason is that there is violent non-uniform mixing in the mixing chamber, that is, the gas-liquid mixture flowing out of the Laval nozzle has a high flow rate, while the flow rate of the refrigerant vapor flowing out of the evaporator Very low, there must be a large completely inelastic collision loss when mixing

Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a heat / work combined drive steam jet refrigeration device and a refrigeration method thereof. Background technique [0002] Heat-driven vapor ejection refrigeration systems can utilize low-grade heat sources to achieve refrigeration through ejection refrigeration cycles. This cycle usually consists of the following equipment: 1. Booster pump and generator. The booster pump pressurizes part of the liquid refrigerant at ambient temperature to the pressure of the generator, and absorbs heat from an external heat source in the generator. Part of the liquid refrigerant is heated to obtain high-temperature and high-pressure refrigerant liquid, gas-liquid mixture or steam; 2. Laval nozzle, whose function is to expand and depressurize the generated high-temperature and high-pressure refrigerant to obtain a high-speed gas-liquid equivalent to the pressure of the evaporator...
