Abstract

The invention discloses a thermal/power combined drive steam jet type refrigeration device. A condensation pipeline outlet of a condenser is connected with a refrigerant inlet of a booster pump and a refrigerant inlet of an expansion valve. A refrigerant outlet of the booster pump is connected with a refrigerant inlet of a generator. A refrigerant outlet of the generator is connected with a refrigerant inlet of a first depressurization nozzle. A refrigerant outlet of the expansion valve is connected with an evaporation pipeline of an evaporator and is then connected with a refrigerant inlet of a compressor. A refrigerant outlet of the compressor is connected with a refrigerant inlet of a second depressurization nozzle. A refrigerant outlet of the first depressurization nozzle is connected with a refrigerant outlet of the second depressurization nozzle and is then connected with a refrigerant inlet of a diffuser pipe. A refrigerant outlet of the diffuser pipe is connected with a condensation pipeline inlet of the condenser. The invention further provides a thermal/power combined drive steam jet type refrigeration method using the thermal/power combined drive steam jet type refrigeration device at the same time.

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...
