One path of low-temperature and high-pressure refrigerant liquid after heat release by condensation flows into the expansion valve 4 to be throttled, the throttled low-temperature and low-pressure refrigerant liquid is evaporated in the evaporative condenser b6 to absorb heat, and the high-temperature and low-pressure refrigerant gas after heat absorption is ejected in the two-phase ejector 5; the other path flows into the two-phase ejector 5 as a working fluid. The two-phase refrigerant after the working fluid and the injection fluid are mixed enters an evaporative condenser a7 to be evaporated and absorbed into high-temperature low-pressure refrigerant gas, and then enters a compressor 1 to be compressed, so that the cycle is completed.
In the sea water desalination system, sea water from a main sea water system respectively enters a high-temperature evaporator a2 and a high-temperature evaporator b3, exchanges heat with a refrigerant in a vacuum state and then evaporates to generate steam, respectively enters a steam ejector a10 and a steam ejector b9 as working fluid, drives the two steam ejectors to generate vacuum, and respectively ejects steam in a low-temperature evaporator a12 and a low-temperature evaporator b 11; seawater from the main seawater system enters the low-temperature evaporator a12 and the low-temperature evaporator b13 respectively, and is evaporated at a lower temperature in a vacuum environment to generate steam, and is ejected by the steam ejector a10 and the steam ejector b9 respectively. The seawater evaporates and absorbs heat to enable the temperature range in the two low-temperature evaporators to be 10-20 ℃. The steam ejected from the steam ejector a10 and the steam ejector b9 respectively enter the evaporative condenser a7 and the evaporative condenser b6 to exchange heat with the refrigerant for condensation, and the produced fresh water enters the fresh water tank through the fresh water pump 8.
Seawater from the main seawater system drives the jet pump 13 and is discharged to the outside, so that the jet pump 13 generates vacuum. The jet pump 13 pumps the remaining high salt amount seawater in the high temperature evaporator a2, the high temperature evaporator b3 and the low temperature evaporator a12, the low temperature evaporator b11, and the air in the evaporative condenser a7, the evaporative condenser b6 to maintain the vacuum degree of the whole system.
