Embodiment Construction
[0024] figure 1 Among them, use evaporation tank 1, storage tank 2, rotary vane vacuum / booster jet pump 3, vacuum vaporization refrigeration pipe 4, pressurized liquefaction heat release pipe 5, vacuum gauge 6, pressure gauge 7, ejector 8, and one-way valve 9, 10, drain valve 11 and pipeline 12 are connected in series in an orderly manner to form a YXY type vacuum booster injection and vacuum evaporative refrigeration type II device using a rotary vane vacuum / boost jet pump. Evaporation tank 1 is higher than storage tank 2. An oil mark 13 is arranged on the storage tank 2 . The one-way valve 9 is a normally open valve, and the one-way valve 10 is a normally closed valve.
[0025] figure 1 The working process of the refrigerating cycle in the embodiment can be briefly described as: start the rotary vane vacuum / booster jet pump 3, and generate a pressure difference between the two ends of the check valve 9 and the check valve 10. Under the action of this pressure difference,...
