The invention relates to a YXY-type vacuum supercharging jetting and
vacuum evaporation refrigerating ditype device, which consists of an evaporating tank, a
storage tank, a compression unit, a vacuum
vaporization refrigerating
pipe, a supercharging liquefying heat discharging
pipe, a vacuum meter, a pressure meter, a jetting device, a retaining valve and a liquid discharging valve, which are serially connected with one another, and the YXY-type vacuum supercharging jetting and
vacuum evaporation refrigerating ditype device is characterized in that: the
evaporation tank is higher than the
storage tank. The YXY-type vacuum supercharging jetting and
vacuum evaporation refrigerating ditype device has beneficial effects that: a novel technical way can be created, and a novel way for widely utilizing
Carnot Cycle theory is provided, so the
Carnot Cycle theory can be perfectly played and adequately utilized. The high vacuum self-sucking vapor and liquid mixed jetting pump compression unit is utilized to realize the vacuum and supercharging jetting
refrigeration and the
evaporation refrigeration technical means. Only 1.6 to 2MPa of the
refrigerant is required, the flow rate of the vapor reaches 4L / s, and the flow rate of the liquid is only 200g / s, so the refrigerating capacity of present 2000W compression unit can be realized by configuring a motor with the power of 1200W. Three embodiments are provided according to the attached graph.
