VAPOUR COMPRESSION COOLING UNIT OPERATING METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2010 - IPC F25B1/00 F25D11/00 

FIELD: power industry.

SUBSTANCE: method involves processes of compression and expansion - throttling of working medium-freon, freon heat exchange with environment at its condensation in condenser and freon heat exchange with low temperature heat source at its evaporation in evaporator; and according to the invention, freon compression process both in the area of gases, and in two-phase wet vapour area is performed in compressor by force interaction of unipolar charged freon flow with electric field owing to viscous interaction of charged particles-ions with neutral working medium molecules. Freons are not dissolved either in mineral, or in synthetic oils, and operating mode and its control is performed by changing the voltage of power supply which changes freon flow rate, its pressure and condensation temperature.

EFFECT: high heat transfer coefficient in condenser and evaporator at small heat exchange surface.
