FIELD: engines and pumps.SUBSTANCE: method of cold generation, as per which a cooling agent is evaporated subsequently in an evaporator, its pressure is increased in a compressor, cooled and condensed in a condenser. After that, its pressure is decreased and it is returned to the evaporator. Cooling agent pressure is decreased during a periodic process. It involves the following: accumulation of a cooling agent leaving the condenser in a tank before its filling, pumping-out with a compressor of cooling agent vapours from the tank till the pressure is achieved in it, which is equal to pressure in the evaporator, and supply of the rest cooling agent in the tank to the evaporator.EFFECT: increasing refrigerating factor of refrigerating machines and a conversion factor of heat pumps.3 dwg |
