FIELD: refrigeration or cooling.
SUBSTANCE: method comprises connecting the first heat exchanger used for defreezing the compressor, second heat exchanger, and expanding device through pipelines to define united closed circuit so that, for the cycle of defreezing of the first heat exchanger, the gas coolant flows through the first heat exchanger virtually at the same pressure at which the gas coolant outflows from the compressor, so that the gas coolant flowing through the first heat exchanger heats the first heat exchanger thus providing its defreezing.
EFFECT: enhanced efficiency and .
