FIELD: refrigeration equipment, particularly using carbon-dioxide.
SUBSTANCE: compression refrigeration machine preferably using carbon-dioxide as refrigerant comprises compressor, heat exchanger, cooler (condenser), expander, liquid coolant separator linked to inlet compressor pipe by pipeline. Pipeline is provided with automatic butterfly valve maintaining constant pressure upstream butterfly valve. Machine also includes pump, connected to electric motor and linked to expander by its shaft, and evaporator. Separator has opened vapor cavity and is installed in air-tight case together with expander and liquid coolant pump. Liquid coolant pump is connected to electric motor and to expander shaft by microprocessor-operated electromagnetic clutches. Microprocessor is linked to compressor.
EFFECT: increased efficiency.
