FIELD: transport.
SUBSTANCE: invention relates to marine air conditioning system water-cooled refrigerators. At different thermal loads at the system, compressor is cut in/out, the number of compressors is varied or compressor rpm is controlled. Depending on coolant preset temperature, definite coolant boiling pressure is set by adjustment of compressor drive rpm variation.
EFFECT: stable preset coolant temperature, machine operation at electric power supply from isolated source.
