FIELD: refrigerating equipment.
SUBSTANCE: invention relates to the refrigeration equipment. Refrigerating plant includes compressor (301), condenser (302), expansion device (304) and evaporator (305) connected with possibility of fluid flow with formation of cooling cycle for refrigerant. Compressor (301) has variable operating power, and said expansion device (304) has variable resistance to said refrigerant passing through said expansion device. Control unit (300) is configured to determine current operating power of said compressor (301) and to control resistance of said expansion device (304) depending on said operating power of said compressor (301). Control unit (300) is configured to control resistance of said expansion device (304) in order to achieve weight flow rate of said refrigerant through said expansion device (304) corresponding to weight flow rate of said refrigerant through said compressor (301).
EFFECT: providing stable cycle of cooling for different working power of compressor.
