FIELD: machine building.
SUBSTANCE: vapour-compression system consists of compressor, of condenser, of at least two evaporators connected in parallel to facilitate flow of fluid medium between compressors and common outlet orifice and of expander for control of flow rate of cooling agent through each evaporator. The procedure consists in the following stages: there is received a controlled key of distribution determining distribution of used cooling agent between evaporators; there is observed overheat at a common outlet orifice, there is controlled amount of used evaporator depending on overheat to optimise value of overheat; used cooling agent is distributed between evaporators according to the received key of distribution by means of the expander.
EFFECT: raised efficiency of system operation.
