Refrigeration system with heat recovery and method for the operation of the refrigeration system

摘要

Refrigeration system (1) with a closed refrigerant circuit, comprising in the direction of flow of the refrigerant at least one compressor unit (5, 6), a heat exchanger (7) of a system for heat recovery, a capacitor (8, 16), a collector (9), an expansion device (11, 13, 15) and an evaporator (2, 3, 4), characterized in that, between the heat exchanger (7) of the system of the heat recovery and the capacitor (8, 16) a control valve (24) are arranged, and that the control valve (24) with a control device (25) is joined, the degree of opening of the control valve (24) as a function of the output of the heat exchanger (7) of the system of the heat recovery, from the condensation pressure of the refrigerant and of the outlet temperature of the heat transfer medium of the heat exchanger (7) of the system of the heat recovery between 0% and 100% can be adjusted.
