There is provided a heat pump installation for the heating of tap water and for room heating purposes e.g., associated office spaces in large warehouses where a number of refrigerators are operating. The heat pump receives its input heat from the heat liberated by the refrigerators. In order to protect the refrigerators from the influence of the heat pump, and in order to accomplish a smooth operation of the heat pump, the installation according to this invention exhibits the features, that the evaporator device of the heat pump is arranged in the form of parallel-coupled evaporator units each of which is assigned an expansion valve controlled by the refrigerant pressure at the unit outlet; THAT A BY-PASS LINE CONTAINING A VALVE WHICH OPENS WHEN THE OUTLET PRESSURE REDUCES, IS ARRANGED BETWEEN THE HIGH-PRESSURE SIDE OF THE HEAT PUMP COMPRESSOR AND THE REFRIGERANT CIRCUIT OF THE HEAT PUMP, FOLLOWING THE EVAPORATOR UNITS; THAT ANOTHER BY-PASS LINE WITH A VALVE CONTROLLED BY THE PRESSURE OR TEMPERATURE AT THE INLET SIDE OF THE COMPRESSOR, IS ARRANGED IN PARALLEL WITH THE EVAPORATOR UNITS OF THE HEAT PUMP; AND THAT EACH EVAPORATOR UNIT OF THE HEAT HEAT PUMP IS ARRANGED IN A HEAT-EXCHANGING RELATIONSHIP WITH ITS PARTICULAR FIRST CONDENSOR UNIT IN EACH CONDENSOR DEVICE OF THE REFRIGERATORS SAID CONDENSOR DEVICES COMPRISING IN EACH CASE AT LEAST ONE ADDITIONAL CONDENSOR UNIT FOR THE DISSIPATION OF THE RECIDUAL HEAT, FOR EXAMPLE TO THE OUTDOOR AIR, A THIRD BY-PASS LINE BEING ARRANGED IN PARALLEL WITH THE SECOND CONDENSOR UNIT, AND A CONTROL MEANS BEING ARRANGED TO CONTROL THE FLOW DISTRIBUTION BETWEEN THE CONDENSOR UNITS AS A FUNCTION OF THE DESIRED REFRIGERANT PRESSURE AFTER THE CONDENSOR DEVICE.

An installation for heating a fluid by utilizing the waste heat from a plurality of refrigerators, said installation comprising a plurality of refrigerators in combination with a heat pump, each of said refrigerators comprising a first refrigerant circuit including, in series, a first evaporator, a first compressor, a first condenser device and a first expansion valve, said heat pump comprising a second refrigerant circuit including, in series, a second evaporator device having expansion means, a second compressor and a second condenser, said heat pump being arranged to receive via said second evaporator device, the thermal energy from said first condenser device of the refrigerator, and to heat said fluid by heat exchange at said second condenser, said second evaporator device being arranged in the form of parallel-coupled evaporator units each of which is connected to an expansion valve controlled by the refrigerant temperature at the unit outlet; a first by-pass line including a valve, openable when said unit outlet pressure is reduced, arranged between the high pressure side of said second compressor and said second refrigerant circuit, following said second evaporator device; a second by-pass line having a valve controlled by the temperature at the inlet side of said second compressor, arranged in parallel with said second evaporator units being arranged in a heat exchanging relationship with its particular first condenser device of the refrigerators, said first condenser devices each comprising at least one additional condenser unit for the dissipation of the residual heat, a third by-pass line being arranged in parallel with said additional condenser unit, said third by-pass line having therein control means arranged to control the flow distribution between the condenser units as a function of the desired refrigerant pressure after the condenser device.
