To provide a refrigerating device capable of adjusting the operating condition of a compression refrigerator in accordance with the condition of a cooling load and absorption refrigerating effect, and being economically and efficiently operated.
In this refrigerating device manufactured by combining an absorption refrigerating machine having an evaporator E exercising the refrigerating effect by using exhaust heat as a heat source, a compressor Mc, a first condenser Cc1 cooling with the outside air or the cooling water, and a compression refrigerating machine having a first condenser Cc2 connected to the evaporator E of the absorption refrigerating machine with heat exchange relationship and an evaporator Ec exercising the refrigerating effect, and the compressor Mc is provided with a control means operated when the load to the evaporator Ec can not be coped only by the refrigerating effect of the absorption refrigerating machine. A plurality of compression refrigerating machines can be connected to one absorption refrigerating machine, and the control means operates the compressor Mc on the basis of the difference between a target temperature of a cooled medium and an actual temperature, the evaporation pressure of a refrigerant in the evaporator Ec, and the like.
