REFRIGERATOR-ECONOMISER Russian patent published in 2009 - IPC F25B29/00 F25B27/00 F25D11/00 F25D23/12 F24D17/00 F24D17/02 

FIELD: personal demand items.

SUBSTANCE: refrigerator-economiser (RE) is a double-purpose thermal converter in which a domestic refrigerator with a cooling unit and a control unit is the base unit. The first and the second circulation circuits of intermediate heat carrier (IHC) consist of internal segments located inside RE, and external segments located outside RE can be attached to them by means of inlet/outlet connection pipes. In RE housing there made are internal segments of the above two circulation circuits of intermediate heat carrier, which include an additional evaporator and an additional condenser, hydraulic automation elements of the first and the second circuits with piping, switching devices of the first and the second circulation circuits of IHC in order to directly supply the heat from external source to external receiver without using the cooling unit, and connecting pipelines. At the inlets of the first and the second internal segments of circulation circuits of IHC there located are IHC temperature sensors connected with communication channels to the control unit. Communication channels of the control unit with inlet/outlet connectors provided in RE housing are made with the possibility of being attached to the above connectors of RE communication channels with actuating and measuring automation devices in external segments of IHC circulation circuits.

EFFECT: enlarging the number of equipment utilising and using waste energy, environmental energy resources, saving the fuel resources consumed for hot water supply, heat supply, and as a result, reducing CO₂ emissions.
