SYSTEM OF HEAT SUPPLY AND COLD SUPPLY Russian patent published in 2011 - IPC F24D15/04 F24D3/18 

FIELD: power engineering.

SUBSTANCE: system of heat supply and cold supply consists of a heating plant with a circulation pump and a heat exchanger, supply and return pipelines, heating devices, stop and control valves. A pipeline that supplies a heated coolant to heating devices comprises an inbuilt absorption-refrigerating machine, connected by means of a generator (a boiler) into a pipeline that supplies heat from the heating plant. At the outlet of the absorption-refrigerating machine there is a thermostat, and one or more heating circuits are connected, which comprises supply and return pipelines, and heating devices. The thermostat is installed between a heating plant and heating devices. The thermostat depending on temperature in a heated room may automatically switch direction of coolant movement either via heating devices, and/or into a return pipeline. The system of absorption refrigerating machine cooling comprises a thermostat, which, depending on temperature in the heated room may switch direction of coolant movement into heating devices or into a cooling device.

EFFECT: increased efficiency and convenience of heat supply system operation and cold generation.
