HEAT SUPPLY SYSTEM AND METHOD OF ITS OPERATION ORGANIZATION Russian patent published in 2020 - IPC F24D3/00 F24D17/00 

FIELD: power engineering.

SUBSTANCE: group of inventions relates to power engineering, in particular to heat supply systems for residential and public buildings and industrial premises. Heat supply system includes heating devices, supply and return pipelines, electric drive, two single-section membrane pumps consisting of pump and working chambers connected by rigid rod and being left and right sections of membrane pump. Each section of membrane pump is connected only with its heating device. Heating devices inputs are connected to pump chambers, respectively, of right or left section of diaphragm pump via discharge check valves. Outlets of heating devices are connected simultaneously to return pipeline and, respectively, to pump chambers to right or left sections of membrane pump via suction check valves of right or left section. Additionally it contains two heat exchangers of hot water supply, two regulators of hot water flow rate and two pulse flow distributors with impact valves in inlet and outlet holes and side branches connected with common electric drive and connected in parallel to supply pipeline. Membrane pump working chambers are connected with lateral outlets of pulse flow distributors. Outputs of heating devices and heat exchangers of hot water supply (HWS) are connected in parallel to outlets of pulse flow distributors through hot water flow rate controllers, note here that heat exchangers and HWS heat exchangers are communicated with return pipeline via safety check valves. Method of heat supply system operation organization includes hot heat carrier intake from heat network through supply pipeline, periodically distributing hot heat carrier to two independent circuits by pulse flow distributor due to electric drive, creating periodic pulsations of hot and cooled heat carrier by two sections of membrane pump, connected by rod due to use of pressure drop between hot and cooled heat carriers, as well as generate hydraulic impact, energy of which is used to reduce delay between rod speed and pressure force in its final positions, redistributing pulsating flow of heat carrier between parallel connected heating devices and heat exchangers HWS depending on specified flow rate on hot water flow rate controllers, heat of hot and cooled heat carrier is transferred to ambient air and heated in heat exchangers HWS, cooled heat carrier is returned to heat network via return pipeline, protecting heating devices and heat exchangers HWS from increased pressure in return pipeline through safety check valves.

EFFECT: group of inventions makes it possible to increase heat transfer of heating devices and heat exchangers HWS due to periodic passing of hot and cold heat carrier and to reduce costs for transportation of heat carrier due to use of smaller available pressure of heat network.
