HOT WATER SUPPLY SYSTEM WITH THE ORGANIZATION IN IT OF A PULSATING MODE OF MOVEMENT OF THE COOLANT AND HEATED WATER Russian patent published in 2021 - IPC F24D3/08 F24D17/00 

FIELD: heat power engineering.

SUBSTANCE: invention relates to the field of heat power engineering and can be used for heat supply of residential and public buildings and industrial premises. The hot water supply system with the organization of a pulsating mode of movement of the coolant and heated water in it includes the supply and return pipelines, two single-section membrane pumps, consisting of left and right pumping and left and right working chambers, rigidly connected by a rod and being the left and right sections of a double-circuit membrane pump. Discharge and suction check valves are connected to the pumping chambers. Additionally, the system contains left and right main heat exchangers, which are connected on one side, respectively, with return and supply pipelines through valves of bellows temperature regulators, upper and lower inlet valves, working chambers, lower and upper outlet valves, inlet valves. In this case, the upper and lower intake valves, the lower and upper exhaust valves are connected with a switching mechanism rigidly connected to the stem. On the other hand, the main heat exchangers are connected to consumers and water pipelines through bellows temperature regulators, suction check valves, pump chambers, left and right sections of a double-circuit diaphragm pump and delivery check valves. Recirculation pipelines are connected in parallel to the water pipelines.

EFFECT: invention makes it possible to use the potential of the heat carrier to the fullest due to the automatic adjustment of the temperature of the "return" network water, the transformation of the pressure from the heating circuit to the heated one, as well as improving the heat transfer of heat exchangers with pulsating circulation of the heat carrier.
