HEATING AND HOT WATER SUPPLY SYSTEM FOR DOUBLE-CIRCUIT BOILER Russian patent published in 2024 - IPC F24H1/00 F24D3/08 

FIELD: heat engineering.

SUBSTANCE: device relates to heat engineering and can be used for heating cold water for hot water supply (HWS) at small industrial enterprises and in domestic conditions when connected to a double-circuit boiler. Heating and hot water supply system for a double-circuit boiler is a device that contains at least two tanks of the hot water supply system in contact through the walls with the heating system heat carrier enclosed in the third tank or pipes, nozzles of each of the two hot water tanks are connected to each other by a bypass or a three-way switching valve controlled by a given temperature and are connected to a secondary heat exchanger of a double-circuit boiler, two other pipes of hot water supply tanks are connected to cold water supply system and a three-way thermostatic valve for supplying constant temperature to the water sampling point, all connections are carried out taking into account the direction of water movement when connected to a double-circuit boiler, in addition, these nozzles can be used to connect a circulating pump of a hot water supply system, the activation of which is synchronized with a controlled bypass or a three-way switching valve, wherein to one double-circuit boiler several such devices can be connected in parallel, the whole device has heat insulation along the external circuit of the tanks.

EFFECT: automation of the process of heating water supplied from the cold water supply system with minimum energy and economic costs, with a minimum period from opening of the tap by the consumer until the hot water of the specified temperature appears in the tap.
