Three-circuit Heating-cooling Boiler of Innovative Construction

Boiler that is used only for heating the heat carrier is called single-circuit boiler. The heat carrier, which is heated in the boiler furnace with fuel combustion products, circulates in the heat exchangers of the heating system (radiators, heaters, etc.). Boiler, which, in addition to the heating function, has the function of heating domestic water, is called double-circuit boiler (according to the presence of heating and hot water supply schemes). In such devices, part of the heat carrier circulates in the heating system, and part heats the internal water to the required temperature. The article presents a three-circuit heating-cooling boiler of an innovative design, which can be used both for heating the building and for obtaining sanitary hot water, as well as for cooling the building in the air-conditioning mode during the warm period of the year, for which the device is equipped with a refrigeration unit. The construction is universal, compact and in one small volume there is a device that can perform all the above functions.
