A combined system of service water heating and a heating medium for domestic heating

摘要

The purpose of the notification is an integrated service water heating system and a central heating medium for the house. The system shall include at least two independent heating media sources, such as a boiler (1) and/or a set of solar panels (12) or a heat pump, etc.,by primary circuits (24, 25) connected parallel to the integrated system (21) via a flat-rate heat exchanger (22),a heat from a heating medium collecting heat from parallel circuits, both for central heating (11) and for district heating (23) with an interface through its own plate heat exchanger (8),the said parallel circuits (23, 11, 24, 25),including return sections, are interconnected by plate heat exchangers (8, 22),to be concentrated in an integrated system block and are interchangeable with each other, in particular depending on the different level of achieved temperatures of at least two over-stratified layers of the heating medium in the external heating medium (20), parallel to the circuit inputs/outputs (23, 11, 24, 25) by means of a differential connection of a group of three-way valves (16, 17, 18, 19),Priority through input/output (27) in the outer reservoir (20) to circuit (11) for central heating and through input/output (26) in the outer reservoir (20) for the heating of the operating water initially for circulation (23) for the heating of the operating water from the upper layer of the heating medium by means of three-way mixing valves (17,7) for a differential switching to a circuit (23) of service water heating not exceeding 55oC or to a circuit (11) of central heating at a temperature even above 55oC.
