Building heating and cooling system for low energy houses uses domestic water as energy carrier, with hot water piping acting as hot water supply line, and cold water piping as cold water supply line, and with circulating piping as return

摘要

The building heating and cooling system is for low and minimal energy houses and uses domestic water as the energy carrier. The hot water piping is simultaneously the hot water flow supply line, and the cold water piping is simultaneously the cold water supply. The circulation line of the hot and cold water is simultaneously the return. An independent claim is included for a fan heating and cooling component with fresh air suction has two motorized shut-off valves (5) to ensure the alternate operation as a cooling or heating component.
