Document Type and Number:
Japanese Patent JP2019027646
Kind Code:
A
Abstract:
To provide a supply air preheating device capable of reducing load and cost for construction by suppressing a piping length for circulating hot water to a heat exchanger for heating outside air and supplying it into a room even in a case where the heat exchanger is provided in an air supply port in a habitable room away from a heat source machine, and capable of enhancing heat efficiency in floor heating, and a heating system.SOLUTION: In a heating system, a heat releasing unit 10 attached to an air supply port connecting outdoor side and indoor side through a wall is inserted into return piping at a downstream side of a hot water mat for floor heating. Hot water branched from outgoing piping 21 to the hot water mat 20 by a first branch part 24 and hot water branched from return piping from the hot water mat 20 by a second branch part 26 are mixed by a mixer 27 and returned through the heat releasing unit 10 to return piping 22 by a confluent part 30 at a downstream side of the second branch part 26.SELECTED DRAWING: Figure 5
