Phase-change thermal storage floor radiation heating device used at the end of air source heat pump

Abstract

The invention discloses a novel phase-change heat-storage radiant floor heating device for the tail end of an air source heat pump. The phase-change heat-storage radiant floor heating device for the tail end of the air source heat pump comprises a heat supply pipeline and a heating ground surface. The heat supply pipeline comprises a heat supply main pipe and a heat regenerative main pipe, and multiple heat supply branch pipes are connected between the heat supply main pipe and the heat regenerative main pipe through a distributor; the heating ground surface comprises a damp-proof layer, a heat insulating base layer, an aluminum foil layer and a composite floor layer which are arranged on a floor slab layer from bottom to top in a laid manner; the heat insulating base layer is formed by heat insulating materials and precasted phase-change heat-storage material modules which are mutually connected; the heat supply branch pipes are laid in porous channels of the phase-change heat-storage material modules, and the precasted phase-change heat-storage material modules and the heat supply branch pipes in the porous channels are all located in an aluminum shell in a surrounded manner; and the penetrating portions of the aluminum shell and the heat supply branch pipes and the two ends of the aluminum shell are each provided with a sealing ring. According to the phase-change heat-storage radiant floor heating device for the tail end of the air source heat pump, construction and maintenance are convenient, heat supply is even, and in the defrosting process, it is guaranteed that indoor heat enables a user to feel comfortable, the heat supply efficiency is high, and the energy-saving effect is good.

Description

technical field [0001] The invention relates to a heating device laid on a floor or a wall, in particular to a dry floor radiation heating device used at the end of an air source heat pump. Background technique [0002] In my country, the research on floor radiant heating began in the 1950s. With the development and utilization of various pipes and heat sources, my country's low-temperature hot water floor radiant heating technology has also made great progress. Compared with traditional radiators, the energy saving rate of radiant floor heating is more than 30%, and it can better meet the thermal comfort requirements of human body. [0003] Initially, the floor radiant heating was wet-type, but often affected by the level of construction, the ratio and thickness of the concrete in the filling layer were not up to standard, resulting in unsatisfactory heating effects and even cracking of the concrete filling layer. In order to overcome the disadvantages of the wet method, t...

Problems solved by technology

If the existing radiant floor heating method is used, firstly, uneven temperature distribution on the floor surface is likely to occur, and secondly, when the defrosting condition is running, it is easy to cause discomfort to the indoor personnel
