Phase-change heat-storage radiant floor heating device combined with air source heat pump

Abstract

The invention discloses a phase-change heat-storage radiant floor heating device combined with an air source heat pump. The phase-change heat-storage radiant floor heating device combined with 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 heat supply main pipe and the heat regenerative main pipe are each provided with a pressure and temperature sensor and a regulating valve, and the heat regenerative main pipe is provided with a liquid sight device; 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; and the heat supply branch pipes are laid in grooves of the precasted phase-change heat-storage material modules and located on the aluminum foil layer. According to the phase-change heat-storage radiant floor heating device combined with the air source heat pump, construction and maintenance are convenient, heat supply is even, and in the defrosting process, it is guaranteed that the 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 an indoor heating device laid on floors and walls, in particular to a novel heating device for an air source heat pump. Background technique [0002] my country's current energy consumption has leapt to the second place in the world. The primary energy consumption is mainly coal, and the utilization rate of clean energy is low. One of the reasons for the smog that has swept across the country in recent years is that my country's energy structure is not stable. Reasonable. Therefore, we need to optimize the energy consumption pattern and establish a resource-saving and environment-friendly social development constitution. [0003] Although the development time of air source heat pump technology in our country is relatively short, its advantages such as cleanliness, high efficiency and stability promote the rapid development of this technology and have broad development prospects. The Ministry of Construction of my country first...
