Abstract

The invention discloses a phase change energy storage device and a paving method thereof. The phase change energy storage device sequentially comprises a heat insulation layer, an electric heating layer, an energy storage material layer, a leveling layer and a surface decoration layer from bottom to top. According to the paving method, the mass and the paving thickness of required energy storage material are accurately obtained according to the heating design thermal load, the total duration of an electricity price peak section and the thermal physical parameters of the energy storage material. The heat storage density of the energy storage material in the floor is large, the phase change temperature is constant, heat energy of the electric heating layer can be stored through the phase change energy storage material, peak-valley electric power transfer is achieved, and electric power waste is reduced; and the mass and the thickness of the energy storage material needed in floor laying can be accurately obtained according to the size of a heating room, heating design parameters and thermal physical parameters of the energy storage material, the defect that the energy storage material cannot be accurately quantified in the existing floor laying process is overcome, heat stored by the energy storage material is fully utilized, energy conservation and environmental protection are achieved, all-day heating is achieved, and the room temperature always meets the human body comfort requirement.

Description

technical field [0001] The invention relates to a building device and a paving method thereof, in particular to a phase-change energy storage device for indoor building materials, a matching method for phase-change energy storage materials in the device, and a paving method for the device, belonging to the technical field of building heating . Background technique [0002] With the development of industrial technology, my country's environmental pollution is becoming increasingly serious. During the heating season in northern regions, coal is mostly used for heating, resulting in an increase in sulfur dioxide and dust particles in the air, which brings greater environmental pressure. Therefore, it is urgent to seek alternative energy sources for clean heating. Electric heating floor radiant heating equipment is flexible in layout and has no pollutant discharge. It is one of the most ideal heating methods. According to the actual law of electricity consumption, the demand f...
