Wall automatic heat storage and heat removal device and method for achieving wall automatic heat insulation through same

Abstract

The invention discloses a wall automatic heat storage and heat removal device. The device comprises embedded tubes filled with phase change materials used for absorbing heat of a wall, liquid branch tubes, steam branch tubes and a radiation cooling device, wherein working media flow in embedded inner tubes, and accumulated heat can be taken away by the flowing working media; the liquid branch tubes are communicated with one end of each embedded inner tube and used for the liquid working media to flow and enter the embedded inner tubes; the steam branch tubes are communicated with the other ends of the embedded inner tubes, the phase change materials stores and transmits the heat to the liquid working media in the embedded inner tubes, and the liquid working media obtained after heat absorption are heated and then evaporated to be in a gaseous state; the radiation cooling device is communicated with a liquid main tube and a steam main tube separately, and the gaseous working media discharged from the steam main tube enter the radiation cooling device and then are cooled to be in a liquid state and flow into the liquid branch tubes communicated with the radiation cooling device. While the phase change materials are applied, low-grade energy generated by sky background radiation is fully utilized; a wall active heat insulation technology and device are adopted, so that the aims of maintaining the indoor heat comfort and reducing the energy consumption of an air conditioner are achieved.

Description

technical field [0001] The invention belongs to the field of building energy saving and renewable energy utilization, and in particular relates to a wall automatic heat storage and heat discharge device and a method for realizing automatic wall heat insulation by using the device. Background technique [0002] In the whole life cycle of a building, the energy consumption of heating and air conditioning accounts for about 55%-65% of the total operating energy consumption of the building. The rising energy consumption of buildings and the lack of energy make people pay more and more attention to the development of new means and new technologies to save energy. In building energy consumption, the cooling and heating load formed by the heat transfer of the envelope structure is an important part of the total energy consumption. The air-conditioning load caused by the outer enclosure structure accounts for about 30% of the total load. Therefore, reducing the heat transfer of th...
