Problems solved by technology

[0004] (1) The heat storage capacity of the traditional heat collection and storage wall is limited, which cannot meet the thermal comfort demand at night; the heat storage and release rate of the phase change heat collection and storage wall is low, and the heating efficiency is low
[0005] (2) Poor thermal insulation performance, resulting in more heat loss in winter and lower utilization rate of stored heat
[0006] (3) The heat insulation performance is poor, resulting in overheating in the room in summer, which does not meet the thermal comfort requirements in summer

Abstract

The invention belongs to a phase change heat collecting-heat dissipation wall system operating under full working conditions in the technical field of building energy saving. The phase change heat collecting-heat dissipation wall system comprises a glass cover plate arranged on a room window, a heat storage wall is arranged inside the glass cover plate, and a decorative plate is arranged inside the heat storage wall. A top opening of the glass cover plate communicates with the outdoor, and a double-cavity channel is formed by opening of the top end and the bottom of the heat storage wall. Thetop end and a bottom opening of the decorative plate communicate with a room, and an outdoor exhaust suction fan and an indoor air supply suction fan are separately installed at the top opening of theglass cover and the top opening of the decorative plate. A thermal insulation roller blind is installed inside the glass cover. The heat storage wall realizes winter heating and summer cooling of a phase change material with different phase transition temperatures, an outside phase change material with a perforated aluminum plate attached to the outer side and an inside phase change material surface longitudinal vortex generator by starting different operating modes in winter and summer. The phase change heat collecting-heat dissipation wall system has broad application prospects and popularization value in areas at which solar energy resources are enriched and the temperature difference between day and night is large.

Description

technical field [0001] The invention belongs to the technical field of building energy conservation, and relates to a phase-change heat collection-radiation heat-dissipation material that adopts phase change materials with different phase change temperatures, and is combined with thermal insulation roller blinds and fans to adjust the indoor thermal environment and can be used under working conditions throughout the year. wall system. Background technique [0002] The northern part of my country is relatively cold and is the main area for heating. The heating energy consumption of northern cities and towns is 184 million tce, accounting for 21% of building energy consumption. volume continued to grow. Therefore, reducing building heating energy consumption is of great significance for building energy conservation. Improving the thermal insulation and heat storage performance of the building envelope and utilizing renewable resources such as solar energy can reduce building ...
