A self-regulating phase transition Trombay wall

Abstract

The invention discloses a self-regulating phase change Trombe wall. The self-regulating phase change Trombe wall is composed of a glass layer (1), an air layer (2), a first phase change wall layer (3), a first thermal insulating layer (4), a concrete wall layer (5), a second thermal insulating layer (6) and a second phase change wall layer (7) which are sequentially arranged from outside to inside, wherein the phase change temperature of the first phase change wall layer (3) is 27-29 DEG C; the phase change temperature of the second phase change wall layer (7) is 17-19 DEG C; both the first phase change wall layer (3) and the second phase change wall layer (7) are obtained by melting and blending the raw materials including high-density polyethylene, expanded graphite and paraffin. By improving the key heat storage wall structure, the setting manner of the heat storage wall structure, the setting mode of a ventilation port, the switching conditions of opening and closing states and the like, the self-regulating phase change Trombe wall can effectively solves the problem in the prior art that Trombe walls are insufficient in heat supply in winter days without sun or too hot in summer.

Description

technical field [0001] The invention belongs to the field of civil buildings, and more specifically relates to a self-regulating phase-change Trombay wall, which can be applied to the fields of civil building heating and air conditioning energy saving, solar energy utilization, green building energy saving, passive building energy saving and the like. Background technique [0002] The building sector accounts for about 40% of global energy consumption, of which 60% is used for cooling and heating. Under the double impact of energy and environment, building energy-saving technology has attracted increasing attention, among which the Trombay passive wall system has received widespread attention due to its good energy-saving effect. The traditional Trombay wall is used for heating in winter, but there are problems of insufficient heating in winter and overheating in summer, which limits its energy-saving potential and application promotion. [0003] The Trombay Wall is a passi...

Problems solved by technology

Although this method has found a packaging method, it cannot function in both winter and summer due to the use of a phase change material (only one phase change temperature).

This is the second limitation of existing technology
