Solar phase change heat storage wall and ventilation system provided with same

Abstract

The invention provides a solar phase change heat storage wall and a ventilation system provided with the same. The solar phase change heat storage wall is formed by connecting a high-temperature phase change layer, a medium-temperature phase change layer and a low-temperature phase change layer sequentially, wherein the phase change temperatures of the high-temperature phase change layer, the medium-temperature phase change layer and the low-temperature phase change layer are set from high to low. A glass cover plate is arranged on the south side of the outer wall of the ventilation system; the rest part of the ventilation system is composed of an enclosure structure; an outdoor air inlet is formed in the upper part of the north side of the outer wall; and an outdoor air outlet is formed in the upper part of the south side. The solar phase change heat storage wall is positioned in the outer wall and close to the glass cover plate; the high-temperature phase change layer faces south; and an upper vent hole and a lower vent hole are formed in the upper part and lower part of the solar phase change heat storage wall respectively. A hot water system penetrates through the solar phase change heat storage wall to perform heat exchange. The solar phase change heat storage wall can overcome shortcomings of a conventional heat collection wall, has the advantages of good heat storage capability, diversified functions, simplicity for operation and no energy consumption, can achieve the effects of cooling by ventilation and domestic water heating in summer, and can be used for providing heat in winter, thereby having good application prospects.

Description

technical field [0001] The invention relates to a solar energy utilization system, in particular to a solar phase change heat storage wall and a ventilation system with a solar phase change heat storage wall. Background technique [0002] According to the data of the "2013-2017 China Intelligent Building Industry Market Prospect and Investment Strategic Planning Analysis Report" by Qianzhan Industry Research Institute, the proportion of my country's building energy consumption in total energy consumption has risen to 27.45%. The energy consumption of HVAC and hot water systems accounts for more than 60% of the total energy consumption of buildings. Building energy conservation and emission reduction has become an urgent problem to be solved. my country has a large population and various living forms. Although urbanization is developing rapidly, there are still a large number of independent houses with relatively simple structures and high energy consumption levels in the vas...

Problems solved by technology

However, the heat collecting wall is an ordinary wall with limited heat storage capacity and single function

And it is difficult to apply in winter working conditions, it cannot achieve self-circulation heating of indoor airflow, the heating effect is poor, and even the indoor temperature can be lowered
