Energy-storage and temperature-regulating wall system coupled with renewable energy and its application method

Abstract

The invention provides a renewable energy coupled energy storage and temperature regulation wall body system and a using method thereof. The renewable energy coupled energy storage and temperature regulation wall body system is characterized by comprising a temperature regulation wall body, a solar energy device and a shallow soil heat exchange tube; the solar energy device is arranged on a roof of a room; the shallow soil heat exchange tube is buried in the ground; the temperature regulation wall body is connected with the solar energy device and the shallow soil heat exchange tube; one end of the shallow soil heat exchange tube is connected with a water supply pipeline three-way reversing valve, a heat exchange tube water pump and a heat exchange tube flow meter; the other end of the shallow soil heat exchange tube is connected with a water return pipeline three-way reversing valve through a pipeline; the temperature regulation wall body comprises an inner wall plastering layer, a phase change energy storage plate, binding mortar, an inner wall body and an outer wall plastering layer in turn along the direction from interior to exterior; small pipe diameter of coiled pipes are uniformly embedded in the phase change energy storage plate along the direction of the height of the wall body; a water inlet end and a water outlet end of the small pipe diameter of coiled pipes re located at the bottom of the temperature regulation wall body. The using method is divided into three working condition modes of the winter working condition mode, the summer working condition mode and the transition season working condition mode.

Description

technical field [0001] The invention relates to the technical fields of building energy saving and renewable energy utilization, in particular to an energy storage temperature-regulating wall system coupled with renewable energy and a method for using the same. Background technique [0002] Using solar energy to provide thermal heating to reduce building energy consumption and replace the energy consumption caused by conventional fossil energy for heating has broad prospects. However, in the thermal utilization of solar energy, it is easily affected by factors such as rain, day and night, smog, and seasonality, and is unstable. Generally, it can only use the radiation amount of direct sunlight, and the absorbed solar heat is very limited. Large-scale alternative to conventional energy. Generally, the use of solar energy for direct heating must be equipped with an auxiliary heat source system. Due to the discontinuity and inhomogeneity of solar energy distribution, the auxil...

Problems solved by technology

Its shortcoming is that the patent places the phase change material at the hot water tank, which not only makes the amount of the phase change material smaller to a certain extent, but also has a lower energy storage capacity, and most importantly, it ignores the phase change material to maintain room temperature stability This function; secondly, the summer working condition is completely solidified, and the inter-seasonal application of phase change materials to adjust the indoor temperature cannot be realized, and can only be used in the heating season; again, the temperature of the hot water provided indoors is too high, which will cause The emergence of extreme problems such as indoor overheating or rapid drop in room temperature after heating is stopped

[0005] The Chinese patent No. ZL201320137266.1 discloses a household central solar heating system, which is used to provide heat for the floor heating in the house. Its disadvantage is that the system can only be used in the heating season and cannot be used across seasons; Secondly, the phase change material in this system is only used as a heat storage unit, and the role of the phase change material in maintaining room temperature stability is ignored.
