High energy-saving type energy storage building

Abstract

The invention discloses a high energy-saving type energy storage building. The high energy-saving type energy storage building comprises a solar roof, a phase change wall, a ventilation system, a water supply system and a heat exchange system; the solar roof is arranged on the top of the energy storage building; air circulation pipes is arranged in the solar roof; air circulation pipes and liquidcirculation passages are arranged in the phase change wall, and the air circulation pipes communicate with the air circulation pipes in the solar roof; the ventilation system is connected to a building internal air supply system and the solar roof airflow circulation pipe; the water supply system is connected to a building internal water use system; the heat exchange system communicates with a water supply pipe in the water supply system, the air circulation pipes in the phase change wall, and the air circulation pipes in the solar roof. The solution uses the phase change wall to increase therate of change of indoor air temperature, that is, the indoor temperature rises more slowly during the summer, and the indoor temperature drops more slowly during nighttime in the winter, and the maximum temperature and the lowest temperature are lowered. The indoor comfort is improved, and an energy-saving effect can be achieved.

Description

Technical field [0001] The invention relates to new energy technology, in particular to energy-saving wall building technology. Background technique [0002] Only about 12% of new buildings in China each year meet the national energy-saving standards, and more than 75% of buildings are high-energy-consuming buildings. High building energy consumption and low energy efficiency are the shortcomings of China's construction industry. The development and utilization of new energy sources can effectively make up for this deficiency. As a clean energy, solar energy is inexhaustible and inexhaustible. However, the intermittent nature of solar energy is a more prominent problem. Day and night alternation and weather conditions will affect the utilization and development of solar energy. Therefore, a medium is needed to store solar energy and make it a sustainable energy source. [0003] Phase change material (PCM) is a medium that can effectively store solar energy. Solar energy buildi...

AI Technical Summary

Problems solved by technology

[0004] At present, there have been many researches on the application of phase change wall buildings. However, due to the inherent thermal insulation characteristics of phase change materials, their thermal conductivity is low, and the actual application is affected by the unsatisfactory outdoor environment. There is a defect in energy release

In the energy storage stage, the phase change wall cannot absorb higher radiant heat during the solar radiation time, and the optimal radiation time in a day is lower, such as cloudy and rainy summers, the heat storage efficiency is lower

Moreover, the layout orientation of the building also prevents the wall from storing heat for a long time, so it is difficult to achieve the expected effect only by relying on the phase-change wall to directly heat and store energy.

There will also be incomplete heat release during the heat release stage, and it is difficult to maintain the indoor temperature at night in winter
