Greening phase-change box

Abstract

The invention belongs to the field of building energy conservation and particularly relates to a greening phase-change box. The greening phase-change box comprises a flowerpot, a tray and an energy storage plate, wherein the flowerpot, the tray and the energy storage plate are connectedly and vertically assembled and internally provided with a phase-change material by laying. By laying of the phase-change material in the flowerpot, the tray and the energy storage plate, when the external temperature changes, a roof heat insulation effect is achieved through the phase-change material which absorbs or releases heat. Special planting soil can be laid on the phase-change material of the flowerpot, crassulaceae such as sedum makinoi or araceae perennial herbaceous plants can be planted for greening a roof environment, the phase-change material in the flowerpot plays a role in water storage, and plant root growth is promoted. A lightweight planting roof heat insulation and preservation system can be formed by assembly of multiple greening phase-change boxes according to the roof design.

Description

technical field [0001] The invention belongs to the field of building energy conservation, in particular to a greening phase change box. Background technique [0002] Due to the rapid development of urban industry and transportation, the discharge of all kinds of dust and waste gas, the further aggravation of environmental pollution, the relative increase of building density, and the relative scarcity of green spaces have affected the physical and mental health of the people. Real estate development has intensified the reduction of urban green space, increased the heat island effect and air pollution, increasing the greening rate and beautifying the environment are people's expectations. Roof greening plays an important role in haze control, oxygen release, dust removal and noise reduction, especially in the country In the case of strongly recommending green buildings in sponge cities, most cities across the country have stipulated that the roof greening rate should not be l...

Problems solved by technology

[0003] At present, in China, people have made more efforts to solve the problem of roof greening. Some people use concrete and extruded boards to make "sandwich" templates, some people use steel frames to make flower stands, and some people use plastics. Planting trays, etc. Although these methods have solved the problem of roof greening to varying degrees, but at the same time, there are problems that the system cannot meet the thermal performance requirements of the roof, or the process is complicated, or the cost is high, or the versatility is not high, and the flexibility is not high. strong, or it is not convenient for later maintenance, or the fire resistance performance does not meet the requirements, etc.
