A green phase change box

Abstract

The invention belongs to the field of building energy saving, and in particular relates to a greening phase change box, which includes a flower plate, a tray and an energy storage plate assembled up and down. Phase change materials are laid in the flower plate, the tray and the energy storage plate. The invention lays phase-change materials in the flower pots, trays and energy storage plates, and when the external temperature changes, the heat insulation effect on the roof is achieved through the phase-change materials absorbing or releasing heat; the phase-change materials in the flower pots can Lay special planting soil on it, and plant perennial herbaceous flowers and plants of Crassulaceae or Araceae such as Wannian grass to green the roof environment. The phase change material in the flower pot can also play a role of water storage and promote the growth of fabric rhizomes; The variable boxes are spliced ​​and combined according to the roof design to form a lightweight planting roof heat insulation system.

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.
