[0003] Invention patent CN107883421A "Phase Change Energy Storage Capillary Network Radiation Floor / Ceiling Heating / Cooling Integrated System", discloses "the combination of high-temperature phase change materials at 30°C to 438°C and floor capillary network radiation heating, 16°C to 20°C The technical scheme of combination of low-temperature phase change material and / ceiling capillary network radiation cooling end, which uses two ends of the ceiling and the floor respectively, and the cost is relatively high
However, since the double-effect phase-change plate is a uniform mixture of two types of phase-change materials, the phase-change materials in the second half of the capillary still have the problem of being difficult to melt / solidify
Moreover, the preparation process of the double-effect phase change plate is relatively complicated and the cost is high.
In addition, the capillary network is directly embedded in the double-effect phase change plate, which needs to transfer the cold / heat to the plate first, and then to the room, so it is impossible to quickly adjust the room temperature

Abstract

The invention discloses a cold / heat storage and supply cascade phase change capillary network radiation wall tail end device. The device comprises a base layer wall (1), a heat preservation and insulation layer (2), a damp-proof layer (3), a keel and a phase change capillary network structure jointly composed of a cascade phase change material layer and a capillary network layer. Compared with the prior art, the device provided by the invention can realize the annual use of the phase change material and avoid the waste of the phase change material; and natural cold energy at night can be stored, the mechanical refrigerating capacity of equipment in the daytime is reduced, and energy consumption and operation cost can be reduced. The device adopts an aluminum foil bag for macroscopically packaging the phase change material, and is simpler in packaging and lower in cost compared with a phase change material shaping packaging process; and the device is high in applicability and can be coupled with various cold source / heat source devices. The tail end device is coupled with low-grade renewable energy equipment such as a solar heat collector and a sky radiation cooler, the defect that renewable energy is unstable in supply can be overcome, and all-day cooling in summer and all-day heating in winter are achieved.

Description

Technical field[0001]The present invention belongs to building heating, new technologies and energy storage technologies, and more particularly to the end of a cascade phase change capillary mesh radiation wall.Background technique[0002]The capillary network can be used as a heat source of 35 ° C to 40 ° C as a heat source, 10-15 ° C high-temperature cold water as a cold source, which is advantageous for use in the construction energy system. The phase change material can vary, absorb or release a large amount of latent heat at a specific temperature, and has the advantages of high energy storage density and approximate temperature. The phase change material is coupled to the end of the capillary mesh, which can store capillary net cooling / heat, alleviate the problem of energy supply and demand, and can reduce the cooling / thermal cost. If the air source heat pump capillary network radiation cooling / heat system, the phase change material can be regenerated / hot during the low ...
