Multi-stage radiation phase change wall adopting air source heat pump system

Abstract

The invention discloses a multi-stage radiation phase change wall adopting an air source heat pump system. The multi-stage radiation phase change wall comprises the air source heat pump system and a multi-stage radiation phase change wall pipeline circulating system. The wall specifically comprises a multi-stage radiation phase change wall body, a compressor, a four-way valve, an outdoor air-cooled heat exchanger, a high-pressure liquid reservoir, a drying filter, an electromagnetic valve, a refrigeration thermostatic expansion valve, a heating thermostatic expansion valve, a water-cooled heatexchanger, a gas-liquid separator, a water storage tank, a circulating water pump, a three-way valve, a multi-stage radiation phase change wall body and an electric heater. The multi-stage radiationphase change wall and the air source heat pump system thereof utilize valley price electricity at night to store heat energy in the multi-stage radiation phase change wall, the stored heat is releasedin the daytime, and the electric heater is combined to serve as an auxiliary heating device to provide domestic hot water. By means of the peak-valley electricity price difference, the problem that energy supply and demand are not matched is solved, meanwhile, energy consumption is reduced, and the thermal comfort degree of a room is improved.

Description

technical field [0001] The invention relates to a phase-change energy-saving wall body, in particular to a multi-stage radiation phase-change wall body using an air source heat pump system. Background technique [0002] Among the insulation walls proposed in recent years, most of them still use the method of increasing the heat transfer resistance of the envelope structure to reduce the dissipation of indoor heat. Adding phase change materials to the enclosure structure can effectively improve the thermal insulation performance of the wall. In addition, it can improve the heat storage performance of the building, increase the thermal inertia of the enclosure structure, increase the surface temperature of the enclosure structure, and reduce the radiation heat dissipation of the human body. The level of comfort has been improved, and therefore more and more attention has been paid to it. The development of phase change heat storage wall is still in the initial research stage....

AI Technical Summary

Problems solved by technology

Most of the existing phase-change thermal storage walls only add phase-change materials to the wall, which cannot effectively transfer and store heat. The form is single and the degree of improvement in comfort is limited.

In addition, it has not been possible to couple the phase change heat storage wall with the energy system to make efficient use of energy
