A multi-stage radiation phase change wall using an air source heat pump system

Abstract

The invention discloses a multi-stage radiation phase change wall adopting an air source heat pump system, which comprises an air source heat pump system and a multistage radiation phase change wall pipeline circulation system. Specifically including multi-stage radiation phase change wall, compressor, four-way valve, outdoor air-cooled heat exchanger, high-pressure liquid receiver, dry filter, solenoid valve, cooling thermal expansion valve, heating thermal expansion valve, water-cooled heat exchange device, gas-liquid separator, water storage tank, circulating water pump, three-way valve, multi-stage radiation phase change wall and electric heater. The multi-level radiation phase change wall and its air source heat pump system use the valley price electricity at night to store heat energy in the multi-level radiation phase change wall, release the stored heat during the day, and combine electric heaters as auxiliary heating The unit provides domestic hot water. The invention solves the problem of mismatch between energy supply and demand by utilizing the difference in peak and valley electricity prices, reduces energy consumption, and improves the thermal comfort of the room.

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
