Active and passive convection and radiation heat exchange interior wall system based on phase change energy accumulation

Abstract

The invention provides an active and passive convection and radiation heat exchange interior wall system based on phase change energy accumulation. The system comprises a heat accumulation interior wall body, an active and passive ventilation system, an active capillary net energy accumulation system, a heat insulating layer and an exterior wall body, wherein the interior wall body comprises an interior wall surface decoration material layer and an interior wall phase change energy accumulation plate; the active and passive ventilation system comprises a ventilation cavity, an upper air port, a lower air port, a silent fan and a windproof fin; the capillary net system consists of a main water supply pipe, a main water return pipe and a branch pipe net; the heat insulating layer comprises a heat insulating layer I and a heat insulating layer II, and is attached on the inner surface of the exterior wall body; and the inner surface of the heat insulating layer I is attached with an exterior wall phase change energy accumulation plate. The system uses the heat accumulating and releasing capacity of phase change heat accumulation wall bodies more fully and reasonably, and promotes the heat comfort of indoor environment.

Description

technical field [0001] The invention belongs to the technical field of heat storage and ventilation of phase change materials, and in particular relates to an active and passive convection and radiation heat exchange inner wall system based on phase change energy storage. Background technique [0002] In recent years, building energy consumption accounts for an increasing proportion of total energy consumption. Compared with existing energy-saving technologies, phase change energy storage technology is a latent heat storage technology. Phase change materials can store certain forms of energy under specific conditions and release them under specific conditions. This feature can effectively slow down fluctuations in indoor temperature and keep the temperature within the comfort zone of the human body. At present, the application of phase change materials in the field of building energy saving is mainly reflected in two aspects: one is passive energy saving, which makes full us...

Problems solved by technology

[0004] At present, there are many related technical documents on the coupling of phase change materials and interior walls, but most of them are limited to passive adjustment. Even if active systems are considered, many studies cannot be effectively coupled with interior wall systems.
