Year-round utilization of phase change energy storage room combining active and passive

Abstract

The invention provides an active and passive combined annual phase-change energy storage room capable of being used all year around, wherein the energy storage room aims to enable a building applying phase-change materials to operate in an energy-saving mode, enable the wall body of the building to adjust the air in a room all year around and extract natural cooling capacity actively, improve the storage and efficiency, heat storage and discharge and heat storage efficiency and cooling efficiency of a phase-change wall board and improve the air quality in the room and the indoor comfort. The active and passive combined annual phase-change energy storage room capable of being used all year around comprises a roof lighting room body, a phase-change combined wall body, a water system and a ventilation system. The roof lighting room body comprises a wall body with the four light-proof faces and a light-transmitting roof for collecting light. The phase-change combined wall body comprises the phase-change wall board, mortar made of phase-change materials, a capillary network, a glass cover plate, an air flue and air inlet. The water system comprises a water cooling and heating device, a water storage device and a tail end device. The ventilation system comprises an air supply device, the air flue, the air opening and a corresponding sealing device. By means of the scheme, great significance is provided for increase of the utilization rate of new resources and the phase-change materials in the building.

Description

technical field [0001] The invention belongs to the technical field of energy utilization, and more specifically relates to an active and passive phase-change energy storage room for year-round utilization. Background technique [0002] In the field of construction, the need for a building material or building energy storage system that can store a large amount of heat to slow down indoor temperature fluctuations and release the stored heat in a timely manner has become an important direction of building energy conservation research. The application of phase change walls has increasingly become a research hotspot in the field of energy conservation. [0003] When the phase change material stores and releases heat in the phase change interval, its latent heat release is significantly greater than the sensible heat release of ordinary materials. It is mixed with traditional building materials to make phase change wall panels and used as building walls. In summer, it can reduc...
