A thermal storage type controllable dual-channel ventilation insulation wall system and its operation method

Abstract

The invention provides a heat storage type controllable double-channel ventilation heat preservation wall system and an operation method thereof, and belongs to the technical field of passive building energy conservation. The heat storage type controllable double-channel ventilation heat preservation wall system and the operation method thereof are characterized in that double air channels with a phase change heat storage function are arranged, controllable air valves are arranged on the upper sides and the lower sides of the channels, and flexible conversion between a ventilation wall and an air heat preservation wall is completed by controlling the air valves, so that ventilation and heat preservation functions of a building are achieved. The heat storage type controllable double-channel ventilation heat preservation wall system comprises a glass cover plate, the two channels, a heat-absorbing material layer, a phase change heat storage material layer and the multiple controllable air valves, and the heat-absorbing material layer and the phase change heat storage material layer are arranged between the two channels. When the controllable air valves on the upper sides and the lower sides of the channels are opened, the natural ventilation wall is formed. When the controllable air valves on the upper sides and the lower sides of the channels are closed, the air heat preservation wall is formed. The controllable air valves are controlled according to the indoor and outdoor temperature and humidity parameters and the change of solar radiation, and conversion between the air heat preservation wall and the natural ventilation wall is achieved, so that coordinated operation of the heat storage type controllable double-channel ventilation heat preservation wall system and the operation method thereof, the building structure and the outdoor climate is achieved.

Description

technical field [0001] The invention relates to a thermal storage type controllable dual-channel ventilation insulation wall system and its operating method, which belong to the technical field of passive building energy saving, and specifically relate to a dual-channel with phase change heat storage, and controllable air valves are arranged on the upper and lower sides of the channel , and through the control of the air valve to complete the flexible conversion between the natural ventilation wall and the air insulation wall, so as to realize the system of building ventilation and insulation functions. technical background [0002] With the development of society and the improvement of people's requirements for quality of life, building energy consumption is increasing, of which energy consumption for HVAC accounts for 50% of the total energy consumption of buildings. In the background of world energy shortage and serious pollution of fossil energy Under the current situati...

Problems solved by technology

[0004] Solar radiant heat is affected by seasons and day and night. The traditional single-function passive Trombe wall system has low adaptability and adjustability to seasonal and day-night changes. At the same time, it does not have heat storage capacity, which restricts the time extension of solar energy utilization. , so a new ventilation and thermal insulation wall system is needed to solve the above problems
