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.
