Pressure-adjustable hollow building envelope and operation method thereof

Abstract

The invention provides a pressure-adjustable hollow building envelope and an operation method thereof. The hollow building envelope comprises an inner surface cover plate, an outer surface cover plate, an upper cover plate, a lower cover plate, a hollow layer, a vacuum pump connector, a vacuum pump, an air compressor connector, an air compressor, supporting mechanisms, micro fans, an indoor temperature sensor, an outdoor temperature sensor, a pressure sensor and a central controller, wherein the inner surface cover plate is provided with the vacuum pump connector and the air compressor connector, the vacuum pump connector is connected with the vacuum pump, and the air compressor connector is connected with the air compressor; the supporting mechanisms and the micro fans are arranged in the hollow layer, and the central controller is connected with the vacuum pump, the micro fans, the indoor and outdoor temperature sensors, the air compressor and the pressure sensor. For a building with the cooling load all year round, a vacuum mode and a pressurization mode are switched according to temperature changes, i.e., in summer, the hollow layer is vacuumized to achieve the vacuum insulation effect, and in winter, the air compressor presses air into the hollow layer, the fans are started to increase the indoor and outdoor heat exchange amount, and natural cold sources are fully utilized.

Description

technical field [0001] The invention relates to a pressure-adjustable hollow building enclosure structure and an operation method thereof, belonging to the technical field of building energy saving and air conditioning. Background technique [0002] At present, the energy consumption of indoor air-conditioning equipment occupies a considerable proportion in the total energy consumption of buildings; indoor air-conditioning equipment uses special means to adjust and improve the air in buildings to create the most suitable indoor environment for people to work and live in. The energy consumption of air-conditioning depends on the indoor load of the building, and the place with the largest load in the air-conditioned area is the air-conditioned room that is in direct contact with the external environment. Since outdoor air invades the room through convection and heat conduction, it will undoubtedly greatly increase the indoor air-conditioning load. For ordinary buildings in win...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem of effectively reducing the energy consumption of building air-conditioning equipment in buildings with cooling loads throughout the year, the present invention provides a pressure-adjustable hollow building envelope and its operating method, which can prevent the heat load from the external environment from being introduced in summer In the interior of the building, the heat transfer process between the interior of the building and the external environment can be effectively reduced; in winter, the cooling load of the external environment can be accelerated into the interior of the building, and the heat transfer process between the interior of the building and the external environment can be strengthened, thereby reducing the indoor temperature. The purpose of reducing the load of air-conditioning equipment and reducing building energy consumption
