The invention discloses a building wall heat, humidity and air coupling transmission characteristic testing device and method and belongs to a building wall heat and humidity coupling transmission testing device and method. A static pressure box with an opening formed in one side is installed on one side of a tested building wall in a sealed mode, an air inlet of the static pressure box is flexibly connected with an air outlet of a draught fan, temperature and humidity sensors are arranged in a wall and on the surface of the other side of the wall, a temperature, humidity and pressure sensor is arranged in the static pressure box, and temperature, humidity and pressure signals are transmitted to an acquisition module which is connected with a computer through a signal transmission line. Air ports of the static pressure box include adjustable air outlets and the air inlet provided with a multi-blade adjusting valve. Temperature, humidity and air pressure are transmitted to the computer through the acquisition module, and the temperature and humidity distribution condition in the wall under different pressure differences is displayed, stored, recorded and monitored through online monitoring software. The method is easy and convenient to execute, testing accuracy is high, the method can be widely used for measuring the temperature and humidity field distribution of the building wall in the heat, humidity and air multi-field coupled transmission process.
Description
technical field [0001] The invention relates to a device and a method for testing the heat-humidity coupling transfer characteristics of a building wall, in particular to a device and a method for testing the heat, humidity and air coupling transfer characteristics of a building wall. Background technique [0002] The building envelope is a component that constitutes the building space and resists the adverse effects of the environment. With the increasing awareness of global sustainable development and energy conservation and emission reduction, the building envelope has once again become the focus of attention. About 60% of building energy consumption is heating and air-conditioning energy consumption, which is the largest part of building energy consumption. Among them, the heat consumption of building envelope accounts for more than 1 / 3 of building heating and air-conditioning energy consumption. Rational design and selection of building envelope types and components is...
