AI Technical Summary

Problems solved by technology

[0005] When the existing artificial climate simulation test chambers simulate the air temperature and humidity, some heating devices, refrigeration devices, humidification devices, and dehumidification devices are directly arranged in the simulation test chamber, but the heating device, refrigeration device, humidification device, dehumidification device The device will open and close frequently due to the triggering of the temperature deviation threshold and the humidity deviation threshold. At the same time, the heating device will retain residual heat after power off, and the refrigeration device and dehumidification device will retain residual cold after power failure. The temperature and humidity control in the simulation test chamber has adverse effects, resulting in unstable and high fluctuations in the temperature and humidity control in the simulation test chamber

[0006] When simulating the temperature and humidity in the existing artificial climate simulation test chamber, some adopt the method of "preparing the gas with the specified temperature and humidity in a specific container outside the simulation test chamber, and then blowing the air through the high-power fan in the simulation test chamber." Turbulent flow, so as to make the temperature and humidity distribution in the simulated test chamber uniform". The blast turbulence of the high-power fan has seriously affected the aerodynamic conditions in the simulated test chamber, making it impossible to conduct univariate research on wind conditions

[0007] Most of the existing artificial climate simulation test chambers only consider the air temperature conditions when simulating the temperature, but do not consider the surface temperature, deep temperature and soil temperature gradient conditions of the underlying soil, and cannot conduct univariate and combined variable studies on the above conditions
