Problems solved by technology

[0006] At present, the external spray humidification is mainly used, and the humidification is realized by splitting and mixing. Although the influence of refrigeration on air humidity is reduced, the air entering the artificial box from the external humidifier does not pass through the temperature adjustment device of the artificial climate box. The control accuracy of the air temperature is reduced, and the recycling of water cannot be realized, and the water consumption is greatly increased
[0007] The built-in humidifier realizes water recycling, but when the humidified air passes through the evaporating tube, the moisture in the air is easily condensed into liquid water by the evaporator, reducing the humidification effect
In the middle and high temperature area, the built-in humidifier can work normally, but in the low temperature area, when the temperature of the air entering the humidifier is lower than 0 degrees, the water will freeze, which will affect the normal operation of the humidifier and reduce the humidification performance

Description

technical field [0001] The invention relates to a split flow internal humidification type environmental box. Background technique [0002] Constrained adjustable uniaxial temperature-stress testing machine is a kind of equipment for studying the early hydration characteristics, stress development, deformation modulus and creep of concrete. The environmental chamber is an important device on the constrained adjustable uniaxial temperature-stress testing machine, and it is a device that can simulate the external natural environment. Because the deformation and cracking of concrete specimens are related to the temperature, humidity and wind speed of the air in the external natural environment. The environmental chamber simulates the temperature, humidity and wind speed of the air in different natural environments to quantitatively analyze and evaluate the sensitivity of various natural environments to the deformation and cracking of concrete specimens. [0003] At present, on...
