Abstract

The invention provides an environment simulation test box. The environment simulation test box comprises a box body, a humidifier and a pressure release valve; a water vapor outlet of the humidifier is communicated with the box body and is used for adjusting the humidity in the box body; and an inlet of the pressure release valve is formed in the bottom of the box body and used for adjusting the air pressure in the box body. During pressure relief, the inlet of the pressure release valve is located at the bottom of the box body, the amount of air exhausted from the box body is larger than thatof exhausted water vapor, a large amount of water vapor in the box body is prevented from being exhausted, and water vapor loss is reduced, so that the influence of pressure relief operation on the humidity environment in the box body is reduced; the loss of water vapor in the box body is small, and excessive water vapor supplementation is not needed, so that water resources are saved; and the running time and power of the humidifier are also reduced, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of environmental simulation, in particular to an environmental simulation test chamber. Background technique [0002] The high and low temperature humidity test chamber is used to simulate the temperature and humidity test environment. It is mainly composed of five systems: refrigeration system, heating system, humidification system, dehumidification system and control system. When conducting a long-term damp heat test, a large amount of water vapor enters the closed test chamber, which will cause the pressure in the test chamber to rise. If the pressure is not released in time, the water in the wet bulb cup may be pressed out (wet and dry bulb method), or May damage the test chamber. Therefore, a pressure relief device is provided on the test box to balance the internal pressure of the test box. [0003] Found through inventor's research, there is following shortcoming in existing environmental simulatio...
