The invention relates to an environmental chamber high and low temperature test ventilation device and ventilation method, the device comprises a front surface air cooler, a rear surface air cooler and an evaporator which are sequentially communicated through a main pipeline, an auxiliary pipeline is arranged between the rear surface air cooler and the evaporator, and the auxiliary pipeline is led into a cab or other equipment positions. The auxiliary pipeline is additionally arranged between the original rear surface air cooler and the evaporator, the temperature of a cab or other equipment positions needing to be cooled or heated is adjusted through the auxiliary pipeline, the structure is simple, and control is convenient. Original refrigeration equipment and fresh air equipment of the environmental chamber are borrowed, an air pipeline ventilation system is additionally arranged on the basis of the original equipment, the development period is short, and the cost is low; under the condition that an air conditioner is not turned on, the temperature of the cab can be adjusted; and the temperature of other equipment positions needing ventilation can be adjusted.
本发明涉及一种环境舱高低温试验通风装置及通风方法,该装置,包括通过主管道依次连通的前表冷器、后表冷器和蒸发器,后表冷器和蒸发器之间设有副管道,副管道通入驾驶室或其它设备位置。通过在原有的后表冷器和蒸发器之间增设副管道,通过副管道对需要进行降温或升温的驾驶室或其它设备位置进行温度调节,结构简单,控制方便。本发明借用环境舱原有的制冷设备和新风设备,在原有设备基础上新增空气管路通风系统,开发周期短,成本低;本发明既能在不开空调的情况下,对驾驶室进行温度调节;又能对其它需要通风的设备位置进行温度调节。
