Overall structure

The high and low temperature impact test chamber is automatically controlled by instruments to switch between high and low temperature air valves, forming a closed-loop air circulation system with the high temperature chamber or low temperature chamber, and quickly reaching the target temperature of the test.

The temperature state inside the high and low temperature impact test chamber is determined by the working status of the heater, evaporator, and fan in the air duct. The experimental chamber adopts a forced axial flow "dispersion" loop wind working method, which can greatly improve the fluctuation, uniformity and other parameters of equipment operation.

temperature control

It can be achieved by setting the controller to the desired temperature. The controller controls the heater or refrigerator to raise or lower the temperature of the heat storage or low-temperature chamber to the desired value and maintain it at this temperature. During the experiment, By controlling the opening and closing of the air door, the hot air from the high-temperature chamber and the cold air from the low-temperature chamber are directed into the test area, and their status is displayed on the controller.
