 The design of the refrigeration system applies energy regulation technology. An effective treatment method can not only ensure the normal operation of the refrigeration unit, but also regulate the energy consumption and cooling capacity of the refrigeration system, so that the operating cost and failure rate of the refrigeration system can be reduced to a more economical state.

Air duct system:

 The air duct system is located in the interlayer at the back of the test box, and the heater, fan blade, evaporator, PT100 temperature sampling sensor and other devices are distributed in it. When the fan rotates at high speed, the air in the working chamber is sucked into the air duct from the upper part, and the heat generated by the heater and the cold quantity generated by the evaporator are fully mixed in the air duct and blown out from the lower part. The air after heat exchange with the test object in the working chamber is then sucked into the air duct for mixing; Repeat the cycle to meet the target temperature requirements, and ensure that the high temperature and humidity indicators are obtained in the test chamber.

Gas circulation part:

 Built-in circulating air duct and ventilator, efficient refrigerator and energy regulation system are used, and effective heat exchange is achieved through efficient ventilator to achieve the purpose of temperature change. By improving the air blast flow, the air flow and the heat exchange capacity of heating and humidification and air surface cooler are improved, and the temperature and humidity uniformity of the test chamber is greatly improved through the adjustment of adjustable air plug at the air outlet;
