The working part of the test chamber:

Compressor condensing part:

Refrigeration system: The core of the refrigeration system is the compressor. In this plan, we use a French Taikang fully enclosed compressor to ensure the cooling requirements of the studio.

The design of the refrigeration system uses energy adjustment technology. An effective treatment method can not only ensure that the refrigeration system is in normal operation, but also can adjust the energy consumption and cooling capacity of the refrigeration system, so that the operation cost and failure of the refrigeration system The rate dropped to a more economical state.

Lighting system:

The illumination system is mainly composed of xenon lamp tube, lampshade, xenon lamp trigger and various control devices. The energy compensation of the xenon lamp is achieved by adjusting the distance of the sample frame and adjusting the voltage and current.

Air duct system:

The air duct system is located in the mezzanine at the back of the test box, and the heater, fan blades, evaporator, PT100 temperature sampling sensor and other devices are distributed in it. When the fan rotates at a high speed, the air in the working room is sucked into the air duct from the lower part, and the heat generated by the heater and the cold generated by the evaporator are fully mixed in the air duct and blown out from above, and heat exchange with the sample in the working room The latter air is then sucked into the air duct for mixing; it is circulated repeatedly to achieve the target temperature requirement, and at the same time to ensure that the test box obtains a higher temperature and humidity index.

Refrigeration/dehumidification system:

The world-famous French "Taikang" fully enclosed industrial refrigeration compressor is selected. Mainly used to keep the temperature in the working room and reduce the humidity in the working room

Humidification part:
