The high and low temperature alternating humidity test chamber and the constant temperature and humidity test chamber are similar products, but with different names. The high and low temperature alternating humidity test chamber is an essential testing equipment in aviation, automotive, home appliances, scientific research and other fields, used to test and determine the parameters and performance of electrical, electronic and other products and materials after high temperature, low temperature, alternating humidity or constant temperature tests.

Reliability: Large scale alternating wet heat temperature and humidity test room, factory direct sales

The refrigeration cycle adopts the inverse Caryol cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor, consumes work to increase the exhaust temperature, and then the refrigerant exchanges heat with the surrounding medium through the condenser isothermal, transferring heat to the surrounding medium. After the refrigerant undergoes adiabatic expansion through the shut-off valve, the temperature of the refrigerant decreases* The refrigerant absorbs heat from objects with higher temperatures through the evaporator, causing the temperature of the cooled object to decrease. This cycle repeats itself to achieve the purpose of cooling. The design of the refrigeration system applies energy regulation technology, which is an effective way to ensure that the energy consumption and cooling capacity of the refrigeration system can be effectively adjusted under normal operation of the refrigeration unit, reducing the operating costs of the refrigeration system to a more economical state.

The box is processed and formed by CNC machine tools, with a beautiful and elegant shape, and adopts non reactive handles for easy operation.

The inner lining of the box is made of imported high-quality stainless steel (SUS304) mirror panels, and the outer lining of the box is made of A3 steel plate spray painted, which increases the appearance texture and cleanliness.

The water replenishment tank is located at the bottom right of the control box and has automatic water shortage protection, making it more convenient for operators to replenish water sources.

The large observation window is equipped with lighting to keep the inside of the box bright, and uses tempered glass embedded in the heating body to observe the condition inside the box clearly at any time.

Separating the humidification system pipeline from the control circuit board can prevent malfunctions caused by water leakage in the humidification pipeline and improve safety.

The waterway system, pipeline, and circuit system are easy to maintain and repair.

The insulation of the box is made of ultra-fine glass fiber insulation cotton, which can avoid unnecessary energy loss.

There is a 50mm diameter test hole on the left side of the box, which can be used for external testing power or signal lines.

The controller operation interface is available in both Chinese and English, and the real-time operation curve chart can be displayed on the screen.

It has a capacity of 120 sets of programs, 12000 segments, and 999 loop steps, with a maximum time setting of 99 hours and 59 minutes per segment.

After inputting the data and experimental conditions, the controller has a screen lock function to avoid manual touch and shutdown.

It has the function of automatic calculation, which can immediately correct the temperature and humidity change conditions, making temperature and humidity control more accurate and stable.

Freezing and air circulation system.

The refrigeration unit adopts the original French "Taikang" fully enclosed compressor.

The refrigeration system adopts a unit or binary low-temperature circuit system design.

Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, can make the temperature and humidity distribution in the testing area uniform.
