225L High And Low Temperature Test Chamber Climatic Constant Temperature Humidity Chamber

Jianqiao specializes in the production of environmental and high-frequency vibration tables: test equipment. It is a professional test equipment enterprise integrating R&D, design, production and sales. The high and low temperature  test chamber is mainly used to test the performance of various materials in heat resistance, cold resistance, dry resistance and humidity resistance. The machine uses Chinese and English to display the color touch screen, simple operation, easy program editing, can display the complete system operation status related data, execution and set the program curve. When an abnormal situation occurs during operation, the screen automatically displays the cause of the failure and provides a method for troubleshooting.

The high and low temperature alternating humidity and humidity test chamber is suitable for the reaction conditions of various electronic parts, hardware and home appliances, plastic materials, automobiles, medical, chemical, communications and other industries in the temperature and humidity test environment. It is suitable for temperature and humidity environment testing of product development, design, production, inspection and other departments in various industries.

II. Introduction of the advantages and characteristics of Jianqiao products:

1.Refrigerating system:

All important configurations adopt imported brand components, which are equipped with compressor suction and discharge, temperature, automatic pressure coordination system and high/low pressure sensors. The precise control of the return air superheat ensures that the compressor operates at the design best state under different atmospheric temperatures  to avoid overheating or overcooling of the compressor, to prevent the compressor from liquid shock and other adverse factors, to ensure the life of the compressor and the safety of operation, extend the life of the compressor.

Adopt imported German "Bock" semi-hermetic compressor, American "Honeywell" import environmentally friendly refrigerant, American "Emerson", Denmark "Danfoss", Japan "Saglnomlya", American "Sporlan", Italian "Castor" Refrigeration accessories such as world-renowned brands.

2. Advanced air duct design:

There are multiple air duct design patents ZL2016200952038, research and development and design of environmental testing equipment CFD flow channel optimization simulation simulation system, through advanced air duct design, to ensure the temperature uniformity and fluctuation of the environmental test chamber, and effectively control the frost of the evaporator phenomenon

3. Excellent adjustment method:

The patented PWM cooling control mode (consistent with the first-class European and American manufacturers) can achieve the effect of temperature control through the accurate output of the compressor's cooling capacity. The temperature reduction and temperature maintenance processes below normal temperature do not require heaters to participate, which is completely different from cold Thermal balance temperature control method, that is, heating without cooling, cooling without heating, energy saving of more than 40%

4. Efficient condensing evaporator (plate heat exchanger):

Advantages of plate heat exchanger:

1) Compact structure, small size, weight is only about 25% of the shell and tube heat exchanger with the same heat transfer area

2) The equivalent diameter of the plate heat exchanger is small, the flow disturbance is large, and turbulence can be formed at a small Reynolds number, so the heat transfer coefficient is high, generally 1.5 times that of the shell and tube heat exchanger

3) Small refrigerant charge

The company adopts the world's top Swedish AIFALAVAL plate double cascade brazed heat exchanger in the refrigeration system, which overcomes the shortcomings of the large size, poor heat exchange and low efficiency of this component of the domestic low-temperature equipment.
