Wuhan - Double 85 Test Chamber Specifications:

The function of the touch switch in the experimental box

● Light touch switch is mainly used for functional operation keys on the panel. The physical shape and circuit markings of the tactile switch indicate whether the malfunction of the tactile switch is due to poor opening or operation. When pressing the touch switch, use a multimeterrxinThe resistance value between the pin terminals of the gear detection tactile switch can determine whether it is normal. The resistance value of a normal tactile switch is when it is turned ono

The function and composition of the inductor in the experimental box

Inductance is a reactive device, and its main functions in circuits are choke, filtering, tuning, delay, compensation, etc.

Winding a wire around a magnetic core is an inductor, and an air core coil is also an inductor. Inductors come in various shapes and sizes, some of which have a large volume and are easily recognizable from their appearance?A judgment.But some inductors have shapes similar to resistors and capacitors, making it easy to make mistakes. Inductance using letters'L”Performance, common inductor physical objects and inductor markings.

Wuhan-Double 85 Test Chambercharacteristic:

To ensure the cooling rate and minimum temperature requirements of the test chamber, the design of the cooling system should include energy regulation technology. An effective solution is to ensure that the test chamber adopts a two-stage cascade refrigeration system, which includes a high-pressure refrigeration cycle and a low-pressure refrigeration cycle,The connecting container is an evaporative condenser, which functions to use the low-pressure circulating evaporator as the high-pressure circulating condenser. Under normal operation of the refrigeration unit, it can effectively regulate the energy consumption and cooling capacity of the refrigeration system, reducing the operating costs and failure rate of the refrigeration system to a more economical state

● Adopting air-cooled coil condenser and finned multi-stage evaporator, the main refrigeration accessories and control components are imported, such as Danish "Danfoss" thermal expansion valve and American "Aigo" drying filter; Italian "Castello" solenoid valve

Double 85 (85) wet freezing test chamberOptimized refrigeration system:

The refrigeration system adopts an optimized design combination of imported compressors, with lower operating noise and superior performance,Stable and reliable.

The controller automatically adjusts the cooling circuit based on demand to ensure the normal suction and discharge temperature of the compressor and improve its lifespan.

The refrigeration system adopts a new refrigerant demand algorithm, which can reasonably and effectively utilize the refrigeration capacity, effectively reduce the consumption of cold and heat, and achieve stable control and energy-saving effects, saving compared to the same period last year30%above.
