Cooling system The refrigeration system: composed of a semi-hermetic low-temperature compressor. The compressor has the characteristics of compact structure, low vibration, low noise, high energy efficiency ratio, and large cooling capacity under low temperature conditions. The optimized design of the refrigeration system reduced operating costs and increased reliability.
Compressor cooling method: water-cooled
Air ventilation The centrifugal fan sends air horizontally, and adopts the design of left and right air outlet and middle return air. It is most suitable for the aging of test items in the room, which can effectively take away the heat of the test items themselves. The wind speed and wind pressure meet the test standards, and the temperature stabilizes quickly at the moment of opening and closing the door, ensuring uniform indoor temperature.

Door Electric door 120 x 210(WxH) CM
safety Gate Escape Gate (90 x 210)CM
Pressure balance control valve with inner and outer box
Window Multi-layer vacuum glass window W400*H700mm
Control panel Temperature controller, control power switch, (operation, test termination, over-temperature) three-color status indicator, buzzer, exhaust indicator, lighting switch, over-temperature protector, three-phase current indicator, voltage indicator, Voltage changeover switch, etc.
The installation position of the control panel varies with the installation position of the door; the three-color indicator light can be installed separately in crowded areas, so that the relevant personnel can react quickly when the laboratory alarms.(The specific position of the control panel and the three-color indicator light is based on the design drawing)
Power distribution control cabinet Cooling fan switchboard
Main power air switch
The electrical control design refers to the " Design of Low-Voltage Power Distribution" GB50054-95, " Design of Power Supply and Distribution" GB50052, "Construction and Acceptance of Grounding Devices of Electrical Installation Engineering" GB50169-92

All electronic control components and circuits are equipped with markings and wire numbers to standardize electrical assembly and facilitate inspection and maintenance:
Heating System Finned radiator tube nickel-chromium alloy U-shaped high-efficiency heater, automatic calculation of high-precision PID+SSR control (calculation cycle: 1~4S can be set), so that the heat loss is equivalent to the heating capacity, Heater control mode: non-contact and other periodic pulse width adjustment, SSR (solid state relay)
Control system 7-inch color touch screen with Chinese/English display + German Siemens control module. The controller adopts LCD color touch screen, and the control system adopts man-machine dialogue; it has an automatic, intelligent and humanized design. The control system adopts a two-way input and two-way output control mode to control the temperature, and can display the operating time, the working status of the heater, the refrigeration unit, and the fan. The heating system, refrigeration system, circulation fan and other subsystems can be automatically combined to ensure the high control quality of the entire temperature control system; the control system also has self-detection and self-diagnosis functions, and automatically displays faults and alarms.
RS-232 communication interface software. The system software is designed based on the Windows platform, and has a wide range of adaptability, security, reliability and advancement with other software and hardware. The display screen can directly display and set various operating parameters, operating time, working status of the refrigeration unit and heating system.
