3. Double layer silicone rubber sealing material is adopted for gate sealing.

4. The observation window is made of toughened insulating glass with multi-layer conductive film, and the size is 200×300mm. In order to prevent frosting in the glass at low temperature, a special built-in heating wire surround is specially designed, and a light is provided to provide illumination for observation.

5. In the side of the box with a plug with 50mm test hole, plug material for silicone rubber low foam, can withstand high and low temperature, with heat preservation efficiency.

6. An air conditioning cabinet is set at the back of the box office, in which evaporator, electric heater, humidifier, fan, fan volute and other equipment are installed.

7. The temperature sensor is placed in the outlet.

8. The air supply mode in the test box is upper air supply and lower air return mode.

5. Refrigeration system

1. French "taikang" fully enclosed compressor unit is adopted for cryogenic refrigeration.Other refrigeration components, such as DANFOSS, CASTEL and other imported brand products.Use R404A environmental friendly refrigerant.Evaporative condenser is used as both high temperature evaporator and low temperature condenser.

2. In order to ensure the safe operation of the system, it is necessary to set protection systems such as high-voltage control, overvoltage and overload.Meanwhile, in order to monitor the operation of the system, a high pressure meter is set up at the high pressure end to monitor the operation of the system.

3. Cooling capacity adjustment adopts shunt method.

Heating and humidifying system

1. The heater adopts nickel-chromium wire electric heater with porcelain frame, which has small thermal inertia and long service life.Output by meter

Controllable pulse duty ratio PID signal is controlled by solid state relay, which is stable and reliable.

2. Steam boiler electric heating and humidification method, armored electric heating tube, PID control mode, non-contact periodic pulse width adjusting SSR (solid state relay) control, water level control device, heater anti-dry burning device.

Control system

1. Control system: the LCD touch screen temperature and humidity controller and schneider electric components constitute the electrical control system.
