Principle
The refrigeration system adopts cascade refrigeration, which is composed of high temperature part and low temperature part. It is connected by evaporation condenser. The high temperature part of the refrigerant evaporates and absorbs the low temperature part of the heat, and the low temperature part of the refrigerant evaporates and absorbs heat from the air in the box. The heating system is composed of high power resistance wire to achieve rapid temperature rise. The temperature and humidity system is divided into humidification and dehumidification subsystem. The humidification adopts steam humidification method. The dehumidification adopts two ways of mechanical refrigeration dehumidification and drying dehumidification. The Sensor system adopts platinum resistance and Thermocouple measurement temperature. The solid state electronic

Steps
1. Set program catalog management and test data
2. Select the operation mode: fixed value/program/link
3. Set the reservation start function
4. Lock the operating conditions to prevent accidental touch
5. Configure the humidification system box water supply, manually add 20L of water each time
6. Place the product on the test rack (load-bearing within 20 kg)
7. Start testing and monitor actual operation Linear dispersion
8. View fault history data when abnormal
Notice
• Power supply voltage must be 220V AC (+/- 10%), protective ground wire, ground resistance ≤ 4Ω
• Do not use knife switches or power sockets, must use air switches (40A)
• The resistivity of humidification water needs to be ≥ 500MΩ
• The load-bearing capacity of the product rack does not exceed 20kg
• Note that safety devices include air burn prevention, high voltage protection, overheating protection, overcurrent protection, Pottery and porcelain E-16 fast fuse, no fuse overload protection
• The frequency needs to be kept at 50 +/- 0.5Hz
• After a power outage, you can choose BREAK (interrupt), COLD (cold engine start) or HOT (hot engine start) mode as needed
