Principle
The test chamber adopts a cascade refrigeration system, which consists of two relatively independent refrigeration systems, the high temperature part and the low temperature part, which are connected by evaporative condenser. The heating system is composed of high-power resistance wire to achieve rapid heating up. The temperature and humidity system is divided into two subsystems of humidification and dehumidification. The humidification adopts steam humidification method, and the dehumidification adopts mechanical refrigeration dehumidification and drying dehumidification. The control system adopts smart microcomputer PID + SSR/SCR automatic forward and reverse bidirectional synchronous output to realize accurate temperature and humidity control.
Applications
Plastics, electronics, food, clothing, vehicles, metals, chemicals, building materials
