High and low temperature alternating humidity test chamber

refrigeration system

1. Low temperature refrigeration adopts FranceTaikang "fully enclosed compressor unit. Use R404A environmentally friendly refrigerant. Evaporative condenser serves as both a high-temperature evaporator and a low-temperature condenser；

2. To ensure the safe operation of the system, high and low voltage control, overpressure, overload and other protection systems are installed in the system. At the same time, in order to monitor the operation of the system, a high voltage meter must be installed at the high voltage end to monitor the operation of the system；

Heating and humidification system

1. The heater adopts a porcelain frame nickel chromium wire electric heater, which has low thermal inertia and long service life. Can be output by the instrument

Control pulse duty cyclePID signal, controlled by solid-state relay, ensuring smooth and reliable control；

2. Steam boiler electric heating and humidification method, armored electric heating tube,PID control method, using contactless periodic pulse

Adjust the widthSSR (Solid State Relay) control, equipped with water level control device and heater anti dry burning device；

control system：

1. Control system: adopts LCD touch screen temperature controlwetDegree controller, capable of setting values and running programs.

2. Sensor:PT100 temperature sensor；

3. Safety protection measures should be installed in the control system, including phase loss protection, phase sequence error protection, and fan overload protection French Taikang Compressor

Protection, over temperature, power outage protection, unit high voltage protection, unit overload protection, unit over temperature protection, leakage protection, etc；

• In addition to the main controller, an independent overtemperature protector is also installed in the system. Even if the main controller fails, the overtemperature protector can reliably disconnect the heating power supply to protect the safety of the equipment and test samples；
