working principle

　　

1. The constant temperature and humidity test chamber consists of two parts: temperature control (heating, cooling) and humidification. By installing a rotating fan at the top of the box, air is discharged into the box to achieve gas circulation and balance the temperature and humidity inside the box. The data collected by the temperature and humidity sensors built into the box is transmitted to the temperature and humidity controller (micro information processor) for editing and processing, and temperature and humidity control instructions are issued. This is achieved through the joint operation of the air heating unit, condenser tube, and water tank heating and evaporation unit.

2. The temperature regulation of a constant temperature and humidity box is achieved by using a built-in temperature sensor to collect data, which is then controlled by a temperature controller (miniature information processor). The air heating unit is connected to increase the temperature or the refrigeration solenoid valve is adjusted to lower the temperature inside the box, in order to achieve the desired temperature for control. The temperature regulation of a constant temperature and humidity chamber is achieved by using a built-in temperature sensor to collect data, which is then controlled by a humidity controller (miniature information processor). The heating element of the water tank is connected, and the humidity inside the chamber is increased by evaporating the water in the tank or adjusting the cooling solenoid valve to achieve dehumidification, in order to control the required humidity.

3. The constant temperature and humidity chamber is equipped with multiple protective measures; The temperature system is equipped with an over temperature protector under the maximum safe allowable temperature conditions that can be set. The air heating element can automatically power off when the rotating fan stops; The humidification system can stop supplying power as the water level in the humidification tank decreases; The refrigeration system also stops working as the temperature of the box rises (over 40 ℃) or the humidity increases.
