The constant temperature and humidity chamber, as the name implies, is an incubator with temperature and humidity control function to maintain a constant temperature and humidity environment. Constant temperature and humidity chambers are used in many industries, and the application purposes will be different in different industries. In the agricultural field, the constant temperature and humidity chamber is mainly used for breeding seedlings, and researching the heat resistance, cold resistance, dry resistance and moisture resistance of seeds or plants under various environments.

The constant temperature and humidity chamber can complete the precise temperature and humidity control work, and maintain the constant temperature and humidity culture environment for a long time, mainly relying on the cooperation of several major systems. Therefore, to understand the constant temperature and humidity chamber, it is necessary to understand the constant temperature and humidity. The main system of the box, the following is a brief introduction.

1. Refrigeration system: The refrigeration system is one of the key parts of the constant temperature and humidity chamber. It is mainly composed of compressor, condenser, throttling mechanism and evaporator. The refrigeration system of constant temperature and humidity chamber is composed of two parts, which are called high temperature. Part and low temperature part, each part is a relatively independent refrigeration system.

2. Heating system: The heating system is mainly composed of high-power resistance wire. Because the temperature rising rate required by the constant temperature and humidity chamber is large, the heating system power of the test box is relatively large, and the heater is also provided on the bottom plate of the test box.

3. Humidity system: The temperature system is divided into two subsystems: humidification and dehumidification, which can realize humidification and dehumidification functions respectively. It has the advantages of strong humidification and dehumidification ability, fast speed and sensitive control.

4. Control system: The control system is the core of the integrated constant temperature and humidity chamber, which determines the important parameters such as the heating rate and accuracy of the test chamber. Most of the controllers in the test box now use PID control, and a small number of control modes that combine PID and fuzzy control.

5. Sensor system: The sensor is mainly a temperature and humidity sensor, which is used to measure and record the temperature and humidity environment in the incubator.

6. Air circulation system: also called air circulation system, which provides circulation of air in the test chamber.

The above is the main system introduction of constant temperature and humidity chamber. If you need more detailed information about this product, please contact us.
