Many people in laboratories, processing workshops, etc. have some ideas about this. In order to ensure high quality and high yield, the ambient temperature and humidity must be strictly controlled. Therefore, a constant temperature and humidity machine in the laboratory is needed, which is an infrastructure for quality control and cargo inspection. Therefore, it is particularly important to install a constant temperature and humidity machine in the laboratory. So which systems are usually combined with a constant temperature and humidity machine? Next, let's explain it by the editor of the constant temperature and humidity machine.

1. Refrigeration unit

The refrigeration system is one of the important components of the equipment. The refrigeration system consists of two parts, the hot part and the cold part, each of which is a refrigeration system.

The refrigerant in the high temperature section evaporates and absorbs heat from the refrigerant in the low temperature section to evaporate; the refrigerant evaporates in the low temperature section and absorbs heat from the object to be cooled to obtain cold energy.

2. Heating system

Compared with the refrigeration system, the heating system is relatively simple. When the temperature of the conditioned air is lower than the required temperature, the computer controller of the constant temperature and humidity laboratory unit turns on the electric heater to heat the air and send it out. Pass the fan to the air conditioner. The room has a heating effect.

3. Control system

The control system is a complex laboratory box, which determines important indicators such as temperature rise rate and laboratory accuracy. The laboratory controller has a large-screen medium temperature LCD display and RS485 interface to realize network monitoring, and the control accuracy can reach ±1℃ and ±5%~10%RH.

4. Moisture-proof system

The humidification system is divided into two sub-systems: humidification and dehumidification.

The humidification method usually adopts steam humidification. That is, low-pressure steam is directly injected into the experimental humidification space. This kind of humidification method has fast humidification speed and more sensitive control, which can easily realize forced humidification when the temperature drops.

When the humidity of the conditioned air exceeds the required value, the compressor starts to cool, and the air is cooled to below the dew point through the evaporator, and the moisture in the air adheres to obtain the dehumidification effect.

5. Air circulation system

The air circulation system usually consists of a centrifugal fan and a motor that drives it to circulate the air in the testing machine.

The above five points are all about the main systems included in the constant temperature and humidity machine. Thank you for your understanding and support!
