The Control system is the core of the constant temperature and humidity chamber

The Control system is the core of the constant temperature and humidity chamber, it determines the temperature rise rate of the text chamber, precision, and other important indicators. Now the controller of the test chamber mostly adopts PID control, but also a few adopts PID and fuzzy control phase combination control mode. Because the control system of the thermostatic oscillator basically belongs to the category of software, and this part in the use of the process, generally there will be no problems.

In the constant temperature and humidity chamber refrigeration principle diagram, we introduced the temperature and humidity chamber refrigeration system several important components of the working path. So how do these components work? The refrigerant is adiabatically compressed to a higher pressure by the compressor, and the work is consumed to raise the exhaust temperature. After that, the refrigerant isothermally exchanges heat with the surrounding medium through the refrigerant cooler, and the temperature is transferred to the surrounding medium. After the refrigerant through the closure valve adiabatic expansion work, then the refrigerant temperature decreases. The refrigerant is cooled by absorbing heat isothermically from a higher temperature object through the evaporator.
