The operating principle of a refrigerated dryer is based on the relationship between the amount of water vapor in compressed air and its temperature. By lowering the compressed air temperature while maintaining a relatively stable pressure, the water vapor content can be reduced, and the excess water vapor condenses into liquid. A refrigerated dryer utilizes this principle, using refrigeration technology to dry compressed air.
Thus, a refrigerated dryer is equipped with a refrigeration system, which falls under the category of compression refrigeration and comprises core components such as a compressor, condenser, evaporator, and expansion valve. These components are connected by pipes to form a closed loop system. Within the system, the refrigerant continuously circulates, undergoing phase changes and exchanging heat with the compressed air and cooling medium, thereby achieving drying.
Compressed air dryers also include various types, such as adsorption dryers and dissolution dryers.
