The working principle of refrigerant air dryer is to use the refrigeration principle to evaporate the water in the air or cloth, which is cooled down by the compressor and then passes through the drying basket. The temperature difference between the outside air and the drying basket provides thermal energy to expand the drying material. After drying, the air or cloth can be dried out and reused.
There are two types of refrigerant air dryer: directly cooled type and indirect cooled type. The directly cooled type uses a direct cooling method, which uses the refrigeration principle to directly cool the air or cloth. The indirect cooled type uses a secondary refrigeration system to cool down the air or cloth, which is then passed through the drying basket to achieve the drying effect. Both types of refrigeration air dryer require certain refrigeration equipment and skills, but the direct cooling method has better energy efficiency and environmental protection.
