AI Technical Summary
Existing drying systems are energy-intensive, and the high-temperature exhaust air cannot be reused, resulting in wasted heat energy. Furthermore, the exhaust air temperature is difficult to control, making energy recovery impossible.
The coating energy-saving drying system uses a heat exchanger in the heat exchange chamber to achieve heat exchange between fresh air and hot and humid return air. It uses a refrigerant circulation channel to recover heat from the hot and humid return air and heats the fresh air through an evaporator and a condenser, forming a near-vertical cross-flow pattern to enhance the heat exchange effect.
It achieves efficient heat recovery and utilization, reduces production costs, reduces energy loss, improves heat exchange efficiency, and ensures stable equipment operation.
