Page 5: Features
Water-Cooled ducted unit uses water as the cooling medium Energy Saving which has higher efficiency than air. Simultaneous cooling and High can be achieved through water loop system, providing Efficiency comfort and cost saving all year round. Energy can be transferred easily in the system providing excellent solution to diversity effect. -
Page 6: Cooling Cycle
Water-Cooled Ducted Unit Working Principles Outdoor Unit Indoor Unit Cooling Operation Refrigerant Pipe Cooling cycle High pressure refrigerant is discharged from compressor to tube-in-tube heat exchanger. Functioning as a condenser, the tube-in-tube heat exchanger cools down the refrigerant through cool water supplied from cooling tower. Water temperature will rise about 5~6°C. -
