High-efficiency Modular Air-cooled Screw Chiller

Special Flooded Screw Compressor

A. Apply special motor that can be up to Grade F with thermostability of 155°C.

B. No speed-up gear mechanism design: twin screw compressor adopts direct-connected driving motor for reducing driving efficiency loss and for a more compact structure;

C. Motor of compressor is cooled down through diluent cooling of gas-absorbing cavity to lower the temperature of motor, and ensure diluent cooling of refrigeration oil. Through which can prevent decrease of insulativity due to high temperature of motor, otherwise the motor will be burnt.

Gree Self-developed High-efficiency Vertical Oil Separator

Adopt external oil separator design, apply four stage (rotate separation, collision, natural sedimentation, filter separation) separating technology to ensure adequate filtration of refrigeration oil discharged from compressor, and prevent the refrigeration oil from leaking into the system. The actual measurement efficiency of oil separation is up to 99.97%.                   

High-efficiency and Energy-saving

Flooded shell and tube design: adopt TURBO-BII ultra high efficiency evaporator that the evaporating pipe is soaking in liquid refrigerant for improving heat transfer capacity and cooling efficiency, the evaporating temperature is higher than 5.5℃; chilled water pass through the tube for re-ducing flowage pressure loss of water side and reduce energy consumption of water pump. This evapo-rator works with the high-performance and reliable special screw compressor, which can greatly improve cooling capacity and energy efficiency ratio of unit.

High Comfort Level:

Ultralow temperature cooling design *(optional): Apply control technology of inverter fan unit to conduct reliable cooling under the ambient temperature of -20℃.
