Water-cooled Screw Chiller

Description:
The high-efficiency water-cooled screw chiller is designed with advanced semi-enclosed dual-screw compressor, R134a eco-friendly refrigerant and vertical oil separator, making this chiller with stable performance, high efficiency, and energy saving.

Application:
This water-cooled screw chiller can be used as the cooling system for office buildings, hospitals, schools, shopping centers and production processing.

Features:
1. Semi-closed Dual Screw Compressor for High-efficiency Unit
● This compressor is designed for the water-cooled screw chiller according to actual pressure ratio, with good matching, reducing the over compression and insufficient compressor during the operation of compressor, thus enhancing system energy efficiency. 
● Self-developed efficient rotor type line (patent No.: CN201120008270.9), interdigitating gap is optimized, connection cable is short and the efficiency is even higher. 
● Three-level combined built-in oil separator, the efficiency is over 99.7%, making the system more stable with less noise. 
● The closed motor to avoid refrigerant leakage, built-in PTC temperature protector for the motor, effectively detect motor winding temperature

2. Flooded-type Evaporator 
Refrigerant is evenly distributed in the evaporator. With a flooded type evaporator, evaporation temperature is increased and so is the heat exchange efficiency. Together with a screw compressor that is specialized for flooded type chiller, the unit’s cooling capacity and energy efficiency ratio is greatly improved. COP can reach 6.2.2.
