High Light Water cooled screw chiller R134a R513A ，High efficiency HVAC water chiller ，Industrial water chiller with VSD
Water Cooled Screw Chiller R134a R513A VSD 90-550RT
High Efficiency HVAC Industrial Efficiency Meets Commercial Versatility
Product Overview
The Midea Water Cooled Screw Chiller series represents the pinnacle of industrial cooling efficiency combined with commercial versatility. Available in SHWE and SCWG series configurations with R134a or R513A refrigerants, these chillers deliver capacities from 90 to 550RT, meeting the demanding requirements of large-scale commercial and industrial applications.
The semi-hermetic twin-rotor screw compressors feature precision-engineered asymmetric rotor profiles with five teeth engaging six teeth at micron-level accuracy. SKF bearings ensure 50,000 hours of continuous operation, while variable speed drive options enable infinite capacity modulation through sliding valve technology.
With COP values reaching 5.55 and IPLV performance up to 7.26, these chillers excel in applications requiring both full-load and part-load efficiency. The flooded evaporators with liquid distribution and baffle plates optimize heat transfer, while the optimized condensers with enhanced tubes on both sides deliver superior cooling performance.
Core Features
High-Efficiency Screw Compressors
The semi-hermetic twin-rotor screw compressors feature five-tooth/six-tooth asymmetric rotor profiles engineered to micron-level precision. SKF bearings provide reliable operation for 50,000 continuous operating hours, ensuring long-term reliability in demanding applications.
Variable Speed Drive Options
Available in variable speed full-liquid (SCWG_EV) and fixed-speed full-liquid (SCWG_E) configurations. The VSD models provide stepless capacity modulation, optimizing energy consumption across varying load conditions.
Flooded Evaporator Technology
The flooded evaporators utilize liquid distribution plates and baffle plates to ensure optimal refrigerant distribution. This design maximizes heat transfer efficiency while maintaining stable leaving water temperatures.
Optimized Condenser Design
Condensers feature enhanced tubes on both refrigerant sides, integrated oil separators, and subcooling sections. This comprehensive optimization ensures superior heat rejection and system efficiency.
Three-Stage Oil Separation
The advanced oil management system incorporates three-stage oil separation technology. Combined with dual return oil systems and Venturi ejector technology, this design ensures reliable compressor lubrication under all operating conditions.
Differential Pressure Oil Supply
The system utilizes differential pressure for oil supply, eliminating the need for external oil pumps. This passive oil management approach improves reliability while reducing maintenance requirements.
Wide Operating Range
Leaving water temperature ranges from 5°C to 15°C, with cooling water entering temperatures from 19°C to 50°C. This flexibility enables adaptation to various system configurations and application requirements.
Comprehensive Protection Features
Over 20 protection functions ensure safe and reliable operation. The 7-inch touch screen interface provides intuitive monitoring and control, while RS485/Modbus-RTU connectivity enables seamless building management system integration.
Low Noise Operation
Part-load noise levels as low as 65dB(A) ensure quiet operation for noise-sensitive environments. This acoustic performance makes the chillers suitable for installations near occupied spaces.
Application Scenarios
Large Commercial Complexes
Shopping malls, sports arenas, and convention centers benefit from the high capacity and excellent part-load efficiency. The modular configurations accommodate varying cooling demands across different zones.
Industrial Facilities
Manufacturing plants, power generation facilities, and industrial process cooling applications utilize the robust design and reliable performance. The high COP values reduce operational costs for energy-intensive operations.
Hospitality and Healthcare
Large hotels, hospitals, and healthcare facilities require reliable 24/7 cooling with excellent efficiency. The proven reliability and comprehensive protection features ensure continuous operation for critical applications.
