7 Digital Multi VRF Technical Sales Guide 5 FEATURES High efficiency and energy efficiency: Today s owners of chilled water plants demand high efficiency and energy efficiency from their chillers. The GREE C centrifugal chillers, equipped with variable frequency drive, maximize chiller efficiency by optimizing compressor operation. Electric power consumption drops dramatically when the motor frequency low. The C chillers deliver industry-leading integrated part-load values (IPLV). The governing mechanism of the chiller use high efficiency ternary impeller and movable diffuser. The new impeller equipped with back sweep long-and-short vane, which ensure the high efficiency at full-load and part-load. The movable diffuser adjusts the area of gas flow passage and maximizes chiller efficiency at part load.new heat-exchanger reduces dramatically heat-exchange resistance when using ultra-high efficiency heat-exchange pipe and increase dramatically the chiller s capacity and the coefficient of performance. Environmental leadership: GREE has long been committed to the environment and its sustainability. The GREE C centrifugal chillers provide our customers with a high-efficiency, chlorine-free long-term solution unaffected by refrigerant phaseouts. The GREE C centrifugal chillers utilize non-ozone depleting HFC-134A refrigerant provides our customers with a safe and environmentally friendly choice without compromising efficiency. Therefore, the effects of potential direct or indirect global warming are greatly diminished. Reliability: The chiller s simple, positive pressure compressor, coupled with new high efficiency heat exchangers, ensures superior reliability and sustainability. The compressor designed by America Concepts NREC-constructed pro-fessional software and checked the oscillation and critical speed by Ansys and DyRoBeS software. GREE s semi-hermetic motors operate in a clean-liquid, refrigerant-cooled environment. The semi-hermetic design eliminates the potential for shaft seal leaks and refrigerant/oil loss. These are just some of the reasons why the chillers have the industry s lowest leak rate. High-strength aluminium alloy-constructed impeller has high strength and preferable corrosion resistance. The impeller is tested to ensure proper operation, including profile test, dynamic balance running and over-speed test and so on. Positive Pressure design: The chiller s positive pressure design reduces dramatically the chiller size compared to lowpressure designs. The smaller size minimizes the need for valuable mechanical room floor space. In addition, positive pressure designs eliminate the need for costly low-pressure containment devices, reducing the initial cost of the system. Optional unit-mounted starter: Available in low-voltage wye-delta and solid state, the chiller s unit-mounted starter provides a single point power connection, reducing chiller installation time and expense. Compressor features: The chillers with the capacity less than 5200kW are designed for single-stage compressor and 7

8 the chillers with the capacity more than 5200kW are designed for two-stage compressor. This design increases product reliability by eliminating the additional moving parts associated with multiple stage chillers, such as additional guide vanes and complex economizers. Capacity regulating device is composed of Inlet Guide Vane (IGV), high efficiency ternary impeller and movable diffuser, and orifice plate and electronic expansion valve, that can achieve capacity step-less regulation at 0~100% load and matches for actual load.the motors are hermetically sealed from the machine room, cooling is accomplished by spraying liquid refrigerant on the motor windings. This highly efficient motor cooling method results in the use of smaller, cooler-running motors than could be realized with air-cooled designs of the same type. Thus, hermetic motors require less inrush current and are smaller and lighter than comparable air-cooled motors. Heat exchangers feature: New heat-exchanger specially design for centrifugal chiller uniform the distribution of refrigerant and rationaliz-ation the temperature field, thus increase heat-exchange efficiency. The new heat-exchanger reduces dramatically heat-exchange resistance when using ultrahigh efficiency heat-exchanger pipe and increase dramatically the chiller s capacity and the coefficient of performance. The condenser baffle prevents direct impingement of high velocity compressor gas onto the condenser tubes. The baffle eliminates the related vibration and wears of the tubes and distributes the refrigerant flow evenly over the length of the vessel for improved efficiency. Advanced control system: The advanced control system provides unparalleled ease of operation and full automatic running of the chiller. The LCD(liquid crystal display) display chiller s operating, status and diagnostic messages for improved user interface. Modular pull-out/plug-in design, reducing wiring requirements and providing easy installation, and low-voltage design, providing the ultimate assurance of personal safety and control integrity. 8
