Gree industrial air conditioner system CT series high efficiency centrifugal water chiller

Own independent intellectual property rights of a centrifugal compressor special designed for high-temperature chilled water (12℃-20℃). unit 16℃ water reach up to COP of 8.6, in the same conditions  saving more than 30% than ordinary centrifuges .identified by The authority of the expert group in air conditioning industry the leading international level.

CT series high efficiency centrifugal chillers have a wide range of applications in large office buildings, industrial plants and processes, especially for below region:

Features:

1.   Gree patent efficient compressor, saving energy 30%

12℃-20℃ in the freezing water conditions, the evaporation pressure is high, the compressor compression ratio is low. Ordinary compressor serious deviation from the design point, down the compressor efficiency, reliability can not be guaranteed. Gree specifically designed centrifugal compressor in full compliance with this working conditions. Higher operating efficiency of the compressor. The same conditions saving 30% more than ordinary centrifuges Greatly reducing unit operating costs.

2.   Compressor design uses a variable geometry diffuser + blade diversion of organic combination of methods to effectively ensure that the compressor is running at part load efficient and stable, no surge

3.  Frequency control, energy efficient

For optional variable frequency drive unit, its cooling capacity adjustment by a motor speed regulation and diversion vane adjustment two perfect combination ways, greatly improving the efficiency of the unit. Relative to rated units, annual energy saving

up to 15-25%

4.   Micro-pressure oil return technology

Without being limited by the high and low pressure difference, under any load, reliable oil return.

5.  Green, positive pressure design

The entire unit designed specifically for R134a refrigerant, R134a as refrigerant CFC-free and efficient (ODP = 0) does not have any damaging effects on the ozone layer, is new and efficient refrigerant. The system uses R134a is positive pressure running, there is no non-condensable gas into the system. System cleanliness is high, no additional purchase necessary vacuum suction recovery unit. Compared with the negative pressure design unit, the unit is compact, small size, can greatly reduce the unit area

6.  High fouling factor design

For different water quality, fouling system of Gree centrifugal chillers, condenser and evaporator according to 0.086m²℃/kW to design, higher than the condenser international requirements 0.044m²℃/kw and evaporator international requirements 0.018m²℃/kW, long-running no cold attenuation, reduce operating costs, meanwhile extend the maintenance cycle 

7.  Closed motor, stable and reliable

Efficiency enclosed type motors that Using spray liquid refrigerant to cooling, not only sufficiently reduce the risk of a large number of refrigerant and oil leakage, but no much heat dissipation, saving room investment and operating costs of adding cooling devices. Gree patented cooling method can precisely controlled operation temperature, ensure running highly efficient and stable

8.  Ultra-efficient heat transfer tube and new heat exchanger

Special Designed for centrifuge of the new heat exchanger allows refrigerant more uniform distribution ,temperature field more reasonable. improve the heat transfer efficiency, ultra-efficient heat transfer tubes of the heat exchanger be able to further reduce the thermal resistance, greatly enhanced unit cooling capacity and EER

9.  Advanced CNC machining equipment

We have many German DMG five-axis machining centers and Toshiba large horizontal Tang milling center, ensure optimum precision of compressor parts.

10. The authority of the testing center

The company has the industry's most advanced large group centrifuge assembly line and on-line test plaform, test capacity of 8800kw, each unit before leaving the factory went through a rigorous full performance tests to ensure the reliability of the unit

11.Color LCD touch screen display control center

Adopt color LCD touch screen as the user interface between man and units, using a variety of display text, images, tables ,curve and so on , the unit can achieve be comprehensive monitored and easy controlled. Multi-angle to record and display the operational status of the unit, sensor status, the status of valves and operating parameters. Event-recording mode record important action and unit fault

12.Advanced control platform

Control systems use a dedicated high-performance 32-bit CPU and DSP digital signal processor, have very high data acquisition accuracy and superior data processing capabilities, ensure the real-time and accuracy of system control. Color LCD touch screen, ensure good man-machine exchange, easy to realize automatic control and manual control when debugging. The advanced Fuzzy - PID compound control algorithm. The control method combined smart technology, fuzzy technology and conventional PID control algorithm, ensuring that the system has faster response time, better steady-state performance
