Gree central air conditioning system C series contrifugal water-cooled chiller

C series contrifugal water-cooled chillers is a new generation high energy efficiency water chiller,by Gree company independent research and development.adopt international leading manufacturing and processing technology and Microcomputer control system, refrigeration capacity 1000-7800kw,  be widely used in large office building, hospital,school,supermarket,factory etc.

Features:

1.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

2.Variable frequency control, high efficiency and energy saving

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%

3.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

4.Semienclosed 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

5.Wide operating range

Patented diffuser technology and micro-pressure oil return technology greatly extends the operating range of the unit, the unit stable running in range of the cooling water inlet temperature 15-35℃ , 10-100% load stepless adjustment, exactmatch the actual load 

6.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

7.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

8.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

Special Note about Voltage:

We have different models to meet customer requirement in different regions,so don't worry about it.
