Product Description

Products Features

Energy-efficient Performance
The DC inverter low temperature enthalpy-adding scroll compressor which adopts the high pressure chamber of excellent performance. It inhales directly and reduce the overheat loss to improve compression efficiency. Adopting the high-efficiency permanent synchronous motor, the stator is intertwined centrally and the efficiency is greatly improved. Sensorless DC inverter fan motor adopts the electromotive force to realize electrodeless speed regulation between 5Hz-90Hz.
 
Quiet Operation
The unit can operate at low noise thanks to upgraded components design.
9 kinds of quiet modes are available based on the actual application occasion.
The lowest noise value is as low as 40dB(A).
 

Intelligent silent mode
According to the user's usage characteristics and actual load matching, the output capacity of the system can be adjusted automatically in the next 24 hours to achieve automatic silent operation.

Quiet mode of IDU
IDU also adopts DC inverter motor to realize the electrodeless adjustment of speed regulation
The noise is as low as 22dB(A).

Advanced technology ensures unit reliability
Oil return control technology
Exclusive oil storage technology of compressor  
Refrigerant storage and distribution technology
Balancing oil control technology
Oil balance among compressor
 

Humanized operation
Auto address allocation and non-polarity communication
Auto debugging and error detection
Five kinds of auto debugging function
Auto allocation of IDU and ODU address
Auto detection of IDU and ODU quantity
Auto detection of internal error of the unit
Start operation debugging automatically
Real-time judgment of pipeline abnormality
The unit has three emergency functions of module, compressor and fan
The unit has two methods of recycling refrigerant
 

Intelligent management
Dual energy saving operation mode;
DC inverter multi VRF system has two energy-saving modes for users to choose freely to meet the requirement on peak power consumption and power-limiting.
Auto energy-saving: System will automatically adjust parameters and balance the capacity and energy consumption according to the operating status.
Forcible energy-saving: Capacity output of ODU is limited. Depending on power consumption and user needs, 90% or 80% capacity ratio can be selected.
Energy consumption analysis and solution
Emergency stop
ODU will introduce the fire alarm linkage signal directly, under emergency situation, it will stop the unit for operation immediately to avoid bigger losses.

 

Super-long piping distance design, the maximum length of total pipe is 1,000m
Compared with traditional screw chiller, the advantage of DC inverter multi VRF system is the easy and convenient piping. Gree DC inverter multi VRF system is more outstanding in the aspect of actual piping, enabling the AC system to be applied to all kinds of architecture, reducing installation cost of the user.
Maximum amount of IDU in one cooling system: 80 sets.
Customized configuration is needed when there are more than 80 indoor units are connected in one refrigerant circuit.

Wide operation range
Operation range of temperature: cooling -15* ~ 55ºC and heating -30 ~ 24ºC .
*Cooling at -15~ -5ºC is conditional. Please inquire our engineers for more information. Generally, the lowest operating temperature for cooling is -5ºC .
 

New modular load allocation control
Choose unit module according to the operation status to realize efficient operation among modular unit, reduce energy consumption loss and improve energy efficiency of operation, which will enhance the reliability of the unit.
ODU high static pressure design with flexible choice
ODU will choose the corresponding static pressure according to architectural type, the maximum can be 110Pa, especially for the occasions which need to place the ODU inside the house.
