Start operation debugging automatically
Real-time judgment of pieline 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;
With the deepening of energy conservation and emission reduction and the stricter national
requirements to urban electricity consumption, especially in summer, the peak season of electricity
consumption, many cities will introduce corresponding power-limiting measures. Gree 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.
Energy saving mode 1: When the unit is set in auto energy saving operaiton, the system will adjust
the control target parameter automatically, which greatly reduces the power consumption quanity of the
unit, energy saving rate is as high as 15%.
Energy saving mode 2: When the unit is set in compulsory energy saving operation, the system will
realize 20% of energy conservation at the most through limiting electric quantity output compulsorily.
Energy consumption analysis and solution
Emergency stop
Long distance monitoring is needless, ODU will introduce the fire alarm linkage signal directly, under
emergency situation, it will stop the unit for operation immediately to avoid bigger losses.
Partition management
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.
Cooling only system, the maximum attachable quantity of IDU is 100 sets
The attachable quantity of single system of most of the multi VRF systems in current market is 64 sets,
whiel Gree DC inverter multi VRF system is integrated with several modular unit and can connect 100
sets of IDUs at the most, which is more applicable for large commercial office buildings, apartment or
hotels.
* The 100 sets of unit can be custom made.
Wide operation range
Operation range of temperature: cooling -5 ～ 55℃ and heating -30 ～ 24℃ .
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 form, the maximum can
be 110Pa, especially for the occasions which need to place the ODU inside the house.
