3 Product Features
3.1 General introduction
Gree DC Inverter Multi VRF System II is the latest generation of DC inverter units. One set of
air-cooled outdoor unit can be connected with multiple direct evaporation indoor units that are of the
same or different forms and capacity. This refrigerating system can directly provide air conditioning for
one or more areas, and is applicable for residential and light commercial uses. It features high energy
efficiency, strong anti-interference capability, long connectable pipe, wide operation range, good sound
quality, intelligent capacity regulation, complete protection, etc.
3.2 Features
(1) Super high energy efficiency
The 2nd generation of DC Inverter Multi VRF System adopts DC motor to realize complete direct
current and upgrade the energy efficiency. EER is up to 3.97 and COP can reach 4.28.
(2) New generation CAN bus communication
Due to the latest communication method—CAN Bus Communication, system’s anti-interference
capability is stronger and the control on indoor units is more accurate, with higher reliability.
Specialized shield wire is no more needed and ordinary communication wire can be applied in
the construction, which has increased the installation flexibility.
(3) Long connection pipe
The maximum length of connection pipe is 300m (in total) and the farthest connection pipe
between indoor and outdoor units can be 120m’s long, which has extended the installation
condition and reduced the limit of installation distance.
(4) Wide operation range
Units can operate reliably in a wide temperature range (cooling: -5~52
ć
, heating: -20~27
ć
).
(5) Fine sound quality
