1.Gree central Air Conditioner
3.Higher Capacity up to 201.6kw(72HP)
4.Digital Scroll Compressor
Gree central Air Conditioner--Digital VRF system
Advanced Contral Function
Compact outdoor Unit Design
Digital Scroll Compressor
Eco-friendly R410a Refrigenrant
Flexible Piping Design
Greatly Improved Energy Efficiency
Higher Capacity up to 201.6kw(72HP)
High efficiency compressor
Advanced PWM variable capacity compressor
Stepless capacity adjustment within 10%-100% can be realized
The PWM(pulse width modulation) digital electromagnetic valve
realizes the purpose of unloading/loading by controlling the
clutching of orbit scroll and the fixed scroll of the compressor,
so as to perform the capacity adjustment.
Prompt response to the load change
Only 120 seconds to achieve the capacity asjustment from 10%-100%.
DC fan motor
Compared with the former model,air flow volume increases by 3% with
the same single fan and 7% with the new dual fan, but the power
consumption decreases by 5%with the DC inverter motor.
The bigger condenser increases heat-exchange area,improving
Compared with the mormal fin,the heat exchange efficiency of the
louver fine is increased by 5%
Special thickened inner groove copper tube enhances heat exchanging
Quiet operation during night time
Intelligently adjustment of outdoor fan control can minimize the
operation noise during night time.
Up to 8dB(A) can be reduced and operating noise at night low to
Lower Nosie design
Compressor has lower exhaust pressure fluctuation so that noise is
The optimized design of condensing fan blade reduces the air flow
turbulence among blades,so that the noise is lower.
Precise temperature control
Intelligent defrost technoloty
Humanized technology which considers the maximization of energy
Defrosting program is designed under the consideration of heating
efficiency and operation reliability.
Precise defrosting timing, wihci is intelligent indeed.
Heating capacity loss has been decreased by 75% with higly
comfortable heating operation.
The set temperature of each room are may vary by the individual
thermostat control of each indoor unit.
Excelletnt dehumidifying performance
The operating priority sequency of the outdoor unit modules will be
changed without restart when the system accumulatively operates for
12hours,which can maximize the service life of the system.
Each module is an independent sub-system, and the whole system
won’t fail down even if partial malfunction.Upon malfunction of any
one of the moudles,emergency operation can be performed after
simply manual set up on the outdoor PCB switches.
Continuous operation of indoor unit
Each indoor unit is controlled individually on the system
network,This allows all indoor units will continue to work even if
an error might occur at any indoor units’s on the VRF system.
Wide voltage range operation
The unit can safely operate within 342V-456V
Power supply security
With power supply security,the outdoor unit will start
auto-protection if the power voltage or the current is out of the
mormal range.Protection will be relived automatically if the power
condition resumes normal.
No electromagnetic disturbance
Stability and reliability
Even under 10% loading, the GMV digital system can still maintian
long time continuous and stable oepration,ensuring the indoor unit
performance in any case of loads.
The primary material of Golden fin is AL-Mn(Aluminum-manganese)
anti-rust alloy,which is coated with the Golden Protection
layer(Components:Epoxy Resin&Modified Acrylic,Silicon free),
the anti-corrosive performance in salt-spray testing is 200%-300%
higher than normal Blue Fin.
New generation of oil return control
Through pressure control,the oil return of the sytem is efficiently
optimized,thus greatly improving operation life of the compressor.
High efficiency oil-balanced technology
New patented oil separator allow the oil separating efficiency up
Oil equalizing pipe connection design at the outside of the modules
allow high reliability
Long piping design
Maximum total piping lengh—500m
Maximum actual piping length—150m
Maximum equivalent piping length—175m
Maximum height difference between indoor units—15m
Maximum height difference between outdoor and indoor units—50m
Maximum piping length from first indoor branch to the farthest
Higher static pressure of outdoor unit
The maximum external static pressure of the outdoor fan can reach
up to 75Pa
The outdoor unit ca nbe installed in the equipments room of high
Wide operation range
The unit can operates in wide range, greatly reducing the ambient
Compact size has been achieved by significantly reducing the width
of the outdoor units compared to previous models.
Modular outdoor unit design
Varous combination from 8HP to 64HP with 2HP increments
Max combination of 4modules,reaching a biggest capacity of 72HP in
Up to 110sets of indoor units can be connected
11 types and 66 models
Maximum diversity is 135%
