Gree central Air Conditioner--Digital VRF system

-

Advanced Contral Function

Better Reliability

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)

-

Features:

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.

-

Heater exchanger

The bigger condenser increases heat-exchange area,improving efficiency.

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 performance.

-

Better comfort

Quiet operation

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 50dB(A)

Lower Nosie design

Outdoor uint:

Compressor has lower exhaust pressure fluctuation so that noise is lower.

The optimized design of condensing fan blade reduces the air flow turbulence among blades,so that the noise is lower.

-

Comfortable

Precise temperature control

Intelligent defrost technoloty

Humanized technology which considers the maximization of energy saving

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.

Individual control

The set temperature of each room are may vary by the individual thermostat control of each indoor unit.

Excelletnt dehumidifying performance

-

Higher reliability

Modular operating

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.

Emergency operation

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.

-

Anti-corrosion

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 to 99%

Oil equalizing pipe connection design at the outside of the modules allow high reliability

-

Better versatility

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 indoor unit—40m

-

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 buildings.

-

Wide operation range

The unit can operates in wide range, greatly reducing the ambient temperature limitation.

-

Compact design

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 the industry.

-

Various combinations

Up to 110sets of indoor units can be connected

11 types and 66 models

Maximum diversity is 135%
