High performance central air conditioning system with multi- functions

Gree central air conditioning system with heat recovery function.

GMV HR II 2008-2009

2nd Generation of Gree Heat Recovery VRF System with DC Inverter Technology, highly improved heat recovery efficiency and system reliablity, with a largest combination of 64HP.(180KW)

GMV HR 2006-2007

1st Generation of Gree Heat Recovery VRF System with Digital Scroll Compressor and R410A with capacity of 10HP.(28KW)

Significantly greater energy efficiency

Significantly greater efficiency is realized by the use of DC Inverter Hermetic Scroll compressors with high pressure chamber design, and improved DC inverter driving technology, and large heat exchanger.

* Cooling Energy efficiency rate of partial load reaches up to 4.6.

*ECOP under heat-recovery mode reaches up to 6.8, which is 78% higher than a traditional VRF system.

Note:

*EER is the energy efficiency rate=cooling capacity(KW) + cooling power input(KW)

COP is the coefficient of performance= Heating capacity(KW)+ Heating power input(KW)

*ECOP is the Economic Coefficient of performance

(When the system is operate as heat-recovery mode)= cooling capacity(KW)+Heating capacity(KW)+ Power input(KW)

*EER/COP/ECOP values are based on Gree laboratory testing method.

*The data refers to a 10HP(28KW)System.

MEU(Mode Exchange Unit)connects before each indoor unit, performs the function of real-time operation mode exchanging (Cooling to heating, Heating to cooling)

Operating principle of MELL in cooling & heating mode.
