I try to compare COP between VRF inverter and VRF digital scroll. Basically I check from catalogue. COP of Daikin VRVIII are quite higher than Digital scroll but I receive some actual test data from Emerson Copeland to show that COP of digital scroll is better.
There is one comment that the power consumption in catalogue is not included the inverter loss because they test VRF inverter by suppling power to compressor with fix frequency (no inverter loss as per the actual usage). I check details in Daikin VRV III technical manual, it has remark - Power Input : kW(Comp.+Outdoor fan motor). Do anyone can confirm the fact for this? If COP in catalouge are actually not included inverter loss, then how much the additional power consumption for inverter loss by approximately.
