VRV vs DX Inverter Life Cycle Cost Analysis

[PS]

Hello everyone,

I'm doing a comparison between DX inverter model machines and VRV/VRF sytem. I'm comparing in all terms, CapEx, OpEx, system performance, ease of operation, etc.

I'm in need of data like ikW/TR for DX inverter and VRF systems. Further to that, is it a good idea to compare the VRF system and DX inverter sytem with their corresponding IEER values?

I'm a bit confused whether to take EER value or IEER value to calculate the power consumption. Would anyone please throw some light in helping doing it?

Thanks in advance!
