GENERAL INDEX
2-Pipe ECOi EX ME2 Series
Extraordinary partial load, SEER and SCOP.
Efficiency in VRF systems
In the past it was only possible to compare the nominal efficiency at outdoor ambient temperature of 35 °C (EER) in
Cooling and at 7 °C in heating (COP). With EN-14825 seasonal efficiency will be shown, the result will be SEER and SCOP.
ECOi EX is reaching excellent performance without using any additional saving functions.
The highest EER / COP rating in most capacities
Compared to conventional model ECOi (ME1)
The ECOi EX marks a revolutionary step forward in VRF efficiency. A look at the incredible EER / COP value clearly
indicates that. What’s more, this high EER / COP value is achieved even during part load operation. This shows the
extraordinary energy-saving performance the ECOi EX is capable of providing.

2-Pipe ECOi ME1
Partial load for seasonal and real system efficiency
VRF units are designed to adapt to the heating and cooling demand, adapting its performance to different outdoor
conditions. When compressor runs at lower than 100% capacity, the system is working at partial load. A wider compressor
operating range results in better system performance both at full load and partial load conditions. Panasonic ECOi EX
partial load is excellent, reaching a minimum of 15% of compressor capacity.
Excellent efficiency at any condition and partial load
In both heating and cooling mode, Panasonic ECOi EX is reaching exceptional levels of efficiency.
