Mitsubishi Electric Hydronics & IT Cooling Systems extends its range of Climaveneta multi-purpose heat pumps and introduces i-NX-Q: air source multi-purpose unit with scroll inverter compressors and a cooling capacity from 43 to 151 kW. The variable speed technology shows its advantages especially when applied to multi-purpose units. The new i-NX-Q units achieve consistently higher efficiencies than similar fixed-speed units, with any combination of cold / heat load, and in any season.

In a traditional comfort application, the HVAC system works at maximum power only for a limited number of hours per year, while most of the time it operates in partial conditions. It is in this situation that the efficiency achieved by the units with inverter technology is different from that of traditional fixed speed units: SCOP + 20% and SEER + 29%.
The presence of variable speed compressors provides optimal efficiencies in simultaneous load conditions measured with the TER - efficiency ratio, developed by Mitsubishi Electric Hydronics & IT Cooling Systems, which is always abundantly higher (¬ up to + 19%) than those of a unit with speed-fixed compressors.
