2.1 Features and benefits

2.1.1 Improvements of UTOPIA Prime / UTOPIA IVX Prime Series

UTOPIA Prime and UTOPIA IVX Prime series provides the following improvements to air conditioning installations:
1 Changing the compressor from scroll to advanced rotary.
2 Increased working range, in heating mode up to 24/18 °C (DB/WB).
3 Increased working range, in cooling mode for the OU simultaneous operation mode up to -15 °C.
4 External static pressure increases up to 30Pa.
5 Use of R32 refrigerant.
6 Individual control with R32 refrigerant.
7 Improvements in pipeline limitations. Fewer piping restrictions than in previous series.
8 Better efficiency than the previous series.

2.1.2 R32 refrigerant

R32 refrigerant has many benefits over R410A refrigerant.
Although both are "fluorinated greenhouse gases covered by the Kyoto protocol", R32 has a much lower global warming
potential (GWP=675) vs R410A (GWP=2088). This means that it has a lower TnCO2 equivalence, as a much lower
charge is required to obtain better performance due to its better thermodynamic characteristics.
An other advantage of the R32 over the R410A is its greater ease of recovery and reuse, taking into account that its
installation and maintenance are very similar.
In short, the R32 reduces its environmental impact, being much more respectful of the ozone layer and with a low GWP.
In addition, the use of R32 over R410A allows a refrigerant charge reduction of 7-12% for the same installation.
