The new sizes of the heat pump range Sheen EVO 2.0 (WiSAN-YSE1) and the new chiller range ELFOEnergy Sheen EVO (WSAT-YSi) are equipped with inverter scroll compressors using R32 refrigerant, and inverter fans with larger diameter compared with the already available sizes.
The WiSAN-YSE1 heat pump range extension has a heating capacity from 98 to 138 kW, and is the ideal solution to meet different kind of applications thanks to full inverter technology and wide operating range.
It’s available in two different energy versions:
The WSAT-YSi with full inverter technology and wide operating range from 110 to 130 kW, will be available in a single high efficiency version reaching a seasonal efficiency in cooling (SEER) up to 5,10.
The use of R32 refrigerant, with a low GWP (Global Warming Potential = 675), guarantees an environmental impact that is about -70% compared to traditional R-410A refrigerant (GWP = 2088).
Inverter scroll compressors, high efficiency DC fans with variable speed control and larger diameter, copper aluminum coils with hydrophilic treatment as standard for the heat pump range or microchannel full aluminum coils for the chiller range, are some of the technologies available that allow to:
The range extension of the heat pump Sheen EVO 2.0 offers 2 different acoustic levels with the related performances, without changing the unit dimensions:
The night mode is also available, for a further reduction of the unit noise emissions by 3dB(A) compared to the super-silent version.
The capacity range for standard and super-silent configurations varies according also to the 2 selectable energy versions:
EXCELLENCE Version:
PREMIUM Version:
The range extension of the chiller ELFOEnergy Sheen EVO offers 4 different acoustic versions:
The capacity range for each noise configuration changes, and so to estimate the reduction of silent, super-silent and night mode, correction factors are available in the technical bulletin.
The capacity modulation from 100% to 30% and the extended operating limits that guarantee the operation all year round, are able to satisfy the requirement of multiple operating conditions.
Due to dedicated design, the range extension of the heat pump Sheen EVO 2.0 EXCELLENCE is able to produce:
The PREMIUM version keeps instead the same, already competitive, envelope of the already available smaller sizes except for the maximum leaving water temperature of 55°C down to 0°C ambient (instead of -4°C as it is for the sizes up 40.2 of the already released range).
The range extension of the chiller ELFOEnergy Sheen EVO grants the same wide envelope of the already available sizes up to 40.2, and so:
Both the ranges Sheen EVO 2.0 and ELFOEnergy Sheen EVO are designed to connect up to 16 units in a local network, reaching a maximum system capacity of 2200 kW in heating and 2080 kW in cooling.
Thanks to the new electrical control box, are available many additional function to better fit each specific installation requirement:
