SHERPA AQUADUE
Multi-purpose split heat pumps, suspended and tower versions
The AQUADUE® patented technology thanks to the combination of an air-water cycle with inverter technology and a second stage water-water guarantees the cooling or the heating contemporary to the DHW production at high temperature, indipendently from the outside temperature.
FEATURES
Inverter air-water heat pump
• Energy efficiency class in average climate heating up to: A+++ (35°C) and A++
(55°C)
• Powers available: 4 Powers with refrigerant R32 (4-6-8-10 kW single-phase) and
3 Powers with refrigerant R410A (12-14-16 kW single-phase and three-phase).
• Production of DHW (Domestic Hot Water) at high temperature, up to 75°C.
• DHW management: a water/water heat pump unit integrated in the internal
unit supplies domestic hot water at high temperature regardless of the external
climatic conditions.
• Absolute continuity availability of DHW: guaranteed by the redundancy of the
dual cooling cycle system
• Anti-legionella cycles that can be avoided using the high temperature
refrigeration cycle.
• Double stage electric heating elements as standard: activation of single
or double heating element to support the heat pump by means of a simple
electronic control configuration. Each stage is activated according to the actual
need for thermal power, in order to optimise electricity consumption
(supplied disabled by default).
• Configurable set points: two set points in cooling, Three set points in
heating (one of which for DHW): the set points can also be selected via
remote contact.
• Holiday and weekly programmer: heating/cooling, DHW, night-time.
• Climatic curves with external air temperature probe: two curves available,
one for cooling and one for heating. The climatic curves are used to vary the
temperature of the water supplying the system according to the external
climatic conditions, adjusting the thermal needs of the building, in order to
achieve energy savings.
• Refrigerant gases: R32* or R410A* for the reversible circuit dedicated to air
conditioning and R134a** for the high temperature circuit dedicated to the
production of DHW.
• Built-in 150 L high efficiency storage tank (tower version) with an
exchange battery surface equal to 1.5 m2.
DHW AND COMFORT AT THE SAME TIME
The two interconnected refrigerator cycles allow the
decoupling of the heating/cooling from the DHW
production, enabling them to operate in parallel,
avoiding thus interruptions in the domestic comfort
supply.
DOMESTIC HOT WATER UP TO 75°C
The storage of DHW at high temperature makes
it possible to reduce the volume of the storage
tank by up to 30%, and to avoid energy-intensive
consumption of the anti-Legionnaire’s disease
cycles, since they are normally carried out by the use
of electric heating elements.
LOW GWP GAS
In sizes up to 10 kW, it uses the R32 refrigerant,
characterised by greater efficiency and a greenhouse
effect reduced by almost 70% (compared to R410A).
