This series of
water-water
heat pumps satisfies the heating,
cooling and domestic hot water production requirements of au-
tonomous or centralized residential plants of medium and large
size.
All the units are suitable for indoor installation and can be ap-
plied to
fan coil
plants,
radiant
floor plants and high efficiency
radiators
plants.
As source both water (from well, river, lake…) or brine solutions
(from geothermic probes) can be used.
The control system allows to manage not only the refrigerant
circuit but the whole plant with the possibility to choose different
solutions both for the heating and cooling plant and for the do-
mestic hot water management. The possibility of solar panels or
other heating sources integration is also available.
The
heating
function optimizes the flow water temperature ac-
cording both to the ambient temperature and to the outdoor tem-
perature through climatic curves adaptable to the building featu-
res. It’s possible to manage a storage tank and two independent
circuits (a direct one and a mixed one).
The
domestic hot water
management allows to control the th-
ree way valve, the storage tank and the anti-legionella cycles (if
necessary).
The
cooling
function can be realized through “passive cooling”
(free cooling), through “active cooling” (refrigerant circuit inver-
sion) or through both systems actuated in sequence. When the
unit is used in radiant floor plants, to avoid condensate gene-
ration, a room humidity sensor can be installed. During cooling
mode operation a part of the heating power in excess can be
recovered for the domestic hot water production (VD version).
The
internal programmer clock
allows to define different daily
switching programs for heating, cooling and domestic hot water
production.
The refrigerant circuit is equipped with scroll compressor
mounted on damper supports, brazed plate heat exchangers,
electronic expansion valve and reverse cycle valve (for rever-
sible units). The circuit is protected by high and low pressure
switches and flow switches on both the exchangers.
In the low noise setting up units (AS) the outdoor structure is
thermally and acoustically insulated
in order to reduce sound
propagation and to allow the installation in domestic places.
All the hydraulic pipes are thermally insulated to avoid conden-
sate generation.
All the units are supplied with phase sequence and voltage con-
troller and with an outdoor temperature sensor in order to realize
the climatic control.
All the units are accurately built and individually tested in the
factory. Only electric and hydraulic connections are required for
installation.
