GENERAL FEATURES
Unit description
This series of
air-water heat pumps satisfies the heating, coo-
ling and domestic hot water production requirements of residen-
tial plants of small and medium size.
All the units are suitable for outdoor installation and can be ap-
plied to
fan coil plants, radiant floor plants and high efficiency
radiators plants.
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 “active cooling”
(refrigerant circuit inversion). When the unit is used in radiant
floor plants, to avoid condensate generation, a room humidity
sensor can be installed.
The
internal programmer clock allows to define different daily
switching programs for heating, cooling and domestic hot water
production.
The refrigerant circuit, contained in a box repaired from the air
flow to simplify the maintenance operations, is equipped with
rotary or scroll compressor (according to the model) mounted
on damper supports, brazed plate heat exchangers, thermosta-
tic expansion valve, reverse cycle valve, axial fans with safety
protection grilles, finned coil realized with copper pipes and al-
luminium fins. The circuit is protected by high and low pressure
switches and differential pressure switch on the plate heat ex-
changer.
The plate heat exchanger and all the hydraulic pipes are ther-
mally insulated in order to avoid condensate generation and re-
duce thermal losses.
All three-phase power supply units are provided with a phase
sequence and correct sequence controller device.
All the units are supplied 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.
