4 - FUNCTION OVERVIEW
4.1.- Intended use and functions
This product is an appliance designed for the production of
domestic hot water (DHW) and conditioning of small and
medium-sized civil and residential environments.
It consists of a reversible circuit inside which a refrigerant fluid
is contained, which evaporates inside the plate heat exchanger
and condenses inside the evapo condensing battery. On the
other side of the plate heat exchanger, by means of the pump
inside the machine, the water (heat carrier) is circulated,
intended for internal users, such as fan coils, underfloor
radiant panels, etc.
It is possible to connect an integrative heat source to improve
the heat output.
The appliance must operate with a difference temperature
of 5 ° C between the supply temperature and the return
temperature, which is only guaranteed with a correct sizing
of the hydraulic system; the designer will have to evaluate
all the pressure drops existing in the system, which must be
lower than the available pressure drops (see Figure 5-20)
for the water flow rate. An incorrect sizing of the system is
one of the cause of the intervention of the low water flow
detector.
The evapocondensing battery has the task of dissipating the
heat taken from the rooms or absorbing heat from the outside,
in the heat pump cycle (HP); for this purpose, the unit must
be properly ventilated respecting the installation distances as
indicated in section 5.3.
There is only water circulating between the unit and the heat
radiators. This ensures greater safety in the unlikely event of
a refrigerant gas leak, which in any case is dispersed outside.
The refrigeration cycle inside the air conditioner is activated
by the compressor.
• This air conditioner is used to cool water up to a temperature
of 7 ° C. In the case of heat pump, it can heat the water up
to a maximum of 55 ° C.
• It must be connected to an heating/cooling system
compatible with the characteristics, performance and power
of the appliance itself.
• Before installation, it is necessary to thoroughly wash
the hydronic system, in order to remove any residues or
impurities that could compromise the proper functioning of
the appliance.
WARNING !!! Refer to section 5.8 regarding the
sizing of the hydraulic system. Failure to comply with this
requirement causes malfunction of the air conditioner.
WARNING !!! Refer to section 5.3 as regards the
minimum distances of respect. Failure to comply with this
requirement causes malfunction of the air conditioner.
