Fig. 1 – Operating principle
The operating principle of the equipment is as follows
(Fig. 1):
I-II: The coolant fluid sucked in by the compressor flows
inside the evaporator and while it evaporates, it absorbs
the "ecological" heat given by the air.
At the same time, the ambient air is sucked in by the
equipment by a fan; the air loses it heat by passing over
the finned-tube battery of the evaporator;
II-III: The coolant gas passes inside the compressor
and it under goes an increase in pressure that causes a
rise in temperature; transforming this into superheated
steam;
III-IV: Inside the condenser, the coolant gas releases its
heat to the water inside the tank (boiler). This exchange
process makes it possible for the coolant to pass from
superheated steam to a liquid state by condensing at a
constant pressure and undergoing a reduction in
temperature;
IV-I: The liquid coolant passes through the lamination
valve, it undergoes a sudden drop in both pressure and
temperature and it partially vaporises bringing pressure
and temperature back to the initial conditions. The
thermodynamic cycle can begin.
2.5 Available versions and
configurations
The heat pump is available, in relation to the thermal
power (1.9 kW version), which can be set up in different
configurations, depending on the possible integrations
with other heating sources (e.g. solar thermal, biomass
power, etc.).

3 Handling and transport

The equipment is supplied in a cardboard box (*). It is
Hot water
fastened to a pallet with three screws.
Cold water Use a fork-lift truck or a pallet truck in order to unload
the equipment: it is opportune for these to have a load
capacity of at least 250 kg.
In order to make it
easier to loosen the
fixing screws the
packaged equipment
may be put in a
horizontal position on its
back side.
The unpacking
operations must be
carried out carefully so
as not to damage the
equipment enclosure if
this is carried out with
knives or cutters to
open the cardboard
packaging.
After having removed
the packaging, make sure that the unit is intact. If in
doubt, do not use the equipment and seek help from
authorised technical staff.
In conformity with environmental protection regulations,
make sure that all the accessories supplied have been
removed before discarding the packaging.
(*) Note: at Daikin's discretion, the type of packaging
may be subject to change.
For the entire period in which the equipment remains
idle, waiting to be used, it is opportune to protect it from
atmospheric agents.
