Available Versions And Configurations; Handling And Transport - TESY EVHP Series Manual

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 throttle 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.

1.5. Available versions and configurations

The heat pump is available in two different versions, in
relation to the thermal power (EVHP and EVHP S
versions). Each version, in turn, can be set up in different
configurations, depending on the possible integrations
with other heating sources (e.g. solar thermal, biomass
power, etc.).

2 TRANSPORT AND HANDLING
The equipment is supplied in a cardboard box. It is
fastened to a pallet with three screws.
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
authorized technical staff.
In conformity with environmental protection regulations,
make sure that all the accessories supplied have been
removed before discarding the packaging.
WARNING! Packaging items (staples,
cardboard boxed, etc.) must not be left
within the reach of children as they are
dangerous.
(*) Note: at the manufacturer's discretion, the type of
packaging may be subject to change.
