GENERAL INFORMATION
A LOOK TO THE FUTURE
Technology and architecture
Technological systems represent an important component of the buildings, often seen as an element of disruption, a necessary
"evil".
A modern design brings together living environments and technology in an aestethic and architectural balance that ensures
comfort, power saving and economy throughout the building’s service life.
INNOVA products reect this philosophy, combining the best technological options and modern, clean aesthetics in a single
element, becoming objects of design.
Environment
An essential step for the future of our planet is to reduce the use of fossil energy sources, switching to renewable ones.
Directive 2009/28/EC of the European Parliament and of the Council of 23 April 2009 on the promotion of the use of energy from
renewable sources denes the “environmental heat” in the Air, Water and Earth as renewable source of energy. eHPoca and
3in1 of INNOVA use the environmental heat and the Heat Pump principle to generate and distribute heat-transfer uids that
render the living environments comfortable throughout the whole year.

THE HEAT PUMP
A simple principle...
Its functioning principle is similar to a refrigerator’s one: the heat taken from a low temperature ambient is transferred to a
second one with higher temperature. Similarly, the heat pump takes heat from a cold, outdoor ambient (in winter time) and
transfers it to a warmer, indoor ambient, further heating it up. Moreover, by activating the heat pumps in reversed cycle, you
can cool indoor spaces in summer time: with the same functioning principle, the heat is now absorbed from indoor and delive-
red outdoors.
...a great achievement
More than 75% of the energy used by the heat pump is free because it comes from the Sun and it is stored in air, water and
earth; with only 25% use of electricity, the heat pumps ensure optimum comfort during summer and winter. With the heat
pump you will have one single system for heating, cooling and sanitary hot water production.
Benets
Increase the value of your property
According to Directive (2002/91/EC) of the European Parliament and of the Council, all building should have an energy perfor-
mance certicate considering the primary energy. Used on the same building, eHPoca and 3in1 reduce the primary energy con-
sumption levels by at least 50% compared to the traditional boiler solutions, reaching higher performance classes, increasing
therefore the property’s value, with an average return of investment of 3-4 years.
CO2 emissions reduction
The heat pumps do not use fossil energy sources such as Natural Gas or Oil and do not generate CO2. Even considering the
equivalent CO2generated to produce the electricity, the indirect CO2emissions decrease, on average, by 50% compared with the
combustion systems and by 80% compared with the electrical heating systems.
Costs reduced up to 80%
The average seasonal COP of modern heat pumps can reach up to 4 for the most ecient air-water units. The average per-
formance of the Italian electrical system is 0.46; the performance of a heat pump, referred to the primary energy is 180%,
exceeding therefore the performance of any traditional combustion or electrical generator, resulting in a saving of 50% - 80%
on operating costs.

INNOVA WEB SITE
INNOVA designed an easy to read and use site, on which you can nd information, updated technical documentation, catalo-
gues for the ranges of heating and cooling systems.
The site also features a specic software that you can use to calculate the performance of the product under any operating
conditions.
www.innovaenergie.com
Heat pump web server
The heat pumps INNOVA are supplied with an advanced web access tool thanks to which they can be controlled from your
computer, tablet, smart phone or any device with Internet connection by simply using the browser.
This way, by entering the machine’s IP address, the user will be able to check its status, view any ongoing alarms and even to
change the setpoints. By conguring the web server with the data of your connection, you will be able to receive e-mails whe-
never an alarm occurs.
You will also be able to see, check and control many other devices INNOVA connected to the same ethernet network, such as
AIRLEAF and FILOMURO fancoils.
All this at a very low cost, in a context known throughout the whole IT world, ethernet networks wiring.

THE HEAT PUMP
THE HEAT PUMP HANDBOOK
Below you can nd some key points for the correct operation of the heat pump and for taking advantage of its power saving
potential.
1. The heat pump with vapour compression cycle is a thermodynamic machine, the performance of which increases as the
dierence in temperature between the outdoor ambient and the ambient/water to be heated increases.
2. Point 1 means that, in order to save energy with the heat pump, you need to exchange the heat optimally with the outdo-
or ambient, respecting the recommended ventilation clearances and preparing the internal system so that the pump can
operate at medium-low temperatures (below 45 °C).
3. To nd out which heat pump suits you best, request a thermal calculation for the building, taking into account the type
of internal system and the installation location (for geothermal heat pumps, the installation location is irrelevant within
certain limits).
4. In case of air-water heat pumps, you need to observe the piping installation instructions between external and internal
units to enable correct, ecient and economic operation of the pump.
5. Always make sure that there is enough water in the heating system, installing if necessary, a buer tank; for any infor-
mation, contact your trustworthy designer or our technical department INNOVA.
6. Never heat sanitary water by means of traditional tanks, suitable only for high temperature supply sources (traditional
boilers), but rather by means of boilers with wide instantaneous submerged exchanger (refer to the relevant documen-
tation INNOVA or contact our technical department to choose the right product).
7. After observing the previous point, make sure that the storage temperature does not exceed 47 °C, except in special
cases.
8. Choose the power purchase agreement that suits you best; request the special rates using the INNOVA declaration, and
you will benet from a xed price contract, without tari increase due to consumption bands.
9. For correct assessment of the necessary electric power and of the size of the power line, refer to the electrical data pro-
vided in this manuals; if in doubt, contact our technical department. This way you can avoid common errors that lead to
unnecessary waste of money.
10. If you respect the indications above, the heat pump will become the most ecient system for winter heating, cummer
cooling and sanitary hot water production in residential buildings and not only...

OPERATION
The functioning principle of the heat pump is similar to that of a regular refrigerator that takes the heat from the refrigerator
compartment and releases it into the ambient; you can perceive the heat by touching the heating element outside the fridge,
which represents the condenser.
Similarly, the heat pump takes heat from a low temperature ambient (source: air, water or earth) and transfers it, warming it,
to a warmer ambient (user: houses). Moreover, by activating the heat pumps in reversed cycle, you can cool indoor spaces in
summer time: the heat is now absorbed from indoor and delivered outdoors.

In order to "catch" the heat from the source, the heat pump uses a cooling circuit and a special uid (called refrigerant uid) that,
based on the operating temperature and pressure, can be in gaseous or liquid state.
The cooling circuit consists of:
1. compressor.
2. the condenser (called utilities exchanger when the pump is used for heating and source exchanger when used for coo-
ling).
3. expansion valve.
4. evaporator (called source exchanger when the pump is used for heating and utilities exchanger when used for cooling).
During pump operation, the refrigerant uid undergoes the following thermodynamic transformations inside the circuit:

1-2 Evaporation
the refrigerant enters in liquid state in the source exchanger (point 1), where it evaporates at low temperature (therefore at low
pressure) by subtracting the Q1 heat from the cold source, then exiting the exchanger as saturated vapour.
