2 TECHNICAL AND DIMENSIONAL SPECIF ICATIONS
2.1
Operating principle
The air-water heatpump uses the energy of the airexistingin the environment. The airrequiredfo r
the proper operation of the heat pump can be drawnfrom the out s id e through a window (mi n i mum
temperature -20°C) or from the s urroun din g environment or from other environments through ducts.
The airdrawn from the environment is sucked through a fanandthe heat existing in air is absorbed
during the passage in a heat exchanger (evaporator). In the evaporator the heat taken from the air is
caused to evaporateat low pressure by the refrigerant (the working fluid in the refrigerant circuit,
is as in a household fridge). The vaporized coolant is sucked by a compressor and raised to a
higher level o f pressure (as in a bicycle pump) and temperature. In a second heat exchanger
(condenser) the higher temperature hea t is absorbed and transferred to the water; this way the

Cool Energy EcoStore Heat Pump Water Heater
7 | P a g e
vaporized refrigerant f l u id switches back to the liquid state as a consequence of thermal dissipation.
The liquid refrigerant, f l owi ng through a choking component (expansion valve), undergoes a low
pressure expansion and,after returning to the evaporator, it canagain draw heat fromthe surrounding
environment.
The hot water heat pump operatesat ambient temperatures ranging between -20°C and + 4 3° C.
The hot water heat pump is a connection-ready equipment whose function is heating drinkable
water; it basically consists of the water tank and of the refrigerant, air and water circuit components,
as well as of all the c o ntrol , adj u s t ment and monitoring devicesrequired for automatic operation.
> Use o f th e environment e n e r gy
Refrigerators, washing machines, heating systems and other equipment/electric appliances generate
heat that in most cases is not re use d . Ins t ead of being dispersed into the environment, generating
pollution, the hot air in question can suitably be used to heat sanitary water: a sensible and
environment-friendly solution.
An important benefit is the air dehumidification resulting from heat suction, decreasing the degree of
humidity in cellars and laundries.
This has two beneficial e ffec t s: environment protection and production of cheap hot sanitary water.
2.2
Energy ef ficiency
> Free ener gy
The necessary energy for the heating of sanitary water comes for 2/3 from the air and 1/3 from the
electric power s u pp l y .
> Coo ling through the heat pump f o r hot sanitary water
After heat s u b t r a c t ion, the lower-temperature output air can be used during summer to cool t h e
environment where the heat pump is installed.
This provides a double benefit, while ensuring optimum energy eff i ciency .
> multi use of energy
The heat pump can be beneficially installed in stores, workshops, commercial, residential
applications etc. to gethot sanitary water and, if n ee d ed , cooled a i r .

• Defrosting during water-heating .
In heat pump running per i o d , if the evaporator frosted in lower ambient temperature, the
system will defro s t automatically to keep effective performance(circa 3~10 min . ). At defrosting
tim e , the fan motor will sto p , but compressor will stillrun.
• CO P
The COP (Coefficient o f Performance) varies when the environmental temperature varies.
Norm al ly , lower is the environmental temperature, higher will be the water heating.
•When the environmental temperature is inferior to 2°C, the heat pump and the electric
element work together order to reach the plannedtemperature (see thechart).
