WHAT IS THE WATER-AIR PINGUINO
During the summer, you feel comfortable at a
temperatureofbetween24and27°Cwitharela-
tivehumidityofabout50%.
Anairconditionerremovesexcessmoistureand
heatfromtheroomwhereitislocated.
Compared with wall mounted models, portable
airconditionershavetheadvantagethattheycan
bemovedfromoneroomtoanotherinthehome
orbetransportedfromonebuildingtoanother.
Hotairfromtheroomispassedthroughacoil
cooledbyrefrigerantgas.Excessheatandmoi-
sture are removed before the air is re-emitted
intotheroom.
Insingleunitmodels,asmallpartofthisairis
usedtocooltherefrigerantgasandthen,when
hotanddamp,isdischargedoutside.
In exclusive De’Longhi water-air models, the
heatisremovedfromtheroomthroughthecoo-
lingeffectofthewaterwhichisobviouslymuch
greaterthanair.
Thisgivesthisairconditionerunbeatablecooling
efciency.
WHAT IS THE PINGUINO INVERTER
TheInvertertechnologyhasbeendesignedtoof-
ferthebestcomfortwithoptimisedenergycon-
sumption.Itguaranteesveryhighcoolingpower
to rapidly reach the set temperature, which is
thenmaintainedconstantovertime.
Thistechnologyisessentiallybasedonanelec-
tronicdevicethatallowsfrequencyvariationsof
theelectricmotor,toadjusttherotationspeedof
thecompressorandobtainamodulationofthe
coolingpower.
ThisdeviceeliminatesthesequenceofOn–Off
requiredbyconventionalairconditionerstokeep
a xed room temperature, with consequential
high temperature uctuations around the set
temperature and longer time gaps before it is
reached.
The Pinguino Inverter always operates at the
optimum cooling capacity and the maximum
energy efciency as the powerconsumption is
limitedtoeffectiverequirements,bothinperiods
of average and low thermal load (morning or
evening), and during the hotter and more hu-
midtimes(middleoftheday),whentheInverter

The appliance is fitted with a resin lime-
scale filter enabling normal tap water to be
used.
The impregnated resins reduce water hardness
and therefore prolong the working life of the
appliance.

ter needs replacing. The efficacy of the filter
depends on water hardness.
