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

 Indicativelyitlastsaboutsixhours.



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.

“CF” is displayed when the limescale ﬁl-

ter needs replacing. The efﬁcacy of the ﬁlter

depends on water hardness.

Setting water hardness
