De'Longhi is the world leader in portable air conditioners and the exclusive holder of the patented "water-to-air" technology.
The Pinguino air conditioners that use this technology are different to the "normal" (air-to-air) conditioners because they use water to dissipate heat when hot air enters the condenser. De’Longhi’s exclusive and state-of-the-art water cooling system effectively cools the technological core of the unit with a cloud of micro water droplets which evaporate immediately and are discharged. It is through the superior cooling capacity of water that an unprecedented level of air conditioning efficiency is achieved. This uniqueness makes the Pinguino water-to-air conditioners superior to all the other portable monoblock conditioners currently on the market, and therefore cannot be classified according to the European laws governing energy labelling, EN14511.

The pinguino WATER-TO-AIR is energy efficient
Water-to-gas-to-exchange circuits-to-water-to-atmosphere. The virtuous cycle of cooling is unique to the De’Longhi Pinguino.
High levels of efficiency and effectiveness are achieved through the use of water, delivering optimised performance with lower energy consumption. The efficiency, measured by the EER (Energy Efficiency Ratio), or the relationship between the cooling power delivered and consumption, is an absolute number whose value determines the energy efficiency class. For example, in order to reach class A, the EER needs to be equal to or greater than 2.60.
The figures below illustrate this:
||EER > 2,60
||The EER of the water-to-air conditioners can be as high as 3.58 (Pinguino De’Longhi PAC WE110ECO model).
The EER of an air-to-air class A is 2.60. This means that the De’Longhi water-to-air models should be in a higher energy class than class A, but currently the energy classification dictated by the European law EN145111 excludes these “unique” air conditioners.
||2,60 = EER > 2,40
||2,40 = EER > 2,20
||2,20 = EER > 2,00
||2,00 = EER > 1,80
||1,80 = EER > 1,60
||1,60 = EER
Pinguino Inverter Water-to-Air is the combination of the power of water-to-air technology and the efficiency of the DC Inverter compressor.
DC Inverter technology has been designed to offer the best comfort with optimised energy consumption. It guarantees very high cooling power to rapidly reach the set temperature, which is then maintained constant over time with thermal swings as low as +/- 0.5 °C.
This technology is based on an electronic 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 fixed room temperature, with consequential high temperature fluctuations around the set temperature and longer time gaps before it is reached.
Perfect temperature, sheer comfort
The Pinguino Inverter always operates at the optimum cooling capacity and the maximum energy efficiency as the energy consumption is automatically restricted to what is actually needed, by adapting to varying external temperatures, both in periods of average and low thermal load (morning or evening), and during the hotter and more humid times (middle of the day), when the Inverter technology is especially valuable.
Thanks to the extremely high cooling power, Pinguino Inverter quickly reaches the desired temperature and keeps it constant over time. Perfect temperature, sheer comfort
