Improved Compressor

The new HITACHI DC Inverter Scroll compressor is

designed to have higher

performance at low load operation :

+ 4.6 % in seasonal efficiency ,

also an increased efficiency and reliability and reduced power consumption .

Smart Refrigerant Temperature control is adaptative,

so for if load is low or the set temperature is close to the actual one ,

will prevail evaporating temperature increase .

In contraposition ,

if load demand is high or difference from set point and real temperature is high ,

evaporating temperature is decreased and compressor frequency is increased .
