EFFICIENCY IN ACTUAL OPERATION

The building load is the range of almost 40 % to 80%. Therefore, most air conditioners do not
operate at maximum load, but operate at low to medium loads. Especially, for multi system,
operation performance at partial load is important because all the air conditioners do not
always operate all the time. Aiming at energy saving performance matched to actual operation,
Fujitsu General has developed a high intermediate performance air conditioner corresponding
not only to the rated performance at 100% load, but also to low to medium load
