FEATURES OF SYSTEM1.
HIGH EFFICIENCY & COMPACT1-1.
HIGH SEASONAL EFFICIENCY

The actual performance is conducted
under various outside temperatures
depending on weather and seasons,
furthermore, especially for multi
system, not all the rooms are operated
all the time. So over 90% the actual
operation time, air conditioners are
operated at partial capacity instead of
rated capacity.
Considering these, we focused on
energy-saving performance based on actual use.
