Outline of New Series Products

In addition to the use of a new refrigerant (R-407C), the new series products incorporate a function-unit-less structure
for significantly improved flexibility and ease of installation.

R-407C
< Global warming potential >
Water vapor and carbon gas allow solar rays to pass through, but they hinder the penetration of heat rays
from the surface of the earth. Methane, chlorofluorocarbons and dinitrogen monoxide have similar
characteristics. When the amounts of these gases in the atmosphere increase, heat that normally escapes
through the atmosphere remains near the earth's surface, thus increasing the temperature of air. The
degree of the effect to the earth caused by the atmospheric temperature rise due to these gases is
numerically expressed by global warming potential (GWP).

All models combine master units and slave units or master units, slave units and Plus units.
All models use a new refrigerant with low ozone destruction potential and global warming potential to
minimize environmental loads (see Feature (1)).
With a value of 1 given to the ozone destruction potential and global warming potential of the R11
refrigerant, smaller values mean less environmental impact.
Use of new refrigerant (R-407C) that does not deplete the ozone layer

Reduction of refrigerant charge volume (approx. 75% as compared to R22-refrigerant unit with 20 HP
and 5-m pipe)
--- Mainly by elimination of function units, simplification of refrigerant circuits and reduction of internal
volume.
Dramatically improved flexibility and ease of field installation by function-unit-less structure
--- Simpler piping work at installation sites
--- Reduced unit installation area
