Outline of New Series Products

In addition to the use of a new refrigerant (R407C), the new series products incorporate a function-unit-less structure
for significantly improved flexibility and ease of installation.

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).

„ Dramatically improved flexibility and ease of field installation by function-unit-less structure
„ Simpler piping work at installation sites

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.
