Daikin Japan to launch R32 in commercial ac

JAPAN: Already being deployed in its residential air conditioning units in Japan, the low GWP, HFC refrigerant R32, is now being introduced by Daikin in a range of commercial units for the first time.

It was 12 months ago that Daikin announced the introduction of R32 in all residential models sold in Japan. Daikin India was next to adopt R32 in its Ururu Sarara units, followed in June this year by Daikin Europe announcing the arrival of R32 in small splits this autumn.

While the emergence of R32 products in Europe is still awaited, Daikin Japan has today announced that it will introduce of a range of Five Star Zeas commercial units in Japan on November 1.

The new units are in sizes up to 6hp and feature a range of indoor units. In addition to the adoption of R32, a key feature of the new design is Daikin’s PLR (pressure loss reduction) refrigerant circuit which is said to optimise the use of R32.

R32 is a single component, zero ODP gas with a GWP around a third that of R410A - the refrigerant it replaces. It is classified as A2L, or mildly flammable, under ASHRAE classifications.
