Packaged Air-Conditioners Suitable for Cold Areas
Annual domestic (Japanese) shipments of packaged air-conditioners were 624,000 in 1999, and reached 808,000 in 2005, showing a favourable increase. Of the shipped packaged air-conditioners, those intended for shops and offi ces accounted for 81%. However, shipments of packaged airconditioners for Hokkaido and Tohoku District amounted to over 47,000 in 2005, and are also on the increase recently. Heat pump air-conditioners have been almost inadequate, because their heating capacity is reduced with falling outside air temperature, which requires electric heaters and stoves to supplement the insuffi cient heating capacity of conventional heat pump air-conditioners.
