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
