8) ones designed for vehicles and other means of transport,

9) ones so structured as to have a duct at suction/exhaust outlet of a heat-exchanger of the outdoor unit,

10) ones so structured as to have a thermal storage tank dedicated for cooling (including a thermal storage tank for cooling-cum-heating),

11) ones designed for highly gas-tight/heat-insulating housing, and so structured as to send air to multiple rooms through a branched duct and operate interlocked with ventilation devices,

12) ones so structured as to have compressors, air blowers and other main components powered by electricity generated from a dedicated solar cell module,

13) ones having floor heating function or hot-water supply function,

14) among separate type air conditioners so structured as to connect two or more indoor units to one outdoor unit, ones using heat absorbed by space cooling for space heating,
