MULTI-CHAMBER TYPE AIR CONDITIONER

摘要

PURPOSE:To provide a multi-chamber type air conditioner in which a cooling operation and a heating operation can be freely selected for every indoor device under a freezing cycle, an accumulation of refrigerant in an indoor heat exchanger of the stopped indoor device is prevented under a less-expensive specification and then a desired cooling or heating capability can always be assured. CONSTITUTION:A multi-chamber type air conditioner is provided with an indoor device operating state sensor 21 and an indoor device controlling means 22 for use in sensing whether an indoor device 6 performs a cooling operation and a heating operation or the indoor device 6 is stopped. The indoor device control means 22 fully closes an expansion valve 7 in respect to the indoor device 6 being stopped in reference to a result of sensing operation of the indoor device operating state sensor 21, closes either the first solenoid valve 12 or the second solenoid valve 13 connected to a high voltage side and opens either one of them connected to a low voltage side.
