<P>PROBLEM TO BE SOLVED: To improve comfort of a person in the space to be air-conditioned during defrosting operation, and to improve efficiency in the defrosting operation. <P>SOLUTION: Indoor units 40a and 40b include a casing 41 and a human detection sensor group 46, and are connected to an outdoor unit 20 through refrigerant connection pipes P5 and P6. In the casing 41, outlets 41aa-41ad, 41ba-41bd are formed for blowing out the air-conditioned air into an air conditioning room RA. The human detection sensor group 46 detect whether there is a person in the air-conditioning room RA. A control part 62 of a general controller 60, during defrosting operation for removing the frost formed on an outdoor heat exchanger 23, determines the flow rate of the refrigerant that flows the indoor units 40a and 40b based on the result of the human detection sensor group 46. A refrigerant flow rate control part 53 of the indoor units 40a and 40b performs refrigerant flow rate control for the indoor units 40a and 40b, based on the flow rate of the refrigerant determined by the control part 62. <P>COPYRIGHT: (C)2012,JPO&INPIT |
