摘要： PROBLEM TO BE SOLVED: To provide an air conditioner capable of improving heating performance by continuing indoor heating even during defrosting an outdoor heat exchanger, though in performing a defrosting operation in a conventional air conditioner, a heating operation at an indoor machine side is temporarily stopped until the defrosting is terminated, and the heating of the indoor air by the indoor-side heat exchanger must be stopped, which causes degradation of average heating performance. SOLUTION: In this air conditioner where a plurality of heat source machines and at least one or more indoor machines are connected through a flow channel switching valve device which constantly keeps a prescribed connection pipe under a low pressure and keeps the other prescribed connection pipe under a high pressure in operation, the plurality of heat source machines are respectively provided with frost formation detecting means, the defrosting operation is performed only in the heat source machine where frost formation is detected, when a state of frost formation is detected in any one of the heat source machines, and the other heat source machines continue the heating operation.
