The invention claimed is: 1. An air conditioning system comprising, a humidity controller and an air conditioner and supplying to the same room air dehumidified by the humidity controller and air refrigerated by the air conditioner; and an arithmetic section for calculating at least one of an estimated operating efficiency of the humidity controller, an estimated operating frequency of the humidity controller, and a ratio between a outdoor air humidity and a target humidity of the air conditioning system, wherein: the air conditioner is configured to be capable of operating to dehumidify air during refrigeration thereof by condensing moisture in the air; and a normal operation to dehumidify air by the humidity controller alone and a simultaneous dehumidifying operation to dehumidify air by the humidity controller and the air conditioner are configured to be switchable to one another based on a result of the calculation by the arithmetic section. 2. An air conditioning system according to claim 1, wherein the arithmetic section calculates the estimated operating efficiency of the humidity controller when air is dehumidified by the humidity controller alone, and the normal operation is performed when the operating efficiency of the humidity controller estimated by the arithmetic section is equal to or more than a reference operating efficiency, while the simultaneous dehumidifying operation is performed when the operating efficiency of the humidity controller estimated by the arithmetic section is less than the reference operating efficiency. 3. The air conditioning system according to claim 2, wherein during the simultaneous dehumidifying operation, a dehumidifying capacity of the humidity controller is adjusted such that the operating efficiency of the humidity controller becomes the reference operating efficiency. 4. The air conditioning system according to claim 1, wherein: the humidity controller is configured to dehumidify outdoor air and supply the dehumidified air to the room; and the normal operation and the simultaneous dehumidifying operation are switched to one another depending on the ratio between a outdoor air humidity and a target humidity of the air conditioning system. 5. The air conditioning system according to claim 1, wherein: the humidity controller comprises a refrigerant circuit having a compressor of variable capacity, and adsorbing members on which an adsorbing agent is supported, the humidity controller being configured to dehumidify air that comes into contact with the adsorbing agent of the adsorbing members refrigerated by the refrigerant of the refrigerant circuit; the arithmetic calculates the estimated operating efficiency of the humidity controller when air is dehumidified by the humidity controller alone; and the normal operation is performed when the operating efficiency of the humidity controller estimated by the arithmetic section is equal to or more than a reference operating efficiency, while the simultaneous dehumidifying operation is performed when the operating efficiency of the humidity controller estimated by the arithmetic section is less than the reference operating efficiency. 6. The air conditioning system according to claim 1, wherein: the humidity controller comprises a refrigerant circuit having a compressor of variable capacity, and adsorbing members on which an adsorbing agent is supported, the humidity controller being configured to dehumidify air that comes into contact with the adsorbing agent of the adsorbing members refrigerated by the refrigerant of the refrigerant circuit; the arithmetic calculates the estimated operating frequency of the humidity controller when air is dehumidified by the humidity controller alone; and the normal operation is performed when the operating frequency of the humidity controller estimated by the arithmetic section is less than an upper limit frequency, while the simultaneous dehumidifying operation is performed when the operating frequency of the humidity controller estimated by the arithmetic section is equal to or more than the reference operating frequency. 7.
