    • PROBLEM TO BE SOLVED: To provide an air conditioner allowing an additional indoor unit to be easily installed and achieving cooling corresponding to a hot spot. SOLUTION: This air conditioner 100 includes a branch piping closing means 19 disposed in liquid branch piping 15b, first connection piping 41 connected with the liquid branch piping 15b between a refrigerant distributing means 14 and the branch piping closing means 19, a first refrigerant circuit opening/closing means 110 disposed in the first connection piping 41, a header closing means 111 disposed in gas branch piping 27b connected with the liquid branch piping 15b, second connection piping 42 connected with the gas branch piping 27b between the header closing means 111 and a refrigerant merging means 17, and a second refrigerant circuit opening/closing means 112 disposed in the second connection piping 42. The first connection piping 41 and the second connection piping 42 is communicated with each other. COPYRIGHT: (C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an air conditioning system which hardly falls into inaility to provide sufficient sensible heat capacity as the entire system, and capable of maintaining the indoor temperature and humidity by a remaining refrigerant circuit system even when one refrigerant circuit system is failed. SOLUTION: The air conditioning system comprises a refrigerant circuit system 10a constituted by successively connecting a compressor 21, an outdoor heat exchanger 22, an expansion valve 11 and an indoor heat exchanger 12 to each other, a refrigerant circuit system 10b constituted by successively connecting a compressor 31, an outdoor heat exchanger 32, an expansion valve 13, and an indoor heat exchanger 14 installed in the same room 5 in which the indoor heat exchanger 12 is installed to each other, an indoor unit air supply means 16, and a temperature/humidity detection means 51 in the room 5. In addition, an indoor unit control means 15 to perform predetermined dehumidifying operation in the indoor heat exchangers 12 and 14 of at least one of the refrigerant circuit systems 10a and 10b based on the detected temperature and the detected humidity by the temperature/humidity detection means 51.
