PROBLEM TO BE SOLVED: To prevent an increase of a leakage current resulting from refrigerant oil of an existing air conditioning system remaining in an air conditioning system after renewing part of structural equipment of the existing air conditioning system, while utilizing a refrigerant pipe for the existing air conditioning system as an existing refrigerant pipe. SOLUTION: The air conditioning system 101 constructed with an indoor unit 102 renewing an outdoor unit 2 of the existing air conditioning system 1 comprises refrigerant communication pipes 6 , 7 for the existing air conditioning system 1, a sealed compressor 121 using refrigerant oil having higher electric insulation than refrigerant oil for an existing compressor 21, and a current counteracting device 128c for counteracting the leakage current from a motor 121b of the compressor 121.
