PROBLEM TO BE SOLVED: To provide an air conditioning system for detecting a refrigerant leakage by considering a risk at the refrigerant leaking time of an individual air conditioning system.SOLUTION: An air conditioning system 2 comprises an estimation unit 213 for estimating the degree of a coolant leakage amount from a refrigerant circuit; a determination unit 212 for determining one decision level according to installation information, from among a plurality of determination levels different in the degree of a coolant leakage amount; and a detection unit 214 for detecting a coolant leakage by comparing the degree of the coolant leakage amount estimated by the estimation unit 213 and one determination level determined by the determination unit 212.SELECTED DRAWING: Figure 2 |
