To provide a heat source system which includes a refrigerant sensor and achieves user's convenience in a period from the time when the refrigerant sensor detects refrigerant leakage until the time when the refrigerant sensor is replaced.SOLUTION: A heat source system includes: a refrigerant sensor which detects refrigerant leakage; a refrigerant leakage detection part which maintains an abnormality detection state until the refrigerant sensor is replaced in a case where the refrigerant sensor detects refrigerant leakage; and an operation control part which shifts an operation mode of the heat source system to an emergency operation mode in which emergency operation can be conducted when detecting occurrence of a predetermined emergency operation mode shifting event in the abnormality detection state.SELECTED DRAWING: Figure 2 【課題】冷媒センサを備える熱源システムで、冷媒センサが冷媒漏れを検知した後、その冷媒センサが交換されるまでの間のユーザの利便性を図る。【解決手段】熱源システムが、冷媒漏れを検知する冷媒センサと、前記冷媒センサが冷媒漏れを検知した場合、前記冷媒センサが交換されるまで異常検知状態を維持する冷媒漏れ検知部と、前記異常検知状態にて、所定の応急運転モード移行事象の発生を検知した場合、熱源システムの運転モードを応急運転可能な応急運転モードに移行させる運転制御部と、を備える。【選択図】図２
