AIR-CONDITIONING SYSTEM

PROBLEM TO BE SOLVED: To provide an air-conditioning system capable of suppressing deterioration in the temperature of a fuel cell in the failure of an air-conditioning functional component.SOLUTION: An air-conditioning system 100 includes: an FC circuit 1; an air-conditioning circuit 2 through which fluid for cooling to be used for the air-conditioning of a vehicle flows; and a control device 5. The air-conditioning system 100 includes: a three-way valve 23 for switching a cooperation mode operation in a state that the FC circuit 1 and the air-conditioning circuit 2 are communicated and an independent mode operation in a state that the FC circuit and the air-conditioning circuit 2 are separated. The control device 5 executes at least the cooperation mode operation and the independent mode operation by controlling the operation of the three-way valve 23, and determines the presence/absence of a failure about at least one component among failure determination object components including an air-conditioning pump, the three-way valve 23, a temperature sensor for a fuel cell and a temperature sensor for air-conditioning. The control device 5 executes the operation stop or the independent mode operation of the air-conditioning pump when determining the presence of the failure of at least one of the failure determination object components.SELECTED DRAWING: Figure 1 【課題】空調機能部品の故障時に、燃料電池の温度低下を抑制できる空調システムを提供する。【解決手段】空調システム１００は、ＦＣ回路１と、車両の空調に用いられる冷却用流体が流れる空調用回路２と、制御装置５と、を備える。空調システム１００は、ＦＣ回路１と空調用回路２とを連通させた状態の連携モード運転とＦＣ回路１と空調用回路２とを切り離した状態の独立モード運転と、を切り換える三方弁２３を備える。制御装置５は、三方弁２３の作動を制御して連携モード運転と独立モード運転とを少なくとも実施し、空調用ポンプ、三方弁２３、電池用温度センサ及び空調用温度センサを含む故障判定対象部品のうち、少なくとも一つの部品について故障の有無を判定する。制御装置５は、故障判定対象部品の少なくとも一つについて故障であると判定した場合は、空調用ポンプの運転停止または独立モード運転を実施する。【選択図】図１
