<P>PROBLEM TO BE SOLVED: To provide a technology that reduces the occurrence of idling of an air conditioning pump disposed in an air conditioning circuit, as a first purpose. <P>SOLUTION: An air conditioning system includes: a cooling circuit having a cooling pump; the air conditioning circuit having the air conditioning pump; a switching part for switching between a connected state, in which a refrigerant circulates between the cooling circuit and the air conditioning circuit, and an unconnected state, in which the refrigerant does not circulate between the cooling circuit and the air conditioning circuit; and a controller for controlling the air conditioning system. The controller drives the cooling pump at the rotation speed higher than a predetermined value irrespective of any power generation state of a fuel battery while driving the air conditioning pump in the connected state when it is determined that the idling is caused in the air conditioning pump, or when a predetermined condition in which idling may be caused is met. <P>COPYRIGHT: (C)2012,JPO&INPIT |
