A control unit 40 acquires acceleration \u03b1 sensed by an acceleration sensor 31, and if the control unit 40 determines that acceleration \u03b1 does not equal zero, the control unit 40 again acquires acceleration \u03b1. Each computer includes one or more software modules which present the resources of the computers as a virtual NUMA machine. The heating medium circuit includes at least one room heating device that releases the heat of the heating medium heated in the heating medium\u2014refrigerant heat exchanger into the room, and circulates the heating medium between the room heating device and the heating medium\u2014refrigerant heat exchanger. The indicator is moveable from the internal area of the container to an external area. The purge fluid delivery system provides a flow path for the purge fluid which is isolated from the flow of the heating fluid through the plates.
