The purpose of the present invention is to more efficiently cool exhaust heat, of an apparatus or the like that emits heat, by preventing a situation where a gas-phase medium is cooled and turns into a liquid-phase medium and thereby transfer of the gas-phase medium is hindered. For this purpose, a cooling system includes a heat receiving means for receiving a gas heated by heat emitted by an electronic apparatus and changing a liquid-phase heat medium into a gas-phase heat medium. a heat radiation means for cooling the gas-phase heat medium so as to be changed into the liquid-phase heat medium. a first transfer means for transferring the gas-phase heat medium from the heat receiving means to the heat radiation means. and a second transfer means for transferring the liquid-phase heat medium from the heat radiation means to the heat receiving means. wherein at least part of the first transfer means is heated by the heat emitted by the electronic apparatus.

A central information management console provides for real time management of airflow across an information handling system or across multiple information handling systems within one or multiple racks within an environment by estimating and prioritizing the volumetric airflow needs of each information handling system within the environment. Each information handling system or group of information handling systems may be given a priority setting based on one or more criteria and volumetric airflow may be provided based on the priority setting and a selected balancing option. Metrics and sensor readings are received by the central information management console in real time or at intervals to use in determining the amount of volumetric airflow to provide to each information handling system so as to balance volumetric airflow for efficient operation of the environment and to maintain volumetric airflow so as not to exceed a volumetric airflow limit.
