Airplane cabin environment management

摘要

A system has a power source 203 connected to power access points 205 and at least one environmental control system 201. A threshold compare device 206 is effective to compare the proportional load on the environmental control systems 201 to a preset threshold. If the threshold is exceeded, unused power access points 205 are disabled. This prevents such access points 205 from placing additional loads on the environmental control systems 201. Conversely, when the proportional load on the environmental control systems 201 drops below a preset threshold, power can be restored to the disabled power access points 205. A master control unit can monitor the load on the environmental control systems 201 and either or both the environmental conditions in environment zones 202 or the power loading of the power access points 205 and determine whether to disable 204 unused power outlets.
