hotel load
Language: English
Part of speech: noun
Pronunciation: ipa: /həʊˈtɛl ləʊd/
ipa: /hoʊˈtɛl loʊd/
Forms: form: hotel loads
Etymology: Possibly from the fact that this type of electrical load relates to the human occupancy aspects of a vehicle such as air conditioning and lighting, analogous to the features of a hotel.
Senses: examples: text: Auxiliary power units provide electricity to all systems aboard a ship except main propulsion. These systems include hotel services (lighting, plumbing, and pumps for water), […] Cruise ships […] have big hotel loads; hence, quiet, unobtrusive fuel cell auxiliary power units may be particularly suited for this type of ship.

text: As well as providing the propulsive power, the batteries also have to provide power for the operation of sensors, weapons and auxiliary machinery and those for habitability, ventilation and air-conditioning of the crew. They constitute a steady drain on the batteries, governed by the length of time submerged, and together are termed the Hotel Load.

text: The "hotel load" (i.e., the electricity required for people), in watts per square foot, was multiplied by the module area[…].

text: [I]n heavy-duty, long haul trucking as much as 40 percent of engine run time is spent idling to provide auxiliary (nonmotive) power. Many of these energy demands are "hotel" loads, for example, heating or cooling a sleeping/living compartment, refrigerators, stoves, entertainment systems, and so forth.

text: Here the total electrical power consumed by the vehicle, P, is equal to the sum of the propulsion power, P#95;#123;prop#125; and hotel load, H. Hotel load is simply the power consumed by all subsystems other than propulsion.
