Mechanical room (see: mechanical floor). Mechanical rooms typically house the following equipment: Equipment in mechanical rooms is often operated and maintained by a stationary engineer or a maintenance technician. Modern buildings use control systems to manage HVAC cycles, lighting, communications, and life safety equipment. Often, the control system hardware is located in the mechanical room and monitored or accessed remotely. Rooms with only electrical or electronic equipment are not considered mechanical rooms but are instead called electrical rooms. Mechanical room A mechanical room or a boiler room is a room or space in a building dedicated to the mechanical equipment and its
Mechanical–electrical analogies making up the power conjugate pair as an "effort" variable and a "flow" variable. The effort variable in an energy domain is the variable analogous to force in the mechanical domain. The flow variable in an energy domain is the variable analogous to velocity in the mechanical domain. Power conjugate variables in the analog domain are chosen that bear some resemblance to force and velocity. In the electrical domain, the effort variable is voltage and the flow variable is electrical current. The ratio of voltage to current is electrical resistance (Ohm's law). The ratio of the effort variable to the
