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 unit of mechanical impedance is the mechanical ohm; in SI units this is N-s/m, or Kg/s. The rotational impedance analogy describes rotating mechanical systems and gives rise to the idea of rotational impedance. The unit of rotational impedance in the SI system is N-m-s/rad. The acoustical impedance analogy gives rise to the idea of acoustic impedance. The unit of acoustic impedance is the acoustic ohm; in SI units this is N-s/m. Mobility analogies, also called the Firestone analogy, are the electrical duals of impedance analogies. That is, the effort variable in the mechanical domain is analogous to current (the flow
