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 and consequently is usually credited with founding the impedance analogy. This was the earliest mechanical–electrical analogy. However, the term "impedance" was not coined until 1886, long after Maxwell's death, by Oliver Heaviside. The idea of complex impedance was introduced by Arthur E. Kennelly in 1893, and the concept of impedance was not extended into the mechanical domain until 1920 by Kennelly and Arthur Gordon Webster. Maxwell's purpose in constructing this analogy was not to represent mechanical systems in terms of electrical networks. Rather, it was to explain electrical phenomena in more familiar mechanical terms. As electrical phenomena became better understood
