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 in one paper to model the cochlea of the human ear. Another condition required of electrical systems for the application of the lumped element model is that no significant fields exist outside the component since these can couple to other unrelated components. However, these effects can often be modelled by introducing some virtual lumped elements called strays or parasitics. An analog of this in mechanical systems is vibration in one component being coupled to an unrelated component. The power conjugate variables are a pair of variables whose product is power. In the electrical domain the power conjugate variables chosen are
