EQUIPMENT FAULT DETECTION, DIAGNOSTICS AND DISAGGREGATION SYSTEM

摘要

A system for fault detection and diagnostics of equipment. The system may also be capable of disaggregation and/or virtual submetering of energy consumption by equipment, such as that of heating, ventilation and air conditioning, lighting, and so forth, in a building. Vibration and current sensors, along with one or more algorithms, may be utilized for fault detection and diagnostics of equipment. Models may be developed to aid in deducing energy consumption of individual components of equipment, and the like, for a building.

1. A roof top unit fault detection and diagnostics appliance comprising:
a computer for connection to a roof top unit; a vibration sensor for attachment to a roof top unit and connected to the computer; and one or more current sensors for connection to a power feed to the roof top unit and connected to the computer; and wherein: the vibration sensor provides signals representing vibration at the roof top unit to the computer; the one or more current sensors provide signals representing total power consumption by the roof top unit; and the signals representing vibration and total power consumption are analyzed to check for certain types of degradation and malfunction of the roof top unit.
