CURRENT BASED AIR FILTER DIAGNOSTICS AND MONITORING

摘要

A system and method for a heating, ventilation, and air conditioning (HVAC) system of a building is provided. A monitoring device installed at the building is configured to measure a current supplied to the HVAC system and transmit current data based on the measured current. The monitoring system includes a monitoring server, located remotely from the building, configured to receive the transmitted current data and, based on the received current data, determine an average motor current over a predetermined time period and determine whether a failure has occurred in an air filter of the HVAC system based on a comparison of the average motor current with a predetermined threshold. The monitoring server generates a notification based on the comparison indicating that the failure has occurred in the air filter.

1. A monitoring system for monitoring a heating, ventilation, or air conditioning (HVAC) system of a building, the monitoring system comprising:
a monitoring server, located remotely from the building, configured to (i) receive current data from a monitoring device at the building that measures a current supplied to the HVAC system, (ii) determine an average motor current drawn by a circulator blower motor of the HVAC system over a predetermined monitoring time period based on the received current data, (iii) compare the average motor current drawn by the circulator blower motor with a threshold, (iv) determine whether an air filter of the HVAC system needs to be replaced based on the comparison, and (v) generate a notification based on the determination indicating that the air filter needs to be replaced.
