HVAC system remote monitoring and diagnosis
First Claim
1. A method of operating a heating, ventilation, or air conditioning (HVAC) monitoring system, the method comprising:
- at a remote monitoring apparatus, the remote monitoring apparatus having a processor and a memory, periodically receiving frames of data from a local monitoring device installed at a building, wherein the remote monitoring apparatus is geographically separate from the building, and wherein each individual frame of the frames of data corresponds to a window of time and each individual frame includes;
(i) time domain current data based on a measured aggregate current supplied to a plurality of components of an HVAC system of the building; and
(ii) frequency domain current data based on the measured aggregate current;
storing current data in the memory of the remote monitoring apparatus for each individual frame of the frames of data, wherein the current data includes (i) a single time domain current value based on the time domain current data and (ii) the frequency domain current data;
using the processor of the remote monitoring apparatus, based on the stored current data and exclusive of individual current data from a plurality of individual current sensors respectively configured for monitoring each of the plurality of components of the HVAC system, determining an individual contribution of a first component of the plurality of components of the HVAC system to the measured aggregate current;
transmitting information to an HVAC manufacturer, wherein the information is based on the stored current data;
selectively identifying a problem occurring in the first component using the determined individual contribution; and
in response to the problem being identified, selectively transmitting an alert message.

Abstract
A method of operating a heating, ventilation, or air conditioning (HVAC) monitoring system includes, at a remote monitoring apparatus, receiving and storing frames of data from a local monitoring device installed at a building. Each of the frames includes time domain current data based on a measured aggregate current supplied to a plurality of components of an HVAC system of the building and frequency domain data based on the measured aggregate current. The method includes, based on the frequency domain current data and exclusive of individual current data from a plurality of individual current sensors, determining an individual contribution of a first component of the HVAC system to the measured aggregate current. The method includes transmitting information based on the stored current data to an HVAC manufacturer. The method includes, if a problem is identified with the first component using the determined individual contribution, transmitting an alert message.
