Abstract: The smart HVAC manifold system for servicing air conditioning systems is designed to dynamically manage the data acquisition process and to measure and calculate the performance indicators and output as the load conditions and or equipment operation change taking into account variables in the installation that can impact performance. Both visually and by a very specific data set the performance of the equipment and the installation can quickly be assessed and specific problems identified along with suggestions of typical faults or problems that may need addressed by the technician. The smart HVAC manifold system provides a means of quickly and electronically handling the manual data acquisition process which would include component and or system model and serial numbers, equipment location (GPS tagging), customer name, environmental conditions that effect performance and performance measurement (weather data and elevation), and supports photo, voice and text documentation.
