Abstract: According to an aspect, a method of thermal management includes capturing one or more thermal images within a temperature-controlled space, using a thermal imaging camera. One or more sources of radiant heat are identified within the temperature-controlled space based on the one or more thermal images. A heat level variation of the one or more sources is determined with respect to an ambient temperature of the temperature-controlled space. A control action of a heating, ventilation, and air-conditioning system is triggered in response to the heat level variation.

Abstract: Disclosed is an HVAC system with networked HVAC zone sensors, and HVAC zone controllers communicating with portable smart devices over personal area networks, wherein the portable smart devices are registered with an HVAC controller and assigned to device groups, each of the HVAC zone controllers is paired with each of the portable smart devices, each of the HVAC zone controllers scans to determine whether, and how many of, the portable smart devices are within communication range, the HVAC controller communicates with each of the HVAC zone controllers to determine the results of the scans, and the HVAC controller controls the HVAC system based on the results accounting for how many of the portable smart devices detected by the HVAC zone controllers are subsumed under one or more of the device groups.
