Publication number: 20240035699Abstract: A heating, ventilation, and air conditioning (HVAC) system includes a network of wireless remote climate sensors to develop a complete heat map of an enclosed space. The remote climate sensor is configured to collect temperature and humidity data on a zone of the enclosed space. The HVAC system uses a network of these sensors to obtain data points across the enclosed space. The resulting heat map is used by the HVAC system to determine where to direct air in the enclosed space. By comparing the temperature and humidity at a specific remote climate sensor with the user's desired temperature and humidity, the HVAC system can decide whether to increase or decrease the air flow through a variable damper that is located near the remote climate sensor. By conducting this analysis throughout the enclosed space and making incremental adjustments to the air flow in hot and cold spots in the enclosed space, the disclosed HVAC system provides even comfort to the user along with reduced energy consumption.Type: ApplicationFiled: October 6, 2023Publication date: February 1, 2024Inventors: Keith R.

Patent number: 11719460Abstract: A network of wireless remote climate sensors in a heating, ventilation, and air conditioning (HVAC) system permits the creation of personalized microclimates within an enclosed space. In addition to collecting temperature and humidity data, the wireless remote climate sensors can detect whether the enclosed space is occupied by a human. Human detection is made possible by optional cameras, microphones, and gas sensors on the wireless remote climate sensors. As the human moves throughout the enclosed space, the HVAC system is able to track the human's movement using the wireless remote climate sensors. The HVAC system may adjust airflow to different portions of the enclosed space based on the human's location. The result is an efficient use of system resources to keep users at their ideal temperature.Type: GrantFiled: December 21, 2021Date of Patent: August 8, 2023Assignee: Lennox Industries Inc.Inventors: Keith R.
