Abstract

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.

First claim

What is claimed:

1. A method for establishing a personalized microclimate in an enclosed space, the method comprising:
storing a plurality of climate profiles and an arbitration logic comprising a set of rules for application when there is detection of more than one human in a first zone of the enclosed space, wherein each climate profile comprises a desired temperature, a desired humidity, and at least one user identifier;
storing a first preemption value associated with a first climate profile and a second preemption value associated with a second climate profile;
applying the arbitration logic to determine operation of a first variable damper located in the first zone based, at least in part, on a comparison of the first preemption value to the second preemption value;
receiving, from a first wireless remote sensor, an identification of a human located in the first zone;
matching the identification of the human in the first zone with a first user identifier in first a climate profile;
comparing a desired temperature saved in the first climate profile with a temperature measurement received from a wireless remote sensor located in the first zone; and
instructing the first variable damper to alter the flow of air into the first zone if the temperature and humidity measurements from the first zone differ from the desired temperature saved in the first climate profile.

2. The method of claim 1 , further comprising instructing a second variable damper to decrease the flow of air into a second zone of the enclosed space if the first variable damper is instructed to increase the flow of air into the first zone.

3. The method of claim 1 , further comprising:
receiving, from the first wireless remote sensor, an identification of a second human located in the first zone of the enclosed space;
matching the identification of the second human in the first zone with a second user identifier in a second climate profile; and
applying an arbitration logic to determine that the desired temperature and desired humidity in the second climate profile should be ignored.

4. The method of claim 1 , further comprising:
determining that the identification of the human in the first zone does not match a first user identifier in first a climate profile
retrieving a default climate profile comprising a desired temperature and a desired humidity to apply when the human is unidentified; and
instructing the first variable damper to alter the flow of air into the first zone if the temperature and humidity measurements from the first zone differ from the desired climate settings in the default climate profile.

5. The method of claim 1 , wherein the identification of the human located in the first zone of the enclosed space comprises an image of the human captured in the first zone.

6. The method of claim 1 , wherein the identification of the human located in the first zone of the enclosed space comprises a voice sample of the human captured in the first zone.

7. The method of claim 1 , wherein the identification of the human located in the first zone of the enclosed space comprises the detection of a Bluetooth enabled smart device associated with the human.
