Abstract
The INTERIOR COMFORT HVAC USER-FEEDBACK CONTROL SYSTEM AND APPARATUS transforms qualitative feedback received from a user/occupant into a “comfort map,” or modifications thereto, a comfort map being defined at least in part by one or more comfort event windows. The comfort map data is used to determine a temperature setpoint sequence that avoids regions of the map corresponding to known and/or predicted regions of user discomfort.
Claims36
A method for HVAC control of a thermostat, the method comprising:
- receiving comfort event data;
- accessing a first comfort map that includes time, temperature, and comfort characteristic data for a comfort map episode;
- updating the first comfort map with comfort event window data determined based on the comfort event data that includes a time data and a temperature increase or decrease request and comfort map reference data including a time/temperature pair and an associated comfort characteristic;
- deriving a temperature trajectory from the updated comfort map;
- and
- executing the temperature trajectory for the remainder of the episode,
- wherein executing the temperature trajectory includes avoiding a cool set of the updated comfort map when the HVAC system is in a heating mode or avoiding a warm set of the updated comfort map when the HVAC system is in a cooling mode.
An apparatus for HVAC control, comprising:
- a processor;
- and
- a memory disposed in communication with the processor and storing processor-issuable instructions to:
- receive comfort event data;
- access a first comfort map that includes time, temperature, and comfort characteristic data for a comfort map episode;
- update the first comfort map with comfort event window data determined based on the comfort event data that includes a time data and a temperature increase or decrease request and comfort map reference data including a time/temperature pair and an associated comfort characteristic;
- derive a temperature trajectory from the updated comfort map;
- and
- execute the temperature trajectory for the remainder of the episode, wherein the instructions to execute the temperature trajectory includes instructions to avoid a cool set of the updated comfort map when the HVAC system is in a heat mode and/or avoid a warm set of the updated comfort map when the HVAC system is in a cool mode.
