Filed:

May 21, 2021

Appl. No.:

17/326496

Inventors:

- Los Angeles CA, US
John Ko - Los Angeles CA, US

International Classification:

F24F 11/63
G05B 13/02
G05B 13/04

Abstract:

A system for climate control comprises a controller, comprising a processor and a non-transitory computer-readable medium with instructions stored thereon, a plurality of sensors communicatively connected to the controller, and at least one HVAC component communicatively connected to the controller, wherein the instructions, when executed by the processor, perform steps comprising receiving sensor data from at least one sensor of the plurality of sensors, executing a machine learning model using the received sensor data as inputs, calculating a predicted temperature, humidity, or occupancy state from the machine learning model, and sending a control instruction to the at least one HVAC component based on the calculated temperature, humidity, or occupancy state. A method for training a machine learning algorithm for a climate control system and a method for HVAC control in a building are also described.

International Classification:

F24F 11/64
G05B 19/042
F24F 11/74

Abstract:

A system for controlling airflow into a single room includes a duct having a controllable damper, fluidly connected to the room, a controller connected to the damper, configured to open and close the damper, at least one sensor communicatively connected to the controller, positioned in the room and configured to measure a parameter in the room, at least one portable computing device communicatively connected to the sensor and the controller, and control logic stored as instructions on a non-transitory computer readable medium, the instructions configured to open and close the damper in response to a measurement received from the at least one sensor. A method for controlling a damper in a duct fluidly connected to a room is also described.

H05B 37/02

Abstract:

A hotel guest detection system includes an HVAC system, a thermostat communicatively connected to the HVAC system, at least one processing unit, at least one motion sensor, at least one door sensor, and at least one bed sensor configured to determine whether or not a guest is in a bed. The bed sensor, thermostat, and bed sensor are communicatively connected to the processing unit, and the processing unit is configured to manipulate a setting of the thermostat based on measurements obtained from the bed sensor and the motion sensor. A method of detecting guests in a hotel room is also described.
