Abstract: 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.

Abstract: A model receives a target demand curve as an input and outputs an optimized control sequence that allows equipment within a physical space to be run optimally. A thermodynamic model is created that represents equipment within the physical space, with the equipment being laid out as nodes within the model according to the equipment flow in the physical space. The equipment activation functions comprise equations that mimic equipment operation. Values flow between the nodes similarly to how states flow between the actual equipment. The model is run such that a control sequence is used as input into the neural network; the neural network outputs a demand curve which is then checked against the target demand curve. Machine learning methods are then used to determine a new control sequence. The model is run until a goal state is reached.

Abstract: A networked HVAC system is implemented as part of a multi-unit dwelling. At least one HVAC unit is installed within each unit of the multi-unit dwelling. Each individual HVAC unit includes a localized HVAC unit controller, which is connected to an external network. The HVAC unit controller also can be connected to any other controllable HVAC devices in the unit, such as an exhaust fan. The HVAC system addresses the open-loop issue by monitoring temperature, air flow, humidity, air pressure, occupancy, window open/close state, and HVAC units of all units in a multi-unit dwelling, as well as common areas, and optimizing operating parameters to minimize wide swings in operational states and managing the overall system of multiple units/common areas so that energy usage and temperature/ventilation control is optimized. The HVAC system also enables learning and predictive modeling for adapting to real-time and anticipated condition requirements within each zone.
