An HVAC control system having a cloud-based optimization engine in communication with a local building hub that interfaces with the building HVAC system and room units. The cloud-based optimization engine implements an optimal and predictive control strategy to integrate occupancy prediction, weather forecasting, and modeling of indoor infection risk, indoor air quality, and building energy consumptions. The control strategy includes a model-based predictive control and a model-free reinforcement learning approach. The control strategy considers outdoor weather (both thermal and air quality) conditions, indoor occupancy and requirements for IAQ and infectious risk reduction to decide whether outdoor air should be introduced and how much fresh air will be introduced into the space. Communications with the building hub allow the local HVAC unit to be driven according to the optimization plan. Individual room sensing units can provide local sensor data to the cloud-based optimization engine.

A system including a motor of a compressor system and a motor controller is disclosed. The controller is configured to selectively allocate voltage between a first winding and second winding of the compressor motor. Allocation of voltage biases the first winding of the compressor motor over the second winding. The controller selectively allocates voltage to bias windings in response to a command to transition the HVAC control system from the first operating mode to a second operating mode. The controller further selectively allocates voltage to bias windings in response to received sensor data, such as temperature, pressure, or time data. The controller biases voltages for one or more operating modes or load intervals of the system.

This invention provides an adaptive HVAC operation monitoring system, relating to the field of HVAC control system technology. It collects data on zone temperature, air and water parameters, flow rate, pressure, and actuator status; predicts the free drift trajectory of temperature in each zone under unchanged basic control conditions; and calculates the comfort boundary arrival time. It calculates the extension sensitivity of actuators to the comfort boundary arrival time of each zone at different operating times, constructing a comfort boundary arrival time tensor. Based on this tensor, it solves for the control quantity that increases the minimum comfort boundary arrival time, and identifies structural capability degradation by comparing theoretical and actual extension values. After degradation occurs, it performs capability reconstruction compensation based on the remaining healthy actuators, achieving early protection control, fault diagnosis, and fault-tolerant operation. This system is suitable for multi-zone centralized air conditioning scenarios and improves system operational safety and reliability.
