System and Method for Controlling Operations of Air-Conditioning System

A system for controlling an air-conditioning system generating a flow of fluid in a conditioned environment, comprising:

• a set of sensors for measuring values of the flow in the conditioned environment;
• a memory storing a set of regimes of fluid dynamic in the conditioned environment and a corresponding set of models of flow dynamics connecting values of velocity and temperature of fluid conditioned during the operation of the system;
• and
• a controller for controlling the operation of the system based on a modeled flow, wherein the controller includes a processor for selecting a regime matching the measured values of the flow, for selecting a model corresponding to the selected regime, and for determining the modeled flow using the selected model.

An air-conditioning system, comprising:

• a user input interface for receiving a setpoint;
• a set of sensors for measuring values of airflow in the conditioned environment;
• an evaporator having a fan for adjusting an airflow rate through a heat exchanger;
• a condenser having a fan for adjusting the airflow rate through the heat exchanger;
• a compressor having a speed for compressing and pumping refrigerant through the system;
• an expansion valve for providing an adjustable pressure drop between a high-pressure portion and a low-pressure portion of the vapor compression system;
• a memory storing a set of regimes of fluid dynamic in the conditioned environment and a corresponding set of models of flow dynamics connecting values of velocity and temperature of the airflow conditioned during the operation of the system;
• and
• a controller for controlling the operation based on a modeled airflow to achieve the setpoint, wherein the controller includes a processor for selecting a regime matching the measured values of the airflow, for selecting a model corresponding to the selected regime, and for determining the modeled flow using the selected model.
