MODEL BASED SYSTEM AND METHOD FOR ESTIMATING PARAMETERS AND STATES IN TEMPERATURE CONTROLLED SPACES

摘要

A method (20) for estimating a heating/cooling load of a zone within a building (10) may include determining a measured parameter from the zone (22), generating a reduced order thermodynamic model (25) of the zone (24), generating an Extended Kalman Filter (27) based on the thermodynamic model (25) of the zone (26), and processing the measured parameter using the Extended Kalman Filter (27) to estimate at least one unknown state of the zone, such as an estimated load (28). A similar method may be used to estimate a temperature in a cold room (52) of a refrigeration system (50).
