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