Method for estimating outlet air temperature

Abstract

A method for estimating a temperature of an air stream. The method comprises determining a first and second heat transfer rate to or from the air stream, and optionally one or more additional heat transfer rates to or from the air stream. The first and second heat transfer rates are based on a first and second temperature, respectively, applied to the air stream. The rate of change of the air stream temperature is calculated based on the first and second heat transfer rates and optionally the one or more additional heat transfer rates. An estimated temperature of the air stream is updated from a prior program cycle based on the rate of change of the air stream temperature and the estimated air stream temperature from the prior program cycle.
