1. A method for estimating a temperature of an air stream at or proximate to an outlet, the method comprising:
determining a first heat transfer rate to or from the air stream based on a first temperature applied to the air stream;
determining a second heat transfer rate to or from the air stream based on a second temperature applied to the air stream by a conduit through which the air stream travels;
calculating a rate of change of the air stream temperature based on the first and second heat transfer rates and optionally one or more additional heat transfer rates; and
updating an estimated temperature of the air stream 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;
wherein the air stream is forced to the outlet by a blower and expelled from the outlet into a vehicle cabin, the first and second temperatures being applied to the air stream between the blower and the outlet.
