Filed:
Nov 15, 2007
Appl. No.:
11/940682
Inventors:

Abstract:
A blower urges an airflow, at a rate according to a user-controlled flow rate command, through an electric heater and the electrical heater heats the airflow at a heater power based on a user-input temperature command, the user-input flow rate command, and a measured mass flow rate of the airflow. The heater power is calculated based on the heat energy required to heat air to the given reference temperature, at a flow rate corresponding to the measured mass flow rate. Optionally, the temperature of the air entering the electric heater is measured, and the heater power is calculated based on the heat energy required to heat air from the measured temperature to the given reference temperature, at a flow rate corresponding to the measured mass flow rate.
