Abstract:
1. A method of operating a clothes dryer comprising a rotating drum defining a clothes drying chamber, an air flow system for supplying air to the clothes drying chamber and exhausting air from the clothes drying chamber, a motorized blower for moving air from an inlet to the drying chamber, through the clothes drying chamber, and through an exhaust inlet, and a heater for heating the air, the method comprising: supplying air through the air flow system to define a supply air flow; determining at least one parameter of the supply air flow; calculating from the at least one parameter a supply air flow value indicative of a volumetric flow rate of air supplied to the clothes drying chamber; calculating an exhaust air flow value indicative of a volumetric flow rate of air exhausted from the clothes drying chamber; and determining a volumetric flow rate of the air flow through the air flow system based on the supply air flow value and the exhaust air flow value.
