ABSTRACT:
A fabric drying system has an exterior housing and a rotating chamber for containing fabric laden with moisture that is to be dried and uses a combination of microwave energy and an auxiliary convection air heater to heat and vaporize the moisture and expel it with exhaust air so as to dry the fabric. In addition, the fabric drying system employs energy efficiency devices that permit the system to dry the fabric using the least amount of energy. Heat energy from the exhaust air is transferred to the intake in a heat exchanger. Additionally, heat energy from the exhaust air is used by recirculating a portion of the exhaust air and mixing it with the intake air before the air is introduced into the fabric drying chamber. The system also provides for sensors that detect the temperature and/or humidity of the exhaust and the intake air. A controller receives information from the sensors and develops a schedule of operation for controlling the energy sources and the energy efficiency features of the fabric drying system. The controller further monitors one or more sensors and uses the information to adjust the schedule of operations to provide for overall system efficiency.
