A microwave heating system for conditioning air in a space by heating the air to change its temperature

摘要

A microwave heating system is provided which heats air for a heated space in a heater. The heater includes two concentric enclosures which form an inner and an outer enclosure. The enclosures have an upper end and a lower end. A heating substrate is located in the inner enclosure. The heating substrate is mounted inside the enclosure. One magnetron for generating microwaves is mounted adjacent to the heating substrate in the outer enclosure. The magnetron is for directing microwaves into the heating substrate. An electrical distribution system is connected to the magnetron. Air is drawn from inside the heated space and is directed to the heater through an intake channel. The intake channel is in air communication with the inner enclosure and the outer enclosure. The air flows into the inner enclosure where the temperature of the air changes. The inner enclosure and the outer enclosure are in air communication with a return channel. The air then flows back to the heated space through a return channel. An air circulator is located within the return channel.
