ABSTRACT:
An apparatus and process for frost control for the ambient air heat exchanger of a space conditioning apparatus. The ambient air heat exchanger is immersed in a fluidized bed enhancing the heat transfer and physically reducing frost formation. In a preferred embodiment, the fluidized bed is supported by a support bed of non-fluidized solid particles. In one of the embodiments the particulate beds may be desiccant materials. The space conditioning apparatus and method of frost control of this invention permits smaller ambient air heat exchangers and accommodates greater transient conditions due to the enhanced heat transfer and physical prevention of ice formation resulting from the fluidized bed.
