ABSTRACT:
A recuperator structure for recovering heat values from a moisture laden hot gas stream and for utilizing these heat values to heat a space such as a room in which the structure comprises first, second, third, fourth, fifth and sixth ducts with the first, second and third ducts being used for conveying air from ambient to the space and having located therein heat exchangers and the fourth, fifth and sixth ducts communicating with the same heat exchangers for conveying a hot moist gas therethrough for heat exchange with the ambient air and then exhausting to the ambient, the result being that the hot moist gas gives up its heat values in the heat exchangers to the ambient air which is then exhausted in the resulting heated condition into the room. The disclosure also includes improved defrost means for the heat exchangers immediately contacted by the ambient air for removing frost that may be deposited thereon where the heat exchanger portions that are contacted by the hot moist gas are at subfreezing temperatures.
