HEAT EXCHANGER

摘要

A furnace or other heat exchanger application for heating, ventilation, air conditioning and refrigeration systems having condensate control. Specifically, a condensate control for secondary heat exchangers is provided for use with high efficiency furnaces, particularly for small tonnage systems, such as residential or unitary systems. Condensate management permits a plurality of furnace orientations while providing resistance to corrosion due to liquid condensate.

主权项

1. A furnace comprising:
a first heat exchanger; a second heat exchanger in fluid communication with the first heat exchanger; a first panel, the first panel being connected to the first heat exchanger and the second heat exchanger; a second panel positioned opposite the first panel, the second panel being connected to the first heat exchanger and the second heat exchanger; a first corrosion resistant body affixed to the first panel, the first corrosion resistant body being positioned near the second heat exchanger to prevent condensate from the second heat exchanger from contacting the first panel; a second corrosion resistant body affixed to the second panel, the second corrosion resistant body being positioned near the second heat exchanger to prevent condensate from the second heat exchanger from contacting the second panel; the first corrosion resistant body having a surface area less than the first panel and larger than an end of the second heat exchanger; and the second corrosion resistant body having a surface area less than the second panel and larger than an end of the second heat exchanger.
