Abstract
Official abstract text for this publication.
A furnace includes an induced draft blower; an inducer motor driving the induced draft blower; and a furnace control determining a modulation percentage, the furnace control controlling RPM of the inducer motor in response to the modulation percentage.
First claim
Opening claim text (preview).
The invention claimed is: 1. The A furnace comprising: an induced draft blower; an inducer motor driving the induced draft blower; and a furnace control determining a modulation percentage, the furnace control controlling RPM of the inducer motor in response to the modulation percentage; wherein in a first range, the furnace control controls the inducer motor RPM based on the equation: inducer motor RPM=RPM 1 ×MODULATION %/K 1 where RPM 1 is a value derived from a…
