Fundamentals of Venting and Ventilation

is the pressure difference found between the inside of the vent and the atmosphere around it. The combustion air entering the furnace is at atmospheric pressure which, at sea level, is about 14.7 PSIA (Pounds to the Square Inch Absolute pressure). The hot flue-gases rising out of the furnace are less dense, creating a pressure drop within

expansion tank absorbs any thermal expansion of the fluid. Open systems don’t require expansion tanks, as the fluid is naturally free to undergo thermal expansion. Figure 1: Closed and Open Hydronic Systems What is Pump Head? Units of Measure: In the U.S. system, head is measured either in PSI or in "feet of head" (usually abbreviated to "feet").

to the ozone layer. In fact, it is the re-frigerant by which the GWP of other refrigerants are measured. So, in terms of GWP, one pound of R-404A emis-sions is the equivalent of 3,922 lbs of CO 2 emissions. A variety of lower-GWP alterna-tives exist across the full spectrum of GWP ratings, but CO 2 is often con-sidered to be a refrigerant of ...
