Definition of Exponential Function. An Exponential Function is a function of the form y = abx, where both a and b are greater than 0 and b is not equal to 1. Exponential Decay. Exponential decay occurs when a quantity decreases by the same proportion r in each time period t.
A vent damper is an automatic devise that shuts off the flue pipe when the burner is not running. A vent damper has no effect on the running efficiency of the appliance. It only saves off-cycle losses of heated air. Therefore, if the appliance is in an unheated space, there is no benefit to a vent damper. A vent damper can achieve up to 10% annual fuel savings.
Barometric!By,Pass!Dampers! The Static Pressure Regulating Dampers are barometric relief. dampers used to by-pass excess air pressure on zoned systems. The. dampers automatically respond to the air pressure in duct as the. various zone dampers open and close. As zone dampers close off air to a number of zones, the supply air. pressure in the duct system will increase. This increase in air pressure. can increase the noise level and reduce the flow of conditioned air. through the HVAC Unit. Using a by-pass damper solves this by.
