Definitions for "Load Duration Curve"
A graph made by plotting data in order of magnitude against time intervals for a specified period. The ordinate may be an absolute quantity or percentage.
A nonchronological, graph summary of demand levels with corresponding time durations using a curve, which plots demand magnitude (power) on one axis and percent of time that the magnitude occurs on the other axis.
The 1 in 50, or severe, load duration curve is that curve which, in a long series of years, with connected load held at the levels appropriate to the year in question, would be such that the volume of demand above any given demand threshold (represented by the area under the curve and above the threshold) would be exceeded in one out of fifty years.
a graphic model which can be extremely helpful in designing and sizing a chilled water system
