For aggregate systems it is defined as the ratio of the sum of the individual non-coincident maximum loads of various subdivisions of the system to the maximum demand of the complete system. $f\_\; =\; \backslash frac(\backslash text\_i)\}\_i\}$ The diversity factor is almost always less than 1 since all components would have to be on simultaneously at full load for it to be one. The aggregate load $\backslash left(\; \backslash sum\backslash limits\_^n\backslash text\_i\; \backslash right)$ is time dependent as well as being dependent upon equipment characteristics. The diversity factor recognizes that the whole load does not equal the sum of its parts due to this time interdependence (i.e. diverseness). For example, we might have ten air conditioning units that are 20 tons each at a facility. In Florida we typically assume that the average full load equivalent operating hours for the units are 2000 hours per year. However, since the units are each thermostatically controlled, we do not know exactly when each unit turns on. If the ten units are substantially bigger than the facility's actual peak A/C load, then fewer than all ten units will likely come on at once. Thus, even though each unit runs a total of 2000 hours a year, they do not all come on at the same time to affect the facility's peak load. The diversity factor gives us a correction factor to use, which results in a lower total kW load for the ten A/C units. If the energy balance we do for this facility comes out within reason, but the demand balance shows far too many kW for the peak load, then we can use the diversity factor to bring the kW into line with the facility's true peak load. The diversity factor does not affect the kWh; it only affects the kW. == Coincidence factor == The coincidence factor is the reciprocal of the diversity factor. However, differing sources define the simultaneity factor to be identical to either the coincidence factor or the diversity factor. The International Electrotechnical Commission defines the coincidence and simultaneity factors identically with the diversity factor being the reciprocal. Since the only change in definition is to take the inverse, all one needs to know is if the factor is greater than or less than one. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Diversity factor」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
