1、Rule of Thumb & Schindler Benchmark.基本原则和迅达基准Introduction & Guidelines.相关介绍和指引,.2,Rule of Thumb.基本原则A Methodic of best guess of the Elevator Configuration needed.对电梯配置进行有条理和最有效预估的要素,.3,Rule of Thumb. 基本原则How to Design an Elevator for an Office Building?如何规划办公楼的电梯配置?,Defined Building Population ? 确定大
2、楼人数? Defined HC5 Requirement ? 确定5分钟运载能力要求? Defined WT Requirement ? 确定候梯时间要求? Define Number of Elevators 确定电梯数量 Define Car Speed 确定电梯速度 Define Car Load 确定电梯载重,.4,Rule of Thumb. 基本原则Estimate Numbers of Elevators needed. 估算电梯数量, 250 persons per elevator 每台电梯服务250人, 4 - 5 floors per elevator 每台电梯服务4-5
3、个楼层, 24 floors per elevator group 每个梯组服务24个楼层,.5,Office Building. 办公楼Define the Car Speed. 确定电梯速度,HQ = Travel height (65m example beside)HQ = 提升高度(假设左侧例子的提升高度为65米)T = Travel time from main floor to top floor without taking time losses into account caused by acceleration and decelerationT = 从基站直驶到最高层
4、站的时间,不考虑加减速等 额外时间Recommended Values for Travel Time行程时间推荐值- 20 sec for top requirement (example beside) 顶级标准为20秒(假设左侧例子如是)- 25 sec for medium requirement 中档标准为25秒 - 32 sec basic requirement 普通标准为32秒VKN = HQ / T = 65m / 20s = 3.25 m/s,.6,Rule of Thumb. 基本原则Summary. 综述,.7,Rule of Thumb. 基本原则Relation W
5、T / INT. WT和INT的关系,Interpretation of Interval Waiting Time说明:间隔时间候梯时间The relation of interval INT and average waiting time WT has been examined for a number of different elevator groups. It has found out that the ratio WT/INT depends very much on the elevator group and on the arrival rate (as percen
6、tage of the maximum handling capacity).经过对比不同梯组的电梯间隔时间和平均候梯时间,我们发现:WT/INT系数很大程度上取决于梯组配置和到达率(与5分钟运载能力最大值相等)For assessing an elevator groups maximum performance, the usual relation of “WT = 60 % x INT” is not realistic. Better use “WT = 80 % x INT” or even “WT = INT”.要对电梯梯组的最大性能进行评估,惯常用的“WT=60%xINT”公式
7、并不能反映真实情况,建议使用“WT=80%xINT”或“WT=INT”。,.8,Rule of Thumb. 基本原则How to Define the Car Load GQ? 确定电梯载重,P = Ar x INTP = Passengers per car (car loaded with 80%)P = 每个轿厢的乘客数量(轿厢满载率80%)Ar = Arrival rate = arriving persons per secondAr = 到达率 = 每秒内到达的人数INT = Interval considering waiting time WT = 80% of INT =
8、rough estimationINT = 间隔时间按WT=80%xINT考虑 = 粗略估算Arrival Rate Ar (example): 到达率Ar(举例说明):Population = 800, handling capacity = 14 %, arriving persons = 112 persons / 5 min人数=800,运载能力=14%,到达人数112人/5分钟Ar= 0.3733 persons / sec. Ar=0.37733人/秒Interval INT (example): 间隔时间INT(举例说明):Required waiting time WT = 2
9、4 sec 候梯时间要求WT=24秒Interval = (WT/80)x100 = 30 sec间隔时间 = (WT/80)x100 = 30秒Car Load 电梯载重P = Ar x INT = 0.3733 persons/sec x 30 sec. P = Ar x INT = 0.3733人/秒 x 30秒= 11.2 persons considering 80% car load = 11.2人,80%轿厢满载率= 14.0 persons considering 100% car load = 14.0人,100%轿厢满载率GQ 100% = 14 persons x 75
10、kg / person = 1050 kg = choose 1250Kg,.9,Traffic Vision 3.0Overview 概览,Given Input 假设值:Building with a Population of 800 大楼总人数800人Amount of floors above main Floor = 16 基站以上楼层数=16Travel Height around 65 m 提升高度大约为65米Required HC 5 = 14% 要求HC5=14%Required average WT around 24 sec 要求平均候梯时间WT约为24秒1.Estim
11、ated Number of Elevators 估算电梯数量Number of Elevators = 4 (800People / 200People per Elevator) and (Floor amount / 4floor serving per Elevator) = Higher value should be considered电梯数量=4(800人/每台电梯服务200人),如同时使用另外一个公式(楼层数/每台电梯服务4个楼层)来计算电梯数量,应取两者的最大值。2.Estimated Speed 估算电梯速度Elevator Speed to reach top/medi
12、um level travel time between 20-25 secV = HQ/t=20sec = 65/20 = 3.25 m/s expected speed 3m/s如要满足顶级或中档要求,电梯的行程时间应在20-25秒之间V=HQ/t=20秒=65/20=3.25米/秒,预期电梯速度为3米/秒。3.Estimated Car load 估算电梯载重INT = (WT/80) x 100 = (24/80)x100 = 30 secAr = (Population/100)*HC5 / 300 = (800/100)*14/300 = 0.37333 Persons/secP
13、= Ar * INT = 0.3733 * 30 = 11.2 Persons (80% car load) 100% carload would be around 14.0 Persons) estimated car load (75 Kg/ person) = 1050 Kg would fit with a 1250 Kg Car Load DesignP=Ar*INT=0.3733*30=11.2人(轿厢满载率80%),如按100%轿厢满载率,人数约为14人,按75公斤/人,则电梯载重=1050公斤,向上取整得电梯载重1250公斤。,.10,Schindler Traffic St

15、点提示:As a Schindler guideline always follow the following rules.迅达指引总是遵循以下原则:Look at the lowest rating of all analyses of a project. Then:查看项目里所有的分析数据,找出最低值,然后:3 stars or more are o.k. and recommended.如果达到三星级或以上,该电梯配置可行并可推荐。2 stars: Such projects must be examined carefully (including a second opinion
16、 e.g. of a superior) and are only accepted for good reasons. You should be aware that such a project is marginal w.r.t. elevator performance, and we might face critical questions or problems related to high waiting times etc.二星级:这类项目必须仔细核实(如获取上级意见),如无充分理由将不予采纳。应当谨记这样的电梯配置其效能是相当低的,日后我们很可能会由于候梯时间等问题受到
17、客户的质询。1 star or less: Such projects must be rejected by Schindler. The elevator performance is poor, and such installations may cause severe problems and damage Schindlers reputation.一星级或以下:迅达必须拒绝承接这类项目。由于电梯的效能极差,在投入使用后会问题不断,直接影响迅达的声誉。,.14,Overview Report (Example)报告概览(例子)Illustration of an analysis
