具体实施方式 Detailed ways

[0060] 节电量(率)的测量不是一个瞬态的过程,是一个较长时间段的过程,改造前后各需要10〜20天。 Section [0060] power (rate) measurement is not a transient process, the process is a long period of time, each needs 10-20 days before and after reconstruction. 其测量结果与上述6大因素都有很强的相关性。 The measurement results of the six major factors have a strong correlation. 所以在测量方法的设计上,必须利用统计学原理,对我们无法控制的因素(包括:室内热负荷,环境温度与湿度,供电电压波动等,这些属于统计学上的偶然误差),予以平衡和抵消。 Therefore, the design method of measurement must be using statistical theory, we can not control factors (including: an indoor heat load, ambient temperature and humidity, supply voltage fluctuations, these are statistically random error), and to be balanced offset. 同时通过改造前测试来揭示系统误差(包括:空调自身的因素,室内的气流组织带来的误差)并定义好修正的方式。 At the same time to reveal the systematic error (including: air conditioning own factors, indoor air distribution of the error caused) by the transformation of the former definition of a good test and revise the way. 这样才能得出比较客观精确得结果。 So as to arrive at a more accurate and objective results obtained.

E a = al+a2...+an ; E b = bl+b2...+bn。 E a = al + a2 ... + an; E b = bl + b2 ... + bn. 系统误差C =Ea/E b。 The system error C = Ea / E b. 对A 台(组)进行改造而B台(组)不改。 A station for (group) and B transformation stage (s) does not change. 将改造过的A空调开一天,获得电量Al,未改的B开一天,获得电量BI,如此数次,轮流交替运行,获得A2…An和B2…Bn. EA = A1+A2…+An ;EB = B1+B2...+Bn。 A transformation of the air conditioner will open one day, to obtain power Al, B unmodified open one day, to obtain the BI power, so several times, alternating between running, A2 ... An obtained and B2 ... Bn EA = A1 + A2 ... + An.; EB = B1 + B2 ... + Bn. 改造后误差D =EA/ EB。 After reconstruction error D = EA / EB. 节能率n = (CD)*100%。 Energy ratio n = (CD) * 100%.

[0088] 数据分析和结果计算: [0088] Data Analysis and Results Calculation:

[0089] 先求出改造以前的双机差异,以该差异为基础数据,在改造后,再重新计算两台空调的差异,这样的话,改造之前的双机能耗差别和改造之后的双机能耗差别之间的差异,即可视为由于空调改造所带来的效率变化(节能量),公式为: [0089] first find the differences before the dual transformation to the difference of the underlying data, after the transformation, and re-calculate the difference of two air-conditioning, so, after the dual dual-energy differences and renovation before renovation the difference between the energy difference may be regarded as changes in efficiency (energy savings) due to the transformation brought about by the air conditioning, the formula is:

[0090]改造前=A 机/B 机*100% ; [0091]改造后=A 机/B 机*100 ; [0092] 节能率=改造前-改造后。 [0090] Before the transformation unit = A / B * 100% machine; the [0091] transformation unit = A / B * 100 machine; before [0092] the transformation of the energy saving rate = - after transformation. [0093] 以上的公式导入原始数据我们可以得到节能量为: [0093] The above equation we can get the original data import section energy:

[0094]改造前:821. 2/602. 8*100%= 136. 23% ; . [0094] Before the transformation: 2/602 821 8 * 100% = 136.23%;

[0095]改造后:3294. 6/2871. 4*100%= 114. 73 ; . [0095] After the transformation: 6/2871 4 3294 * 100% = 114.73;

[0096]节能率=136. 23% -114. 73 = 21. 5%。 [0096] saving rate = 136.23% -114. 73 = 21.5%.
