Maximum loads and annual running time inputs are automatically calculated in the GeoXergy PlugIn in the appropriate worksheet. Simply copy the four values in the GeoXergy PlugIn and then click the excel button to paste the values into GLD.
GeoXergy插件在对应的工作表中自动计算出最大负荷和年运行时间投入。在GeoXergy插件中简单复制四个值,然后单击“Excel“按钮,将它们粘贴到GLD软件中。

For designers using other loads calculations programs/methodologies 设计师使用其他负荷计算软件/算法::

GLD needs the peak hourly heating and cooling loads for the installation. GLD also needs the annual running time (in a percentage format where 0% means the system is not running at all during the year and where 100% means the system is running at peak load 100% of the year).
GLD需要得到安装所需的峰值小时冷热负荷,以及每年运行时间(0%表示系统整年都没有运行,100%是指系统整年都以峰值负荷运行)。

There is more than one way to calculate the annual running time:
有多种方法可计算出年度运行时间:

A. Sum the total cooling loads for the year. Divide the sum by the peak hourly cooling load to get a result with units in "hours." Divide the result by the number of hours in a year (8760). The resulting percentage is the annual running time.
A:年度总的冷负荷除以峰值小时冷负荷,得到一个以”小时”为单位的结果,该结果除以一年总的小时数(8760),得到的百分比即年度运行时间。

Example:

Total annual cooling kBtus: 18500 kBtu

peak: 22 kBtu/hour

18500 kBtu/ 22 kBtu/hour =841 hours

841 hours/8760 hours/year = 9.6% annual running time.

Repeat for heating loads

例如:
年度总冷负荷:18500 kBtu
峰值冷负荷:22 kBtu/小时
18500 kBtu/22 kBtu/小时=841小时
841 hours/8760小时/年=9.6%的年度运行时间。
热负荷的计算与冷负荷类似。

B. For cooling, if the system were running at peak capacity, how many hours would it have to run for in order to take care of the cooling loads for the entire year? After determining the answer, divide it by 8760 to get the annual running time percentage.
B:在制冷模式,如果系统按峰值容量运行,需要多少小时才能满足全年冷负荷的需求?计算出的结果除以8760,即得到年度运行时间的百分比。

Repeat for heating loads.
热负荷的计算与冷负荷类似。
