- 该图书馆需安装空调面积总计100平方米左右，图书馆无发热设备，且对温湿控制及节能有要求。依据实际情况每平米所需制冷量平均按350W计算，总需求的35KW制冷量。
The total area is of about 100 square meters for the library, and there is no heating source, and it requires the temperature and humidity control and energy saving features. Required cooling capacity per square meter on average calculated based on the actual situation according to 350W, the total demand for cooling capacity is of 35KW.
- 精密空调要满足该项目35KW的制冷量，需使用HIMOD M41机组1套装机。
To meet the cooling capacity of 35KW, this project is needed to use one set of unit (HIMOD M41).
- 经济效益对比估算：传统空调满足35KW制冷量的输入功率至少为12KW左右，而HIMOD M41机组1套主机的输入功率合计为7.4KW，主机部分省电38.3%，全年共计节省电费0.9万元以上。(按1年运行8个月，1月运行30天，1天运行8小时，用电按1元1度计算)
Comparison of economic benefit estimation: the traditional air-conditioning input power (35KW cooling capacity) is at least about 12KW, and the HIMOD M41 input power per set is of 7.4KW. The energy saving is up to 38.3%. The annual saving is more than 9000 CNY. (According to 8 months per year, 30 days per month, 8 hours per day of operation, electricity by 1 CNY/1 degree calculation)
