摘要
通过对上海地区某酒店的冷热源配置和热回收方式的研究,对常规系统、部分冷凝热回收系统和全部冷凝热回收系统从经济性、节能性及碳排放三方面进行了比较分析。结果显示,采用部分冷凝热回收和全部冷凝热回收技术增加的初投资差异不大,分别为26.4万元和26.8万元,但每个供冷期节省的运行费用分别达60.4万元和74.1万元,且具有明显的节能减排效果,比常规空调系统分别减少碳排放量10%和9.2%。在单位环境成本不显著提高的前提下,全部冷凝热回收方式相对于其他空调模式在华东地区应用具有较高的经济、节能及环保性。
Discusses both the configuration of cold and heat sources and the heat recovery mode of a hotel in Shanghai. Compares and analyses the conventional system, part-load condensation heat recovery （PCHR） system and all-load condensation heat recovery （ACHR） system by economic and energy conservation analysis as well as carbon emission potential. The results show that the increase of initial investment of PCHR system and ACHR system than conventional system makes small difference, which is 264 000 yuan and 268 000 yuan respectively, but they can separately save operating costs of 604 000 yuan and 741 000 yuan for each cooling period. They have a significant energy saving effect which can reduce carbon emissions separately by 10% and 9.2%. Therefore under the premise of no significant increase of the unit environmental cost, ACHR mode has better performance of economy, energy saving and environmental protection in east China.
