河北省某医院供热与空调系统的节能改造研究浅析

A Brief Analysis of the Energy-Saving Renovation of the Heating and Air-Conditioning System of a Hospital in Hebei Province

摘要: 河北省公共机构的供热和空调系统能耗较大，需要进行整体优化以减少能耗。本研究针对河北省某医院的供热和空调系统进行了深入分析和评估，探讨了潜在的节能和效率改进措施。分析结果表明，热源设备选型过大，建议加装气候补偿装置；供热和空调系统的循环水泵需要加装变频控制系统以降低能耗；替换传统热源为土壤源热泵能够显著提高系统的能效和降低运行成本。此外，生活热水辅热系统也可以采用空气源热泵以实现节能。综合各项改造措施后，可显著提高医院的能源效率，减少二氧化碳排放。

Abstract: Heating and air-conditioning systems in public institutions in Hebei Province consume large amounts of energy and need to be optimized as a whole to reduce energy consumption. This study provides an in-depth analysis and assessment of the heating and air-conditioning system of a hospital in Hebei Province and explores potential energy-saving and efficiency improvement measures. The results of the analysis indicate that the heat source equipment is oversized and it is recommended that a climate compensation device be added; the circulating water pumps of the heating and air conditioning system need to be retrofitted with a variable frequency control system to reduce energy consumption; and the replacement of the traditional heat source with a soil source heat pump can significantly improve the energy efficiency of the system and reduce the operating costs. In addition, the domestic hot water auxiliary heating system can also use air-source heat pumps to achieve energy savings. The combination of all the retrofit measures can significantly improve the energy efficiency of the hospital and reduce carbon dioxide emissions.
