基于动态费用年值法的空气源热泵加热系统能耗评价研究

Energy Consumption Evaluation of Heating System with Air Source Heat Pump Based on Dynamic Annual Cost

以志丹采油厂某井原油加热为例,采用动态年值法,从费用年值、等价标煤量、COP值、CO_(2)减排量4个方面对空气源热泵加热系统进行综合能耗分析,并与目前常用的锅炉加热、电磁加热、地源热泵、太阳能电辅等5种加热系统就上述4个方面进行能耗对比。结果表明,空气源热泵能耗的综合效益最好,可以作为未来加热系统的发展方向。

Taking the crude oil heating of a well in Zhidan Oil Production Plant as an example,the comprehensive energy consumption of the air source heat pump heating system is analyzed by using the dynamic annual cost from the four aspects of annual cost,equivalent standard coal,COP value and CO_(2) emission reduction,and the energy consumption of the heating system is compared with that of the five heating systems commonly used at present,such as boiler heating,electromagnetic heating,ground source heat pump heating and solar energy electric auxiliary heating.The results show that the comprehensive benefit of energy consumption of air source heat pump is the best,which can be used as the development direction of heating system in the future.
