阶梯气价与电价对居民用户能源费用的影响

Impact of Ladder Price for Natural Gas and Electricity on Energy Cost of Residential Users

从能源全生命周期角度得出天然气综合利用效率约为电力的2.5~4倍。通过试验数据,计算并对比烧开水、蒸饭、炒菜和生活热水设备的天然气与电力费用。通过调研,建立理想家庭能源费用模型,将实际家庭用能方式分为5类,计算3人/户和2.5人/户的居民用户年能源费用。在阶梯价格下,3人/户居民用户年能源费用是全用电力费用的0.506~0.918倍,2.5人/户居民用户年能源费用是全用电力费用的0.511~0.928倍。阶梯价格对居民用户年能源费用有影响。使用天然气的年费用低于使用电力的年费用。

It is calculated that the integrated u- tilization rate of natural gas is about 2.5 to 4 times of that of electricity as per the life circle. The natural gas and electricity costs for boiling water, steamed rice, stir- fry and domestic hot water are calculated and compared by experimental data. Through the investigation, the i- deal household energy consumption model is estab- lished, the actual household energy consumption pattern is divided into five classes, and the annual energy costs of 3 persons/household and 2.5 persons/household are calculated. Under the ladder price, the annual energy cost of 3 people/household is 0. 506 to 0. 918 times of the electricity cost, and the annual energy cost of 2.5 people/household is 0.511 to 0. 928 times of the elec- tricity cost. The ladder price has an impact on the an- nual energy cost of residential users. The annual cost of using natural gas is lower than the annual cost of u- sing electricity.
