摘    要:对国内多所高校浴室供热用能方式进行调研。调研结果显示近半数公共浴室仍然采用燃煤锅炉制备热水。天然气资源有限和运行成本高的问题限制了"煤改气"政策的实施。因此对某高校学生浴室提出采用空气源热泵制取热水,从而降低运行费用的方案。对该热泵系统运行时间、运行效率、能源消费、运行费用和投资回收期等指标的计算表明,在15年的运行周期中,空气源热泵热水供应系统在全年大部分时间内可以完全取代传统燃气锅炉供热。其运行费用比燃气锅炉系统节约47%,具有良好的节能效果和经济效益。

关 键 词:空气源热泵  能耗  运行费用  浴室

Abstract:According to a research of hot water system in bathroom for dozens of domestic universities and colleges,coal-fired hot water boilers are used in nearly half of these student bathrooms.Shortage of resources and high operating cost limit the use of natural gas.Therefore,an air-source heat pump system is recommended for heating water for the student bathroom in a college.The running time and efficiency of the units,energy consumption of the hot water supply system,operating cost and payback period of the heat pump system are calculated.In 15 years of the operation period,the air-source heat pump hot water supply system can completely replace the traditional gas boiler in most of the time in a year and reduce about 47% of operating cost.
Keywords:air-source heat pump  energy consumption  operating cost  bathroom
