热泵蓄热供暖系统经济性的分析

Economic analysis of heat pump regenerative heating system

针对目前燃煤锅炉供暖污染大,燃气锅炉、电锅炉供暖能耗高、费用高,日间高峰时段供气、供电紧张等问题,提出一种热泵蓄热供暖系统。以北京市某办公楼为例,利用Python软件建立运算程序,分析了该系统中蓄热装置与热泵的选型及初投资和后期运行费用。研究结果表明:该热泵蓄热供暖可以明显降低办公建筑供暖设备运行成本,平峰填谷,有效缓解电网高峰供电压力。

In view of the current serious pollution of coal-fired boiler heating, high energy consumption and high cost of heating by gas-fired boilers and electric boilers, and shortage of gas and power supply during peak hours during the day, a heat pump heat storage heating system is proposed. Taking an office building in Beijing as an example, using Python software to establish a calculation program, the selection of heat storage devices and heat pumps in the system and the initial investment and later operating costs are analyzed. The research results show that the heat pump heat storage heating can significantly reduce the operating cost of heating equipment in office buildings, level the peaks and fill the valleys, and effectively alleviate the peak power supply pressure of the power grid.
