摘要
为了弥补地源热泵在工程实例应用中存在只能工频运行,负荷调节范围很小这一不足,以济南市某办公楼为例,将一次变频循环泵应用于地源热泵中,通过在不同状况下,分析比较其初投资及运行费用与工频的不同,并得出应用变频循环泵后与普通循环泵相比,具有节能的效果,计算其回收期大约为5个月。
Ground source heat pump exists the phenomenon that it can only run with the power frequency and the range of load regulation is small in the engineering examples, in order to make up this deficiency, using a office building in Ji＇ nan as an example, we use a frequency conversion circulation pump in ground source heat pump, analyse its initial investment and operating cost compared with the power frequency in different conditions, and draw the conclusion that the frequency conversion pump can save energy compared with the general circulation pump, its payback period is about five months.
