摘要
既有建筑物经历长期运行,冷热源设备能耗及运行费用高,室内环境有待改善。燃气直燃机系统采用燃气制冷制热,运行成本受燃气费用波动影响较大。采用热源塔热泵改造直燃机系统,既可同时供冷供热,系统能效也得到较大的提升。介绍了热源塔热泵技术原理,原项目能源站能耗及能源站采用热源塔热泵改造的技术方案和技术经济比较。
Both buildings will have a high heat and cold source equipment energy consumption and operation cost after a long run, which need to be improved of the indoor environment. Gas direct-fired machine adopts gas for refrigeration and heating. And its running cost are greatly influenced by gas cost fluctuation. The retrofit heat pump heat source tower direct-fired machine system can both produce cooling and heating at the same time, and the system energy efficiency is also improved. The paper introduces the heat source heat pump technology principle, the original project energy station energy consumption and an energy retrofit standing tower heat sources of technical scheme and technical and economic comparison.
