本文探讨我国京津市区丰富的低温地热资源有效利用的方法。文中着重分析有热泵参与的各种地热采暖系统的负荷分配和节能效果,论证热泵系统是提高低温能源利用率和城市采暖的有效方式。本文还介绍了地热热泵模拟试验和所得到的某些结果。在经济性分析中指出我国电和燃料比价与国外有很大不同,所以电动热泵直接经济效果还不明显。提议城市地区可用燃气机拖动热泵,并建议要有合理的能源政策促进热泵节能技术的发展。
This paper discusses the methods for the effective utilization of abundant low-temperature geothermal resources in Beijing and Tianjin. This paper focuses on analyzing the load distribution and energy-saving effects of various geothermal heating systems with heat pump participation, and demonstrates that the heat pump system is an effective way to improve low-temperature energy utilization and urban heating. This article also introduced geothermal heat pump simulation tests and some of the results obtained. In the economic analysis, it is pointed out that China’s electricity and fuel prices are very different from those of foreign countries, so the direct economic effect of electric heat pumps is not obvious. It is proposed that gas engines can be used to drive heat pumps in urban areas, and it is recommended that there be reasonable energy policies to promote the development of heat pump energy-saving technologies.
