摘要
以北京市某农艺园地热温室供热系统为例,分析了目前中低温地热能利用普遍存在的利用温差小、效率低等问题,并针对系统存在的问题提出了相应的改造方案以及系统节能改造后的节能分析。系统通过结合热泵机组梯级综合利用地热能的改造后,供热系统不仅可以实现节能运行,并且降低了尾水温度,提高地热水资源利用率。
Base on a greenhouse heating system in a Beijing＇s agricultural sightseeing garden, this paper analyzes the problems of small temperature difference and low efficiency in low temperature geothermal energy utilization, then presents some measures to saving those problems. In the end of this paper, the author analysis the energy savings. By taking the measures of combined with the heat pump units cascade and comprehensive utilization of geothermal energy, this heating system not only achieves the energy-saving operation, but also reduces the tail water‘s temperature and raises the utilization ratio of geothermal water resources.
