严寒地区高速公路服务站区地源热泵系统的运行模拟

严寒地区高速公路服务站区冬季供暖量大,夏季基本没有供冷需求,故单独使用地源热泵系统会造成浅层土壤温度场逐年下降,导致系统无法正常运行。太阳能作为一种清洁、廉价的能源,冬季可以和地源热泵系统联合运行供暖,其他季节可以为浅层土壤补充热量,以维持土壤温度场的平衡。以山西某高速公路服务站区为例,对其太阳能和地源热泵联合运行进行工况模拟,其分析和结论可为严寒地区高速公路服务站区地源热泵系统的长期正常服务提供重要技术支持。

The Running Simulation of Ground Source Heat Pump System for Highway Service Area in Severe Cold Area

For a highway service area in Shanxi as an example, this paper carried on the joint operating conditions simulation of its solar energy and ground source heat pump. Its analysis and conclusions could provide important technical support for the long-term normal service of highway service area ground source heat pump system in severe cold area.
