Although fuel-burning systems have long been used as climate control tools in greenhouses, their energy efficiency remains low, causing hikes in operation costs and sacrificing the quality and quantity of horticulture products, not to mention emitting greenhouse gases. To address these issues, a new geothermal energy supply model was developed for greenhouses close to highway Interchanges (ICs) or Junctions (JCTs). This paper presents a comprehensive effort made with field tests and simulations to validate the proposed model at various locations in South Korea. First, a Ground Source Heat Pump (GSHP) system – a central component of the model - was installed in a greenhouse and its efficiency was evaluated and compared with other fuel-burning systems. Second, cost-benefit analyses were carried out to assess whether the proposed model was investible under four possible operation scenarios. Third, the model was simulated at twenty-four ICs and JCTs along 9 highway routes to illustrate the beneficial effects of the model’s scaled-up deployment. The proposed model yielded the highest net income when a GSHP system was running at full capacity for heating and cooling. The payback periods of the model deployed at multiple sites (24 ICs and JCTs) were fewer than two years relative to AC/boiler systems. These findings indicate that the proposed model can be worthy of investment if it is appropriately operated and deployed in the field. Existing rules and policies could be used to help promote the implementation of the model.

尽管燃料燃烧系统长期以来被用作温室中的气候控制工具，但是它们的能量效率仍然很低，导致运营成本上升，并且牺牲了园艺产品的质量和数量，更不用说排放温室气体了。为了解决这些问题，针对靠近高速公路交汇处（IC）或交界处（JCT）的温室开发了一种新的地热能源供应模型。本文介绍了通过现场测试和模拟所做的全面努力，以验证在韩国各个地点提出的模型。首先，将地源热泵（GSHP）系统（该模型的主要组成部分）安装在温室中，并对其效率进行了评估，并与其他燃料燃烧系统进行了比较。第二，进行了成本效益分析，以评估所提出的模型在四种可能的运营情景下是否可投资。第三，在9条高速公路沿线的24个IC和JCT上对该模型进行了仿真，以说明该模型按比例扩大部署的有益效果。当GSHP系统满负荷运行供热和制冷时，提出的模型产生了最高的净收入。相对于AC /锅炉系统，在多个站点（24个IC和JCT）部署的模型的投资回收期不到两年。这些发现表明，如果在现场进行适当的操作和部署，建议的模型可以值得投资。现有规则和政策可用于帮助促进该模型的实施。在9条高速公路沿线的24个IC和JCT上对该模型进行了仿真，以说明该模型按比例放大部署的有益效果。当GSHP系统满负荷运行供热和制冷时，提出的模型产生了最高的净收入。相对于AC /锅炉系统，在多个站点（24个IC和JCT）部署的模型的投资回收期不到两年。这些发现表明，如果在现场进行适当的操作和部署，建议的模型可以值得投资。现有规则和政策可用于帮助促进该模型的实施。该模型在9条高速公路沿线的24个IC和JCT上进行了仿真，以说明该模型按比例放大部署的有益效果。当GSHP系统满负荷供热和制冷时，建议的模型产生了最高的净收入。相对于AC /锅炉系统，在多个站点（24个IC和JCT）部署的模型的投资回收期不到两年。这些发现表明，如果在现场进行适当的操作和部署，建议的模型可以值得投资。现有规则和政策可用于帮助促进模型的实施。当GSHP系统满负荷运行供热和制冷时，提出的模型产生了最高的净收入。相对于AC /锅炉系统，在多个站点（24个IC和JCT）部署的模型的投资回收期不到两年。这些发现表明，如果在现场进行适当的操作和部署，建议的模型可以值得投资。现有规则和政策可用于帮助促进模型的实施。当GSHP系统满负荷运行供热和制冷时，提出的模型产生了最高的净收入。相对于AC /锅炉系统，在多个站点（24个IC和JCT）部署的模型的投资回收期不到两年。这些发现表明，如果在现场进行适当的操作和部署，建议的模型可以值得投资。现有规则和政策可用于帮助促进该模型的实施。
