Abstract The feasibility of installation and performance of vertical ground source heat pump (GSHP) systems for heating and cooling of a typical 9000 m2 office building located in ten metropolitan cities with tropical and subtropical climates are investigated. The heating and cooling loads of the identical building in the ten cities are simulated using the EnergyPlus software. For each location, the design of the GSHP system is performed using the ground loop design (GLD) software, and the performance of the GSHP system is assessed. A multi-year cost analysis is also carried out to assess the feasibility of installation of GSHP systems from an economic point of view. It is found that GSHP systems may not be economically viable for the cities in tropical climates, particularly those near the equator, because of inefficient performance and high cooling demand. Thermal imbalance in soil caused by significantly greater cooling demand than heating demand may further exacerbate the system in tropical cities. However, the implementation of GSHP may turn into a feasible option for some of the tropical cities located near the Tropic of Cancer by adopting special design techniques or including additional hybrid energy sources. GSHP systems seem to be economically feasible and operationally efficient in the cities with subtropical climates where more balance between heating and cooling loads exist.

地源热泵系统在热带和亚热带气候商业应用的可行性和性能

摘要 研究了立式地源热泵 (GSHP) 系统为位于热带和亚热带气候的 10 个大城市中的典型 9000 平方米办公楼供暖和制冷的安装和性能的可行性。使用 EnergyPlus 软件模拟十个城市中同一建筑物的热负荷和冷负荷。对于每个位置，地源热泵系统的设计都是使用接地回路设计 (GLD) 软件进行的，并评估地源热泵系统的性能。还进行了多年成本分析，以从经济角度评估安装地源热泵系统的可行性。研究发现，地源热泵系统对于热带气候的城市，尤其是赤道附近的城市，在经济上可能不可行，由于低效的性能和高冷却需求。由于制冷需求明显大于供暖需求而导致的土壤热失衡可能会进一步加剧热带城市的系统。然而，通过采用特殊的设计技术或包括额外的混合能源，地源热泵的实施可能会成为一些位于北回归线附近的热带城市的可行选择。地源热泵系统在具有亚热带气候的城市中似乎在经济上可行且运行效率高，在这些城市中，热负荷和冷负荷之间存在更多平衡。通过采用特殊的设计技术或包括额外的混合能源，地源热泵的实施可能会成为一些位于北回归线附近的热带城市的可行选择。地源热泵系统在具有亚热带气候的城市中似乎在经济上可行且运行效率高，在这些城市中，热负荷和冷负荷之间存在更多平衡。通过采用特殊的设计技术或包括额外的混合能源，地源热泵的实施可能会成为一些位于北回归线附近的热带城市的可行选择。地源热泵系统在具有亚热带气候的城市中似乎在经济上可行且运行效率高，在这些城市中，热负荷和冷负荷之间存在更多平衡。
