混合式地源热泵系统（HYGCHP）将传统地源热泵（GCHP）设备与辅助散热或抽汽系统耦合。在以制冷或供暖为主的气候条件下，使用这些辅助系统已被证明能显著提高系统的经济性和能源利用率。然而，HYGCHP的设计和运行远比GCHP复杂，目前执业工程师可获取的这方面的信息相对较少。 该项目通过开发一个详细的基于仿真的工具来解决这个问题，该工具结合了使用TRNSYS仿真程序的HyGCHP系统组件的基于物理的模型。仿真模型已被用于开发一个可分发的软件工具，供执业工程师使用，并完成对气候、建筑类型、经济和物理假设不同的许多不同场景的参数研究。参数研究的结果展示了一套通用设计指南，可用于选择设备配置、设备尺寸和控制典型HyGCHP系统的设备。 单位:I-P

Hybrid ground-coupled heat pump systems (HyGCHPs) couple conventional groundcoupled heat pump (GCHP) equipment with supplemental heat rejection or extraction systems. In cooling- or heating-dominated climates, the use of these supplemental systems has been shown to significantly improve the economics and energy usage of the system. However, the design and operation of HyGCHPs are significantly more complex than GCHPs and there is currently relatively little information available in this regard that is accessible to the practicing engineer.This project solves this problem through the development of a detailed simulation-based tool incorporating physics-based models of the HyGCHP system components using the TRNSYS simulation program. The simulation model has been used to develop a distributable software tool for use by the practicing engineer, as well as to complete a parametric study of many different scenarios varying in climate, building type, and economic and physical assumptions. The results of the parametric studies demonstrate a set of general design guidelines that can be used to select an equipment configuration, size equipment, and control the equipment of a typical HyGCHP system.Units: I-P
