Title: Extension of Phoenix/City of Colorado Springs solar assisted heat pump project. Final report

Ground coupled heat pump systems employing commercially available equipment have been installed and tested in three different climatic regions of the US in residential, commercial, and industrial building applications. These systems were automatically controlled to respond to load requirements and provided space heating, space cooling, and domestic water heating. Results of the key technical and economic tradeoff work are presented. Component and configuration options are screened and a final cost effective design is justified. Final system design specifications are given. A complete preliminary design of a natural gas fired heat pump is reported, including a performance analysis. The market side economics of the system is examined, including load and system performance, system and utility energy cost summaries, and an economic analysis for new and retrofit systems. The impact of electric and gas utility interfaces with the system is discussed. The status of the natural gas and electric power utilities systems in the Colorado Springs area are assessed. Some options for commercializing the system are discussed. (LEW)
