Well-Water-Source Heat Pump Field Performance Study

摘要

The objective of this study is to obtain and analyze data pertaining to the field performance characteristics of two well-water-source heat pumps (WWSHPs) which are installed in two residences located in rural south-central Pennsylvania. These were existing single-family residences which were retrofitted with the WWSHPs. The heat pumps will supply heating in the winter and cooling during the summer. The heat pump installations are being instrumented with an automated data gathering system which will allow the performance of the systems to be evaluated. The first major aim of this project is to evaluate the data obtained so that seasonal performance factors and energy consumption characteristics of the WWSHPs may be evaluated. The second major aim of this project is to develop a mathematical model that simulates the actual performance satisfactorily and then to use this model to compare WWSHPs with other heating and cooling systems. Results to date have been the design of the instrumentation and data acquisition system and obtaining a preliminary design of the control logic and data reduction software for the minicomputer to be located at the sites.
