Solar/Performance Goals for Solar and Ground-Coupled Heat Pump Systems

摘要

Cost goals for combined solar/heat pump systems are developed. Three methods of analysis are used: simple payback, positive cash flow, and life cycle costing. The goals are parameterized on system energy efficiency, with the air-to-air heat pump as the conventional system which is used as a basis for comparison. Cost goals for nine systems are determined in three generic climates. (ERA citation 06:008904)
