Assessment of Internal Combustion Engines as Drivers for Heat Pumps. Final Report

摘要

The present suitability and future potential of internal combustion engines as drivers for heat pumps was assessed for residential and light commercial machines up to 100 kW output (or approximately 50 HP input). This assessment included: a review of prior I.C. engine experience in similar applications; the determination of current engine characteristics important to heat pump systems; a conceptual design and evaluation of system economic potential and operational features; and recommended options for further development. The study showed that the internal combustion driven heat pump is technically feasible with current engine technology and that economic potential is promising for larger sizes. Developmental options recommended include: system demonstration, annual performance simulation, production cost projections and market analysis. (ERA citation 09:010072)
