FEASIBILITY OF COMBINED SOLAR/HEAT PUMP SYSTEMS FOR REDUCED RESIDENTIAL CONDITIONING ENERGY CONSUMPTION
Greg Marsicek, Sanford Klein, Greg Nellis
This paper investigates the impact of using an air- source heat pump system in a thermally efficient house for two locations: Chicago, IL and Dallas, TX. In addition to an air-source heat pump, a geothermal heat pump system is implemented in the Chicago location. The source energy savings over a conventional system is reported as well as the life cycle costs for each of these cases. The conventional system is a natural gas furnace and air conditioner. In addition, to improve the performance of the air-source heat pump system, photovoltaics and solar thermal systems are implemented to analyze the effects on the energy savings and life cycle costs.
