Residential zero net energy/low energy buildings require integrated renewable energy air conditioning systems especially in harsh climates such as Phoenix, AZ. In this paper, the thermal as well as economic performances for three types of residential-scale solar-powered heat pump systems is compared. The systems selected for this study were silica gel-water adsorption, single-effect LiBr-water absorption (both thermally driven), and solar photovoltaic (PV) powered vapor compression systems. An hourly building simulation model was developed for a single-family house in the Phoenix, Arizona, USA metropolitan area and performance of each of these systems was determined to satisfy the hourly cooling demand. The effect of solar collector area and storage capacity was also investigated.
