Seasonal heat pump performance for a typical northern United States environment
Abstract
An analysis of seasonal heat pump performance in a typical northern United States environment (approximately 8000 degree-days of heating) was performed for several typical commercially available air- and water-source heat pumps. Typical air-source and water-source heat pumps were selected from an Air-Conditioning and Refrigeration Institute publication, 'Directory of Certified Unitary Heat Pumps' (1976). Parametric seasonal performance analyses were performed for each heat pump. The results of these parametric studies showed that typical air-source heat pumps currently on the market will, when used in conjunction with electrical resistance auxiliary heating, save on the order of 45% of the energy required to heat a standard-sized home normally using electrical resistance heating alone. Typical water-source heat pumps operating from 60 F and 80 F water-source temperatures will save on the order of 64% and 67% respectively, of the heating energy over electrical resistance heating for a similar heating requirement. Pumping water from deep wells reduces these energy savings considerably.
