Performance of a residential size solar augmented heat pump is reported for the 1980 to 1981 heating season. The facility (UTK Solar House II) located in Knoxville, Tennessee, has a measured heat load coefficient of 357 watt//sup 0/C (677 Btu/hr- F). The solar augmented heat pump system consists of 29.4m/sup 2/ (316.8 ft/sup 2/) of flat plate, air heating type collectors and 7.4m/sup 3/ (260 ft/sup 3/) of one inch diameter crushed limestone. The heat pump is a nominal 8.8 kW (2 1/2 ton) high efficiency unit. Hourly thermal performance and on-site weather data are reported for the period October 13, 1980 through February 28, 1981. Thermal performance data consist of heat flow summations for all modes of the system, pebble bed temperatures and space temperature. Weather data consists of dry bulb temperature, dew point temperature, total global insolation (in the plane of the collector) and wind speed and direction. Of a possible 3336 hours, 3087 hours of data were taken (93%). Solar system thermal performance factor was measured to be 9.31 for the reporting period. Thermal performance factor of 1.63 was measured for the heat pump. Total system seasonal performance factor was measured to be 2.55.
