OSTI ID:6666120
The performance of the New Mexico State University Solar House, the Collins' Casa del Sol during the winter of 1978-1979 and the summer of 1979 is described. The performance is summarized in terms of daily, monthly, seasonal and yearly performance. During the heating season, the solar system met essentially all of the space heating load; the auxiliary boiler operated for only one half hour during the winter. The system supplied 70.8% of the heat for the domestic water during the winter season and 73.6% of the summer season domestic water heat. Solar energy supplied 26% of the energy needed to meet the cooling load with an average chiller C.O.P. of 0.5. The overall system C.O.P. was 4.29 for the winter season and 0.61 for the summer season. The performance of the cooling system is not fairly represented, however, because the chiller is an ARKLA WF-501 which required a water supply temperature of 90/sup 0/C (195F) to fire.
