The Annual Cycle Energy System (ACES) in the ACES demonstration house at the Tennessee Energy Conservation in Housing complex near Knoxville, Tennessee, underwent short-term testing of the minimum ACES design concept and of several alternative energy collection/rejection modes using an outdoor fan coil unit. Operation as a minimum ACES was about as expected. The heating coefficient of performance (COP) was about 4% less than that of a full ACES. the solar panel sizing methods used in an ACES performance modeling code were shown to be conservative for the panel type used at the demonstration house. The system was tested in several modes with an outdoor fan coil in winter and summer. Use of the fan coil as the energy source for the space- and water-heating modes degraded system COP by about 10% over that when the ice bin was used. Ice melting can be done with a fan coil instead of a solar panel, but only if air temperatures exceed 4/sup 0/C for a long enough time during the winter. Using the fan coil as the heat-rejecting mechanism instead of the panel for night heat rejection improved efficiency in that mode by 22% and improved supplemental cooling efficiency by about 5% over the previous year's performance.
