Annual cycle energy system experimental performance and national applicability
A single-family residence in Knoxville, Tennessee has been used to demonstrate the energy conserving potential of the Annual Cycle Energy System (ACES). For the past two years the performance of the ACES has been compared with that of two different air-to-air heat pumps in an identical house, the control house. The two heat pumps had ARI-rated COPs of 2.46 and 3.11 at 8.3/sup 0/C, representing both standard and best available heat pumps now on the market. Hot water for the control house was supplied by an electric resistance heater each year, while hot water for the ACES house was supplied by the ACES mechanical package. Performance results for the period December 1978 through September 1979 show that the ACES consumed 6719 kWh of electricity for an annual coefficient of performance (ACOP) of 2.80. The control house (with the ARI-2.46 heat pump) consumed 12,853 kWh of electricity, yielding an ACOP of 1.42. For December 1979 through September 15, 1980, the ACES consumed 6447 kWh of electricity for an ACOP of 3.08 while the control house, using the ARI-3.11 heat pump, consumed 11,358 kWh for an ACOP of 1.73. The ACES has achieved nearly all of its theoretical performance predictions and has verified its design criteria. This system has delivered residential heating and cooling services while consuming only 57% as much electricity as the best conventional alternative tested. Computer studies have shown the ACES to be applicable to all US climatic zones except those with very low heating needs.
