摘要

Cooling performance characterization tests were performed at the GRI Home Systems Research House located in the NAHB Research Home Park in Prince George's County, Maryland. Test protocols followed guidelines set forth in GRI's Research House Utilization Plan (RHUP). A combination of minute-by-minute and hourly average data consisting of weather, comfort, and energy parameters was collected by using an automated data acquisition system. The tests were performed from July 1991 through September 1991. The gas heat pump (GHP) had an average daily gas coefficient of performance (COP) value of 1.49 at an outdoor temperature of 72.8 F and 0.84 at an outdoor temperature of 83.9 F. The average test period gas COP was 1.13. The GHP peak cooling capacity achieved was approximately 34,000 Btuh. The GHP provided good overall thermal comfort control on the first-floor and moderate thermal comfort control on the second floor. Reduced second floor performance was primarily due to thermostat location and the 'stack effect.' Good latent heat removal existed throughout the test period. Unit modulation kept room air stratification to a minimum. Thermostat setback saved energy at high average daily outdoor temperatures and used more energy at lower average daily outdoor temperatures, compared to a constant thermostat setpoint control, due to changes in unit gas COP values from low-speed to high-speed operation.
