APPA and PWP Conclude ACDC12 Hybrid Solar Air Conditioner DEED Study with Webinar
Pasadena Water and Power, (PWP) and D48 recently concluded their ACDC12 hybrid solar heat pump study with a webinar through the American Public Power Association’s, (APPA) Demonstration of Energy & Efficiency Developments, (DEED) grant program.
APPA’s DEED grant allowed PWP to third party monitor and report the results on the 1-Ton ACDC12 which uses solar power during the day with utility power mixed in as needed. At night and in low light the ACDC12 seamlessly transitions into a 22-SEER split heat pump system.
Key results from the DEED study found that the grid independent ACDC12 solar component can use up to 20-Amps of direct current PV input and that this unique combination of direct current and alternate current power resulted in a COP of up to 7.5 in cooling mode. Other findings included the need to place the ACDC12 system in 400-800 square foot spaces to avoid under sizing, that the best application is small commercial and the system’s light AC Amp demand blends well with power panels nearing capacity.
