摘要

Pumps for solar domestic hot water (SDHW) systems are often assumed to operate efficiently and inexpensively since they are relatively small. However, analysis and testing of these pumps at the Solar Energy Research Institute (SERI) showed that these pumps operate at low efficiencies and that the operating costs can be substantial for certain types of SDHW configurations and control strategies. Possible solutions for this problem are presented. (ERA citation 08:040541)
