摘要：

In the present study, the first and second laws of thermodynamics are applied to solar-assisted heat-pump systems. Several relations between first- and second-law efficiency parameters (such as the coefficient of performance, primary energy ratio, exergetic and collector efficiencies) are derived. These relations are used to determine the system performance under realistic operating conditions. The performance of a solar-assisted heat-pump system is compared with that of a solar system without heat-pump. The sources of irreversibilities in the system are identified and their effects on system performance are discussed.
