abstract

An irreversible solar-driven heat pump system operating among three heat sources at different temperatures is investigated, in which not only finite-rate heat transfer between the cycle working fluid and the three heat sources but also the internal irreversibility inside the cyclic working fluid, the radiation heat loss of the solar collector are taken into account. Based on thermodynamics analysis method and the optimal control theory, the relation between the overall coefficient of performance (COP) of the solar-driven three source heat pump system and the operating temperature of the solar collector is derived. An optimal matching between the solar collector and the three source heat pump is determined and the optimal operating temperature of the solar collector is explored. Furthermore, the influences of the radiation heat loss of the collector, the internal irreversibility and the comprehensive factor, etc. on the performance characteristic of the solar-driven three source heat pump system are analyzed and evaluated. By means of the numerical value calculation, the optimal design parameters and performance characteristics of the solar-driven three source heat pump system are discussed in detail. The results obtained may provide some theoretical references for the parametric design and performance evaluation of solar-driven absorption/adsorption heat pumps.
