另一类传热规律下三热源热泵的生态学优化性能

An Ecological Criterion Optimization of a Three-Heat-Source Heat Pump for Another Heat-transfer Law

以生态学函数为目标，研究传热规律为q△（1／T）的三热源热泵的优化性能，获得一些新的性能界限。结果表明，生态学优化准则可使三热源热泵的供热率和火用耗散率达到最佳的折衷，从而它可为热泵的优化设计和最佳工况选择提供些新理论指导。

The optimal performance of a three-heat-source heat pump for the heat-transfer law of q △(1/T) is studied by taking an ecological criterion as an objective function, and some new performance bounds are derived. It is shown that the ecological optimal criterion can make the best compromise between the rate of heat pumping and the exergy dissipation of the three-heat-source pump, and so may provide some new theoretical guidance for the optimal design and the selection of optimal operation condition of the heat pump.
