Ecological and ecological coefficient performance of an irreversible two-stage absorption refrigeration cycle

Qin, Xiaoyong; Zhang, Kai; Chen, Lingen; Wang, Wenhua (HEFAT, 2017)

An irreversible finite-time thermodynamics models of a two-stage AR (absorption refrigeration) system with variabletemperature heat reservoirs is established, the ecological function and the ECOP (ecological coefficient ...
Optimal process durations of expansion of a heated gas with linear phenomenological transfer law

Song, Hanjiang; Ao, Chenyang; Chen, Lingen; Qin, Xiaoyong (HEFAT, 2017)

An optimal motion of a piston is examined. The piston is fitted inside one cylinder, which contains ideal gas. The gas contacts a heat bath and is heated with given rate f (t) in finite time. The heat transfer between ...
