WebA thermodynamic refrigeration cycle removes heat from a low-temperature object (refrigeration) and rejects it at a higher temperature. This cyclic process requires that work be input so that the second law of thermodynamics is not violated (Wark, 1983). The ideal refrigeration system is based on the concept of the reversible Carnot cycle. The ... WebA transcritical cycle is a closed thermodynamic cycle where the working fluid goes through both subcritical and supercritical states. In particular, for power cycles the working fluid is kept in the liquid region during the compression phase and in vapour and/or supercritical conditions during the expansion phase.
