EVRCs (ejector-expansion vapor-compression refrigeration cycles) applied in domestic refrigerator-freezers have been concerned duo to their potentials of improving cycle performance. However, the previously presented EVRCs with various cycle configurations are still limited to favorable...

In this study, a novel solar-assisted auto-cascade heat pump cycle (SAHPC) operating with the zeotropic mixture of R32/R290 for small water heaters is proposed. In the SAHPC system, a cascade heat exchanger (CHEX) associated with a phase separator is used to achieve auto cascade cycle and...

In this paper, a transcritical ejector refrigeration cycle (TERC) using refrigerant R143a as working fluid is proposed to improve the performance of the ejector refrigeration systems driven by low-grade thermal energy. This method adopts an adequate combination of thermal and mechanical energy...

In this paper, exergy method is applied to analyze the ejector expansion Joule–Thomson (EJT) cryogenic refrigeration cycle. The exergy destruction rate in each component of the EJT cycle is evaluated in detail. The effect of some main parameters on the exergy destruction and exergetic...

This paper provides tools for partial identification inference and sensistivity analysis in a general class of semiparametric models. The main working assumption is that the finite-dimensional parameter of interest and the possibility infinite-dimensional nuisance parameter are identified...
