This paper presents the simulations and experiments for development of a hybrid reversible mobile air conditioning, organic Rankine cycle (ORC), ejector refrigeration (ERC) system. flexible compact system may be solution to introduction waste heat recovery in passenger cars. The fuel economy is calculated series electric vehicles (SHEVs). A global vehicle model used simulate annual weather cond...

The objective of this paper is to explore whether the use of an internal heat exchanger can further improve the performance of transcritical ejector systems with C02 as the working fluid. Instead of using a simplified thermodynamic cycle analysis, the approach taken here is based on a more elaborated and experimentally validated system model for a real mobile air-conditioning system for a typic...

This communication presents finite time thermodynamic optimization of irreversible cascaded refrigeration and heat pump cycles having source/sink thermal reservoirs of finite heat capacitance. A general expression for the optimum coefficient of performance of the refrigerator/heat pump is derived at minimum power input and given cooling/heating load conditions, respectively. External irreversib...
