Energy Analysis of a Coupled Power and Refrigeration Cycle
This paper presents the energy analysis of a coupled power-refrigeration cycle which eliminates the requirement of electrical power for driving the compressor of the vapour compression refrigeration cycle. The coupled cycle which uses R-134a as working fluid in the topping power and bottoming refrigeration loop have been assessed with different combinations such as cycle with recuperator and cycle with recuperator, reheater and economizer with a view to augment the performance. At the condenser temperature range of 30-42℃, the COP of the coupled with the introduction of the recuperator, increased by 60％ and in the cycle with recuperator, reheater and economizer, it increased by 80％. It is found that at elevated condenser temperatures, the decrease in COP and increase in mass flow rate in power cycle can be compensated by increasing the temperature of the refrigerant vapours at the inlet of the turbine at the same pressure.
