Cascade system, two stage refrigeration system, coefficient of performance, various refrigerant
In this paper a review of Cascade refrigeration system is done. It is a combination of two or more vapour compression refrigeration system used for low temperature refrigeration. Various experimental studies has been carried out by using different combination of refrigerant to improve overall Coefficient of Performance, evaluating the condenser, evaporator temperature and pressure, cooling capacity, energy saving and environmental aspects. Review says use different combination refrigerant meet the desired conditions.
