Performance Analysis of Solar Assisted Cascade Refrigeration System of Cold Storage System
By preserving food products in the cold storage, good quality of food can be supplied throughout the year, minimizing the damage and enhancing the agricultural economy. Huge amount of electric energy is required to run a cold storage. Minimizing the use of electrical energy or proper utilization of electrical energy and thus by enhancing the COP would definitely be the major factor for sustainability of the cold storage and the decrease of the price of preserving the food in it. Theoretical modeling of solar-assisted cascade refrigeration system in cold storage is studied in this work. The system consists of electricity-driven vapor compression refrigeration system and solar-driven vapor absorption refrigeration system. The vapor compression refrigeration system is connected in series with vapor absorption refrigeration system. The results shows higher COP as compared with the conventional vapor compression refrigeration system. COP of this type refrigeration system increases as sunlight becomes intense.
