ABSTRACT
A commercial-scale ice pond refrigeration System (IPS) with a 1200 m3 ice pond was operated to store potatoes for a period of seven months until the early summer following the harvest and its energy balance was analyzed. The system COP (Coefficient of Performance) for ice making was about 20, that for cooling was about 1.7 and the cycle system COP of the IPS was about 1.4. These COP values demonstrated the energy-saving performance of the IPS when compared with a conventional refrigeration system. The heat gain from the top surface of an ice pond forms about haw of the total heat load on the ice pond. But, when the IPS is employed for only potato storage by using a minimum quantity of ice, about 50 % of latent heat accumulated in the manufactured ice can be used efficiently for cooling of a storage warehouse.HomePageKeywords: ice pond refrigeration system, energy balance, ice making, refrigeration, storage, coefficient of performance
