Optimal Design and Performance Analysis of a Refrigeration System for a Fruit Storage

Analyses performed during the design of a fruit storage refrigeration system are presented. Simulation model describing all year round behavior of the cold storage and the refrigeration system has been established and simulations have been performed in order to evaluate optimal insulation thickness of the cold room and energy costs. Costs for energy, equipment and insulation, as well as costs caused by weight loss of the product have been introduced into a cost evaluation model and the complex which consists of storage and refrigeration system has been optimized. Comparison of energy consumption and investment costs between direct expansion and brine refrigeration system has been performed. Direct refrigeration system with higher COP and thus lower energy consumption has been found as the feasible choice. Analyses have also been aimed to the air - cooler design. Oversized evaporators have been chosen in order to maintain high air humidity within the storage and thus decrease the weight loss of stored fruits.
