A STUDY ON AN AMMONIA BASED REFRIGERATING SYSTEM USEFUL FOR A MORE EFFICIENT FISHING INDUSTRY

Fishing is an important sector in most developing countries. The Turkish fleet consist of 1566 ships, fishing vessels representing 11% of the total. In the framework of the international competition, Turkish autorities are facing the need to modernize the fishing vessels. In this study is analized a single stage vapor compression refrigerating cycle working with ammonia. Ammonia is environmentally benign in the atmosphere and has a proven safety record. For several values of the compression ratio is analyzed the variation of some parameters of the refrigerating system, being revealed information useful for the plant operation. When it is aimed the plant improvement, it is used the exergy analysis. By estimating exergy destructions in each component of the plant, it is found the first element needed to be optimized.
