Evaluación energética de un sistema de refrigeración para productores de pollos para la ciudad de Riobamba

Abstract

The purposeof this degree Project entitled: “EVALUACIÓN ENERGÉTICA DE UN SISTEMA DE REFRIGERACIÓN PARA PRODUCTORES DE POLLOS PARA LA CIUDAD DE RIOBAMBA” was to identify and provide a solition to the risk associated with por handling of cicken meat in Riobamba city. For this purpose, an energy evaluation of a refrigeration system for chicken producers in Riobamba city was developed in order to establish the optimal refrigeration conditions that the chicken needs to comply with the cold chain once the animal is slaugtered and delivered to the distributors. This research work began with the collection of information in order to determine the number of chicken producers in the city. Once this data was otained, surveys were conducted to determine the daily or monthly production of chicken meat obtained, in order to determine the refrigeration demand (amount of producto to be refrigerated). Subsequently, of the cold room and the calculation of the termal loads of the refrigeration system were designed, in other words, the appropiate selection of the elements (evaporator, condenser, expansión valve and compressor) by means of catalogs and free-use software. Based on the obtained results, the energy evaluation of the refrigeration system was made throug the calculation of the seasonal COP or SPF (seasonal performance factor). Finally, an economic evaluation of the system was carried out, suggesting the materials and equipment to be used in the construction of the cold room. The use of adequate equipment and instruments was recommended to the producers so that the producto arrives in good condition to the consumer.
