Estudo de caso: eficiência energética em sistemas de climatização por água gelada

Abstract

The energy eficiency in systems of air conditioning by expansion of cold water or indirect expansion is directly related to the equipament that composse the air conditioning circuits and the technology determines the last comsumption of eletric energy. The case study aims to demonstrate the energy and economic viability of the modernization of the systems for the generation of cold water indirect enclosure air conditioning. The method of camparison of the results of the performance indexes of the sistems that generate the chilled water for the last use in air conditioning currently installed and the proposed indexes to modernize the installations is applied, being possible to determine the energy gain and the financial investiment through the matematical model of ANEEL, as well as its brief financial return through the calculation of the pay back. The results obtained demonstrate the benefits to the user, after applying the methodology and the modernization and technological upate of the systems of environmental conditioning by ice water.
