Shutyuk // Ukrainian Journal of Food Science. – Kиїв, 2013. – Vol.1, Issue1. – P. 111–115.https://dspace.nuft.edu.ua/handle/123456789/8307The article describes thermodynamic methods as well as optimization methods of heating and heat exchanging engineering system of sugar industry. The authors suggest noncyclic approach to the analysis of efficiency of heat exchanging apparatus, the basis of which is irrefutable fact that irreversibility as physical reason of inefficiency of technical heat engineering systems really exists. Thermodynamic analysis, which was mentioned in the article, assumes determination of measure of irreversibility of processes in the apparatus and energetic efficiency of apparatus in the whole with the help of exceptionally entropy. The measures taken to improve energetic efficiency of apparatus of saccharine factory on the example of the first group of juice heating in front of evaporator system using the given methodology, were fully analyzed.enthermodynamicsheat exchangeprocessentropyexergy of warmthтермодинамікатеплообмінпроцесентропіяексергіятермодинамикатеплообменпроцессэнтропияэксергиякафедра теплоенергетики та холодильної технікикафедра технології консервуванняArticle
