NH3 AND CO2 STUDY CASES - REFRIGERATION APPLICATIONS
Abstract
The article presents a comparison of the advantages of natural refrigerants R717 or R744 (with low global warming potential ?GWP and zero ozone depletion potential ? ODP) instead of R404A. Energy Efficiency is also analysed. Romania signed Kyoto and Montreal Protocol and in the same time as a new member of EU has the obligation to respect the environmental legislation as Energy Efficiency Directive, Eco-Design Directive, and Regulation 517/2014 cold ?F-Gas? and to solve Certification System in the field of Air Conditioning, Heat Pump and Refrigeration. During the last six years in Romania, the following commercial, industrial and domestic refrigeration fields were developed: pork slaughterhouses, storage rooms, logistic parks, warehouses, farms, beer factories, poultry slaughterhouses, soft drinks factories, diary factories, wine factories, ice rink, and supermarkets. In this paper, the ecological alternatives R717 and R744 are presented in different Romanian refrigeration study cases. Thermodynamic properties of these simulations were done using software Pack Calculation Pro.
