EFFECTS OF PURGING NON-CONDENSABLE GASES FROM AMMONIA REFRIGERATION SYSTEM

Abstract

This paper analyzes the operational characteristics of the Tuzla brewery refrigeration system after the installation of the Danfoss IPS8 air purging device. In order for an analysis such as this to be conducted correctly, one must understand where in the brewing industry the need for refrigeration occurs, how non-condensable gases are accumulated inside of the refrigeration system, and how the separation of non-condensable gases is done. After the theoretical part of the analysis, in which the thermodynamic basics of the ammonia refrigeration cycle is explained, an analysis of annual savings was conducted. The results of the analysis are presented in the form of annual savings in electricity consumption, for different operating conditions of the specific refrigeration system with and without a purger. At the end of this analysis, the amount of released non-condensable gases were also calculated.
