LABORATORY REFRIGERATION UNIT WITH STEAM-JET COMPRESSOR

Abstract

A laboratory refrigeration unit with steam-jet compressor has beendeveloped. It features implementation of steam-jet compressor for chilling ofwater at positive boiling temperatures. The source of energy for negativerefrigeration process is by means of heat input. The unit could be used formeasuring and consequent analysis of energy transformation values ofpresent method for different temperatures of heat source, cooling media andenvironment. The construction allows exploring of these for differenttraditional and novel single-compound refrigerants due to its changeableejector and expansion valve.The unit is a step before its industrialapplication.
