TY - JOUR T1 - LABORATORY REFRIGERATION UNIT WITH STEAM-JET COMPRESSOR AU - Georgıev, Vasil AU - Nenov, Nenko PY - 2018 DA - June DO - 10.36222/ejt.468476 JF - European Journal of Technique (EJT) JO - EJT PB - Hibetullah KILIÇ WT - DergiPark SN - 2536-5010 SP - 13 EP - 16 VL - 8 IS - 1 LA - en AB - Alaboratory refrigeration unit with steam-jet compressor has been developed. Itfeatures implementation of steam-jet compressor for chilling of water atpositive boiling temperatures. The source of energy for negative refrigerationprocess is by means of heat input. The unit could be used for measuring andconsequent analysis of energy transformation values of present method fordifferent temperatures of heat source, cooling media and environment. Theconstruction allows exploring of these for different traditional and novelsingle-compound refrigerants due to its changeable ejector and expansionvalve.The unit is a step before its industrial application.
