This work reports an experimental investigation related to the drop-in process of HCFC22 in a commercial refrigeration system with a maximum capacity of 15 kW. Among the alternative refrigerants there are hydrocarbons (HCs) and synthetic refrigerants, HFC. The experimental facility is basically composed of analternative variable speed compressor (VSC), tube in tube heat exchangers and an electronic expansion valve (EEV). Different methodologies were addressed to this document. Initially, the systemoperated at the nominal frequency and has been configured to the same openning condition in the expansion valve. The limits of the refrigeration system were operated by factorial experimental designs. Therefore,there were presented response surfac...
