Predicting the discharge line temperature (DLT) of air conditioning and refrigeration compressors is important to ensure sufficient lubricant properties and proper performance of components that are positioned in the exhaust stream.Numerous comprehensive prediction models have been developed with excellent accuracy, but require many details of a particular compressor. This paper assesses various DLT prediction methods that do not compressor-specific parameters. It presents a semi-empirical model with a accuracy that significantly exceeds the other established methods. The model is applied to both traditional refrigeration and vapor-injected, economizer cycles. Lastly, a study was conducted to determine the relationship between the accuracy of the model and number of experimental points used to produce the model.
