Dataset of Comprehensive Thermal Performance on Cooling the Hot Tube Surfaces of Vortex Tube at Different Pressure and Fraction

摘要

The performance of the vortex tube is low compared to a conventional heat pump engine based on Freon refrigerants, and therefore, there is a need for an experiment on how to improve its efficiency. This data article aims to analyze the effect of the new vortex tube design on cold temperature ( ), hot temperature ( ), delta cold temperature (Δ ), delta hot temperature (Δ ), heat transferred as cooling effect , heat transferred as heating effect , isentropic efficiency as cooling effect ( ), isentropic efficiency as heating effect ( ), the coefficient of performance refrigeration ( ), and coefficient of performance heat pump ( ), which is tested based on pressure and fraction variations. The data were obtained from the experimental measurements. Data were collected at conditions with temperature controlled at 27 ± 0.1°C. All measuring instruments were supposed to be consistent for at least 5 min for data to be collected, although retrieval was conducted 4 times.
