Transport refrigeration with a transcritical refrigeration cycle using carbon dioxide as refrigerant.

Author(s) : SONNEKALB M., KOELHER J.

Summary

CO2 is a natural refrigerant with negligible global warming potential. A laboratory prototype was tested according to the German standard DIN 8958. The cooling capacity was measured in a calorimeter test cell. At a constant ambient air temperature of 30 deg C the temperature of the cold room was varied between -20 and 12 deg C. The operating conditions for the laboratory prototype stayed in an acceptable range, even for ambient air temperatures up to 47 deg C. The measurements results are presented and discussed, and the potential of further improvement is pointed out. In addition, componenets of the transcritical cycle are discussed. The laboratory test results show that CO2 is an interesting alternative refrigerant for future transport refrigeration applications.
