Summary

The refrigerated transport industry is actively looking for innovative alternatives to mechanically refrigerated systems to ones with higher efficiency and lower environmental impact, for example, on carbon footprint and noise level. Recent industrial developments of cryogenic units offer serious alternatives. They are environmentally friendly, with energy efficiency and especially with the use of indirect heat exchangers for the liquid nitrogen, operate in complete safety. In this article, the authors present an experimental approach to test and qualify the energy performances of a multi-temperature cryogenic unit using indirect closed heat exchangers for liquid nitrogen, or any other liquid cryogen. The protocol is based on the multi temperature protocol developed for ATP, which has been in use for more than 15 years. Beyond the provision and analysis of the technical results for the cooling capacity of each of the tested configurations, at 0 and -20°C the authors make technical recommendations in order to successfully achieve such qualification.
