A decade of intensive research and development in the implementation of natural refrigerants in refrigeration and air-conditioning resulted in a large number of supermarket refrigeration systems worldwide that were designed, commissioned, and have been in operation sufficient time to assess their performance, efficiency, and environmental impact. This seminar presents a review of refrigeration systems using natural and low-GWP substances as refrigerants. The real-life performance and efficiency of these systems will be provided and compared to the simulation predictions during the design phase.
