The properties of the new low-GWP refrigerants have an impact on the performance and efficiency of the refrigeration and air-conditioning systems and their components. The purpose of the seminar is to illustrate through theoretical and experimental results the design approaches leading to an uncompromised system and components performance and efficiency compared to the current refrigerants. The subject of the seminar includes also the performance and efficiency of refrigeration and air-conditioning systems with natural refrigerants, which have the lowest GWP and are a well-established viable alternative to the current refrigerants with high GWP in many applications.
