Over the last few years, technology providers surprised the HVAC&R industry with the development and introduction of fluorinated refrigerants that has low-GWP characteristics close or similar to natural refrigerants. With start in deploying those refrigerants commercially in automobile industry for Vehicles air-conditioning particularly in Europe, people start to wonder if HFOs can also be considered as long-term solutions in different HVAC&R applications other than MAC.

Availability, cost, blend composition considerations and safety are questions being raised lately by the industry to the newly developed HFOs that started to be promoted as alternative for commercial refrigeration and Air-Conditioning applications. Availability of compressors designed for HFOs is another concern that also being raised.

This Webinar will try to shed light on those concerns through presenting feedback from industry and end users worked with HFOs and what are potentials, challenges and expectations associated with its use. The Webinar should allow experts from the field to discuss and seek clarifications directly from the technology providers and end-users.

This Webinar is the second of a series titled “REFTALK” aiming at presenting in depth the new commercially or potentially available refrigerants in different sectors,
The OzonAction Webinar aims at providing a platform to share your expertise engaging with worldwide participants in an informal atmosphere.
