Toshiba Carrier UK (TCUK) believes uncertainty around the future direction of air conditioning technology will remain until refrigerant issues have been resolved.
David Dunn, managing director sales, says the choice between VRF and chillers is a "critical question'' for the industry and believes TCUK is well placed to deliver solutions whatever the outcome.
"We believe the dominant solution won't become clear until the current uncertainties over refrigerant options have been resolved. However, we are evaluating a number of alternatives and customers can rest assured that with our leadership in both areas of technology, we will have a proven, best-in-class solution that will exceed efficiency and environmental requirements."
The latest revisions to the F-Gas Regulations have implications for the availability of HFC refrigerant, which is now subject to a progressive phase-down under a European Union quota system as a result of its high Global Warming Potential (GWP).
Mr Dunn added that the transition from chillers to VRF systems in the 1980s and 90s marked a watershed in terms of technology. But a settled picture over the past three decades was now being challenged, he said, with chillers looking to reclaim ground taken by VRF technology.
He said: "Given the uncertainties, people are understandably nervous. However, our message to customers is – we are confident that we have all the bases covered, in both VRF, chiller and rooftop categories. Between them, TCUK's leading brands will continue to deliver innovative, efficient and reliable products that offer outstanding performance for building owners, occupants and the environment."
