3 9 Rooftop Systems
There is currently no ban on new HFC-based rooftop HVAC equipment included in the F-Gas Regulation’s Annex III. As done with the other sectors where no ban was introduced, the survey looked at how this lack of a market prohibition has affected the sector in terms of 1) increasing the uptake of climate-friendly alternative technologies; 2) increasing the development of climate-friendly alternative technologies; and 3) increasing the price competitiveness of climate-friendly alternative technologies.
Sixty-five percent of survey respondents said it slowed the uptake of climate-friendly alternative technologies, while 70% said it also slowed the development of such technologies. Sixty-five percent believed that it negatively impacted the price competitiveness of alternative technology.
Respondents were asked if they thought this sector would have fully converted to natural refrigerants by now had sectoral ban had been included for 2020.
When asked whether they support a full ban on HFC-based equipment in rooftop systems by 2024, 65% said they did.
Figure 3.9.1 Do you support a full ban on new HFC-based equipment in the rooftop systems sector by 2024?
23 responses
In the rooftop HVAC systems sector, 35% of survey respondents indicated propane as their refrigerant of choice, listing the main reason as “good performance” and its environmental sustainability. The rest of the responses were similarly split between the remaining options with HFOs being favoured least.
