1/ mentally friendly [solutions]. People expect long-lasting and ecological” products and places to stay, Koch told Accelerate Europe. Most hotels install a boiler and a separate VRF split air-conditioning (AC) system that traditionally uses high-GWP HFCs. The heat in the other Corbie hotel in Lommel, with solar panels on the roof, is produced by solar energy. Beerten installed that hotel’s HFC-based VRF AC system only later, as air conditioning was not as popular in 2005 when the hotel first opened. “With VRF you need multiple copper piping and leak detectors in every room,” Beerten explains. “[With the TripleAqua] water just goes through, also in the underfloor heating” – a simpler design for the installer, he argues.
hot water as an extremely energy-efficient solution. The other option was to install a separate heat pump to provide hot water to serve the hotel’s entire demand, including the showers. Beerten also looked at integrating solar energy into the hotel’s energy picture. In the end he decided on the TripleAqua together with a separate condensing water heater for hot water production, with no solar panels because the heat pump takes up too much space on the roof. The solar park and wind turbines close to the town serve the hotel’s energy needs.

“I also explained [to the owner of the hotel] that f-gases will be more expensive in the future,” he adds. “Prices of R410A are increasing.” He first met Van der Hoff at an HVAC&R show where the latter was exhibiting the TripleAqua. He approached Filip Van Hulle, sales manager at ECR Belgium (part of the Beijer Ref Group) – who is responsible for TripleAqua sales in Belgium – to discuss various sustainable HVAC&R options. Van Hulle proposed the TripleAqua, to produce all the building’s space heating and cooling in combination with a condensing water heater to produce
