of CO2 emissions is remarkable: in terms of g CO2/kWh usable energy, the prototype has a value of 187 (vs 294 of mainstream HFC models). In terms of g refrigerant/kW heating the prototype shows a value (65) much lower than the state-of-the-art (HFC) HPs in 2012 (200-500). Behind all these remarkable results, there are some important technical novelties. For example the evaporator constructed with multi-port extruded tubes and equipped with a novel bionic refrigerant distributor significantly minimises the refrigerant charge and increases the heat exchangers’ efficiency.
CASE STUDY 3.4.6: A SUSTAINABLE HOTEL THANKS TO HYDROCARBONS 38 Summary: The Corbie Ring Hotel in Belgium, which officially opened its doors in February 2018, opted for the TripleAqua – a complete heating and cooling system that also stores energy – thanks to its efficiency and environmental credentials. The Corbie Ring Hotel in the Belgian town of Lommel is arguably the most sustainable hotel in Belgium. During construction of the hotel the owner opted to install the TripleAqua: an energyefficient heat pump employing the natural refrigerant R290. According to the calculations of a local HVAC contractor, the current setup was the best option, as space heating and cooling is generally responsible for the majority of a building’s energy consumption. It also had the highest payback for the end-user and was the most environmentally friendly solution. Compared to other two recently-built hotels of the same brand, this hydrocarbon-based system is 50% more efficient.
