As Viessmann aims for climate-neutrality across its entire value chain by 2050, an accelerated shift to heat pumps based on natural refrigerants like propane will be crucial.
The R290 glycol-based Hydroloop system from Freor system was installed in a Fajne Potraviny store in Košice in early 2022.
EU-based producers reported a 25% average increase in the price of high-GWP refrigerants like R404a, R410a and R134a.
Using a natural refrigerant, the system will have minimum ecological impact and ensure energy optimization.
Ban on certain stationary split air-conditioning and split heat pump equipment containing f-gases would help adoption of R290 equipment.
NGOs don’t think it goes far enough in rolling back HFCs, while trade groups fear it is too ambitious and will impair heat pump deployment
The move is part of a DKR 2.5 billion (US$366 million) investment in energy efficiency and an effort to reduce Salling Group’s reliance on Russian gas.
The reversible heat pumps provide both space heating and cooling for the warehouse and offices.
The four TAE N Mini chillers offer cooling capacities from 1.7kW (0.48TR) to 4.4kW (1.3TR).
The move is a response to increased market demand and will focus on products using propane and CO2.
