Heat pumps have long become standard, especially in new buildings. To operate them in a climate-friendly way, electricity from renewable sources must be used. The choice of refrigerant is also important, as some have a negative effect on the climate. That’s why we have used natural refrigerants such as ammonia for years and have gained a great deal of expertise in handling them.>

Text: *GWP (global warming potential) = 100 years of greenhouse gas potential ** Though HFOs are not harmful to the climate, when released they produce trifluoroacetic acid, which can have fatal consequences for the water supply due to their toxicity and low degradability. Overview of the climate impact of selected natural and synthetic refrigerants. (Source: FOEN 2020)
