Air-water heat pumps now enjoy a high level of acceptance in heating technology and are becoming an important pillar of more sustainable heat generation. There is demand for efficient and, most importantly, quiet systems suitable for indoor, outdoor or hybrid use, which use natural refrigerants and whose output can be intelligently adapted to the actual conditions. ebm‑papst presented the efficient AxiEco axial fans in various designs at the beginning of 2020. Thanks to their high pressure stability, ventilation and air conditioning devices in particular benefit from higher air flow volumes. The series has now been expanded with the new AxiEco plug-in fans in sizes 450 and 500, which are typical for heat pumps in detached or semi-detached homes. Pressure-resistant in the face of ice formation Ice formation is a big topic in the world of heat pumps. It is a particular issue for evaporators when humidity settles on the heat exchanger as ice at cold ambient temperatures. This reduces the air routes and the drag. The fans then have to offer significantly greater pressure reserves. This is where the new AxiEco Plug-in comes in. Studies have shown that its flow technology reduces ice formation and its air flow only reduces very slightly as the pressure increases. This is also an advantage for heat pumps, which heat in winter and cool in summer, as the operating points then vary depending on operation.
