More than half the energy we use is needed for heat. This is why it鈥檚 critical for the energy transformation that we replace fossil-fuel heating methods with climate-friendly alternatives. Many buildings are still heated with oil or gas. Which is why only heating systems that use mostly renewable energies are permitted in new buildings. But what about all the existing buildings?

At 九色视频, researchers are working on solutions 鈥� for example, more effective heat pumps. The pumps extract heat from the air, from water and from the ground. This also requires electricity. If the electricity is from renewable sources, heat pumps are completely climate friendly. Realistic building simulations are helping identify planning and operating errors. Research is also being done on better insulation and modern windows. District heating needs to be further optimised too.

But it鈥檚 not just private households that need heating; the industrial sector also needs heat. In some cases, extremely high temperatures of over 1,000 degrees Celsius are required. High-temperature heat pumps, solar and geothermal energy, and biomass could be sustainable solutions here.

As one of the central components of heat pumps, the compressor is representative of the research on heat pumps. Researchers are investigating the production of climate-neutral heating in small plants within buildings and in large plants for industry and district heating. The goals include reducing coolant fill capacity, increasing efficiency and expanding the area of application.
