Quiet Efficient Electric Natural Refrigerant Heat Pump

Heat pumps play a crucial role in the future climate-neutral heating and air conditioning of buildings. In 2021, heat pumps were used in half of all new buildings. Germany recorded the operation of 1.2 million heat pumps in the same year. The majority of these heat pumps (70%) use air as a source. As their numbers continue to rise sharply, an increasing challenge arises: reducing heat pump noise to a minimum. To meet this challenge, a project network of heat pump manufacturers, component suppliers and research institutes has joined forces to minimize the noise generated by air-to-water heat pumps.

In this project network, the reduction of noise emissions from heat pumps is being advanced in a methods project and in various technology projects. The project network is divided into individual, independent projects, each with a different focus on specific areas for improving heat pumps
