As the need for the efficient electrification of heating grows, the ability of heat pumps to cover a range of capacities over the course of the year, and to do so efficiently, is more apparent than ever. This seminar focuses on part-load operation of compressors in heating operation. Motivation and context for this topic will be provided with an overview of heat pump compressor design, followed by experimental results displaying the need for partial load behavior in heat pumps. Finally, a range of options and technologies for capacity modulation of heat pumps will be discussed.
