Beschreibung
Zusammenfassung:	A heat pump includes a refrigerant loop. The refrigerant loop includes a compressor, a first region of a first heat exchanger, a second heat exchanger, and a bypass branch. The compressor includes a low-pressure inlet, a mid-pressure inlet, and an outlet. The first heat exchanger is positioned downstream of the outlet of the compressor. The second heat exchanger is positioned downstream of the first heat exchanger. The bypass branch includes an entrance and an exit. The entrance to the bypass branch is positioned downstream of the outlet of the compressor and upstream of the first region of the first heat exchanger. The exit of the bypass branch is positioned upstream of the second heat exchanger.
