Abstract (en)
[origin: WO2013117187A2] The invention relates to a heat pump apparatus, comprising a compressor (1), downstream of which a liquefier (2) is connected, downstream of which a refrigerant collector (3) is connected that, for the intermediate injection of refrigerant into the compressor (1), is connected to the compressor via a refrigerant line (4). According to the invention, in order to set the refrigerant level in the refrigerant collector (3), a controllable expansion valve (5) is arranged between the liquefier (2) and the refrigerant collector (3) and, depending on the setting of the expansion valve (5), the refrigerant line (4) has a refrigerant feed opening (6) opening above and/or below the refrigerant level during the operation of the heat pump apparatus.
