Rotary piston compressor and system for temperature conditioning with rotary piston compressor

A system comprising:

• a rotary piston compressor (1) for temperature conditioning, the rotary piston compressor having,
• a rotor (19) mounted in a housing (21),
• wherein the rotary piston compressor (1) is designed in such a way that the rotor (19) rotates in a first direction in a first operating state and rotates in a second direction opposite to the first direction in a second operating state,
• and wherein, in the first operating state, a first compressor connection (3) is designed to supply a heat transfer medium (17), and a second compressor connection (5) is designed to discharge the compressed heat transfer medium (17),
• and wherein, in the second operating state, the second compressor connection (5) is designed to supply the heat transfer medium (17), and the first compressor connection (3) is designed to discharge the compressed heat transfer medium (17);
• a pressure reducer (7, 1) having a first pressure reducer connection (9, 37) and a second pressure reducer connection (11, 39), wherein the pressure reducer (7, 1) is designed to reduce a pressure of the heat transfer medium (17) flowing through it and to cause it to expand, and a first heat exchanger (13) coupled between the first compressor connection (3) and the first pressure reducer connection (9, 37);
• and
• a second heat exchanger (15) coupled between the second compressor connection (5) and the second pressure reducer connection (11, 39);
• wherein use of the system for temperature conditioning is used in a vehicle, wherein the first heat exchanger (13) is positioned in such a way that it gives off heat to a passenger compartment or cools it, and wherein the second heat exchanger (15) is positioned in such a way that it gives off heat to the surroundings beyond the passenger compartment or receives heat from it;
• wherein the rotary piston compressor (1) has a third compressor connection (37) and a fourth compressor connection (39),
• wherein, in the first operating state, the fourth compressor connection (39) is designed to supply the heat transfer medium (17), and the third compressor connection (37) is designed to discharge the expanded heat transfer medium (17),
• and wherein, in the second operating state, the third compressor connection (37) is designed to supply the heat transfer medium (17), and the fourth compressor connection (39) is designed to discharge the expanded heat transfer medium (17).
