A system for providing a vapour compression cycle, comprises a compressor (1 ). A first heat exchanger (2) is arranged downstream of the compressor (1 ), and a first pressure reduction device (5) lies downstream of the first heat exchanger (2). A second heat exchanger (6) with a heat storage device (7) lies downstream of the first pressure reduction device (5), and a second pressure reduction device (3) is provided downstream of the second heat exchanger 6. A third heat exchanger (4) lies downstream of the second pressure reduction device (3) connected back to the compressor 1. A bypass line with a shutoff valve (8), bypasses the third heat exchanger (4), connected at a first end between the second heat exchanger (6) and the second pressure reduction device (3) and at a second end, between the third heat exchanger (4) and the compressor (1 ). At least one control unit controls at least the shutoff valve (8) and the second pressure reduction device (3) and the first pressure reduction device (5). |
