Abstract
A heat pump system includes a first heat pump arrangement having a compressor having a compressor output; a second heat pump arrangement having an input portion and an output portion; and a coupler for thermally coupling the first heat pump arrangement and the second heat pump arrangement, the coupler including a first heat exchanger and a second heat exchanger, the first heat exchanger being connected to the input portion of the second heat pump arrangement, and the second heat exchanger being connected to the output portion of the second heat pump arrangement.
Claims20
Heat pump system comprising:
- a first heat pump arrangement comprising a compressor comprising a compressor output;
- a second heat pump arrangement comprising an input portion and an output portion;
- and
- a coupler for thermally coupling the first heat pump arrangement and the second heat pump arrangement, the coupler comprising a first heat exchanger and a second heat exchanger, the first heat exchanger being connected to the input portion of the second heat pump arrangement, and the second heat exchanger being connected to the output portion of the second heat pump arrangement,
- wherein a working liquid within the first heat pump arrangement comprises CO2, or a working liquid within the second heat pump arrangement comprises water.
Heat pump system as claimed in claim 15,
- wherein a connection between consumption of the electrical power and the temperature prevailing at the input portion or the output portion is approximately linear at least in one operating mode of the second heat pump arrangement, or
- wherein the second heat pump arrangement comprises a turbocompressor comprising a radial impeller, a rotational speed of the radial impeller being controllable as a function of the temperature prevailing at the input portion or at the output portion.
Method of producing a heat pump system comprising a first heat pump arrangement comprising a compressor comprising a compressor output;
- and comprising a second heat pump arrangement comprising an input portion and an output portion, the method comprising:
- thermally coupling the first heat pump arrangement and the second heat pump arrangement while using a first heat exchanger and a second heat exchanger, by connecting the first heat exchanger to the input portion of the second heat pump arrangement, and by connecting the second heat exchanger to the output portion of the second heat pump arrangement,
- wherein a working liquid within the first heat pump arrangement comprises CO2, or a working liquid within the second heat pump arrangement comprises water.
Method of operating a heat pump system, comprising:
- operating a first heat pump arrangement comprising a compressor comprising a compressor output;
- operating a second heat pump arrangement comprising an input portion and an output portion;
- and
- thermally coupling the first heat pump arrangement and the second heat pump arrangement while using a first heat exchanger and a second heat exchanger, the first heat exchanger being connected to the input portion of the second heat pump arrangement, and the second heat exchanger being connected to the output portion of the second heat pump arrangement,
- wherein a working liquid within the first heat pump arrangement comprises CO2, or a working liquid within the second heat pump arrangement comprises water.
