Abstract

A climate control device for stationary control of the climate in a motor vehicle has a heat pump circuit with a first heat exchanger for taking up ambient heat and a second heat exchanger for discharging heat into the vehicle interior and an electrically or mechanically drivable compressor which is located in the flow direction of the heat pump circuit between the first and the second heat exchanger, and a booster set for producing electrical or mechanical power, the electrical or mechanical power being used at least in part to drive the compressor. In addition, there is a third heat exchanger by which the exhaust heat of the booster set is transferred to the heat pump circuit. In this way, good efficiency is ensured for the climate control device in heating operation in stationary operation.

Claims

1. Climate control device for stationary climate control of a motor vehicle, comprising:

a heat pump circuit with a first heat exchanger for taking up ambient heat and a second heat exchanger for discharging heat into the vehicle interior, and compressor which is located between the first heat exchanger and the second heat exchanger in a flow direction of the heat pump circuit,

a booster set for producing power, the power provided at least in part to the compressor for driving it, and

a third heat exchanger by which exhaust heat of the booster set is transferred to the heat pump circuit.

2. Climate control device as claimed in claim 1, wherein the third heat exchanger is located between the first heat exchanger and the compressor in the flow direction of the heat pump circuit.

3. Climate control device as claimed in claim 1, wherein the heat pump circuit is filled with a CO₂ refrigerant.

4. Climate control device as claimed in claim 1, wherein an additional heat exchanger is provided in an air flow path through the second heat exchanger and to which heat from the booster set is supplied for further heating of the air flow.

5. Climate control device as claimed in claim 1, wherein an electrical heating element is provided in the air flow through the second heat exchanger.

6. Climate control device as claimed in claim 1, wherein, in a second operating mode, individual components of the heat pump circuit are operated to cool the vehicle interior.

7. Climate control device as claimed in claim 6, wherein the compressor is a component which is operable in the second operating mode.

8. Climate control device as claimed in claim 1, wherein the booster set is a fuel cell booster set.

9. Climate control device as claimed in claim 1, wherein the booster set is an internal combustion engine-generator unit which enables the climate control device to be operated independent of a vehicle engine.
