<p>An air-conditioning loop, in which a refrigerant flows, is capable of operating as a heat pump. The air-conditioning loop includes a compressor. The air-conditioning loop further includes a first solenoid valve connected to the compressor, to a radiator, and to an external heat exchanger. The radiator is connected to the external heat exchanger via a first pressure-release device and to an evaporator via a second pressure-release device. The evaporator is connected to the compressor. The external heat exchanger is connected to the compressor and to the evaporator via a second solenoid valve. The external heat exchanger, the first solenoid valve, and the second solenoid valve constitute a unitary part.</p> |
