<p>The unit has a closed circuit (10) with refrigerant circulating between evaporator (12) and condenser (14), respectively connected to a cold (22) and a hot fluid line (24). Flow can be switched (34,36) to couple these lines either with a heat exchanger (28) traversed by a stream of air (F1), or a second heat exchanger (42) traversed by a stream of air (F2) to heat or cool the vehicle cabin.</p> |
