Abstract
The apparatus comprises a heat pump () having a main refrigerant circuit () taking heat from a cold source () and transferring it to a hot source (), and a cooling circuit () for cooling an exothermal part, such as an engine, the cooling circuit being connected to a cooling heat exchanger (). The cold source () has a first refrigerant/coolant heat exchanger () thermally coupling the main circuit to a first secondary coolant circuit () capable of being selectively connected to an 'outside' heat exchanger (), to a 'cold' heat exchanger (), and to the cooling heat exchanger (). The hot source () has a second refrigerant/coolant heat exchanger () thermally coupling the main circuit () to a second secondary coolant circuit () capable of being selectively connected to the outside heat exchanger (), to a “hot” heat exchanger (), and to the cooling heat exchanger (). The invention is applicable to air conditioning a vehicle cabin.
