| 摘要 |
<p>The invention concerns a device comprising a heat pump (12) including a main refrigerant fluid circuit (14) drawing calories from a cold reservoir (16) to transfer them to a hot reservoir (18), and a cooling circuit (48) for an exothermal element, such as an engine, connected to a cooler exchanger (50). The cold reservoir (16) comprises a first refrigerant fluid/heat transfer liquid thermal exchanger (24) thermally coupling the main circuit (14) to a first auxiliary heat transfer liquid circuit (26) capable of being selectively connected to a so-called external thermal exchanger (30), to a so-called cold thermal exchanger (32) and to the cooler exchanger (50). The hot reservoir (18) comprises a second refrigerant fluid/heat transfer liquid thermal exchanger (34) thermally coupling the main circuit (14) to a second auxiliary heat transfer liquid circuit (36) capable of being selectively connected to the external exchanger (30), a so-called hot thermal exchanger (39) and to the cooler exchanger (50). The invention is useful for air conditioning in a vehicle passenger compartment.</p> |
