    摘要: A thermal management device having an indirect air conditioning circuit for a motor vehicle is disclosed. The device has a first refrigerant fluid loop (A) with a compressor, a two-fluid heat exchanger, a first expansion device, an evaporator, a second expansion device, an evaporator/condenser, and a first by-pass line including a first stop valve, a first and a second internal heat exchanger. A second by-pass line includes a third expansion device arranged upstream from a cooler, a shunt branch comprising a first external radiator. The device also has a second heat transfer fluid loop (B) in which a heat transfer fluid is intended to flow. The two-fluid heat exchanger is arranged jointly on the one hand on the first refrigerant fluid loop downstream of the compressor, between said compressor and the first expansion device, and on the second heat transfer fluid loop (B).
