REFRIGERANT FLUID CIRCUIT WITH TWO MEANS OF STORAGE OF REFRIGERANT FLUID.

摘要

The invention relates to a refrigerant circuit 1 for thermally conditioning a passenger compartment of a vehicle, comprising: - a compressor 2 intended to circulate the refrigerant fluid, an internal exchanger 8 arranged to ensure a heat exchange with the cooling fluid in to heat an interior air flow 9 to be sent into the passenger compartment, - a first expansion member 14 installed between the inner heat exchanger 8 and an external heat exchanger 7, the outer heat exchanger 7 being arranged to provide an exchange between the refrigerant and an air flow, said outside air flow 19, disposed outside the passenger compartment, an evaporator 21 arranged to ensure cooling of the internal air flow 9 by heat exchange with the refrigerant, a first refrigerant storage means 23 installed downstream of the first expansion device 14 and upstream of the compressor 2, a second means storage tank 16 of the refrigerant fluid installed between an outlet of a first portion 15, 29 of heat exchange of the inner heat exchanger 8 or the external heat exchanger 7 and the first expansion member 14 the first portion 15, 29 of heat exchange, the second storage means 16 and the first storage means 23 being traversed in this order by the refrigerant, in heating mode of the circuit 1.
