  • the second exchange zone is formed by a second heat exchanger 25B, separate from the first exchanger 25A.
  • Refrigerant fluid circulates in each air treatment circuit 26A, 26B.
  • Each air treatment circuit 26A, 26B has an exchange surface, allowing the exchange of heat between the refrigerant fluid and the air circulating in the corresponding exchanger 25A, 25B.
  • Each of these first 25A and second 25B heat exchangers forms, for example, part of the air conditioning unit 14 according to conventional heating or cooling technology.
  • first 25A and second 25B heat exchangers comprise electrical heating elements, the air treatment circuits then being electrical circuits.
  • the first 26A and second 26B air treatment circuits are configurable independently of one another.
  • the air treatment can be performed differently for the upper room 12A and for the lower room 12B.
  • the air conditioning unit 14 comprises means 28 for distributing air coming from the outlet 24 of the common chamber 16, towards the first 25A and second 25B exchange zones.
  • the air distribution means 28 are suitable for taking several distinct air distribution configurations towards the first 25A and second 25B exchange zones.
  • the air distribution means 28 are in the third configuration, so that the first 26A and second 26B air treatment circuits receive the same quantity. air from the mixing chamber 16.
  • the air distribution means 28 are able to take at least one intermediate configuration, in which more air is sent to one of the first 25A and second 25B exchange zones, and less air is sent towards the other among the first 25A and second 25B exchange zones.
  • the quantity of air supplied to the first 26A and second 26B air treatment circuits thus depends in particular on the demands for treated air in the upper 12A and lower 12B rooms.
  • the air distribution means 28 comprise at least one removable and / or movable air deflection flap 30, each configuration of the air distribution means 28 corresponding to a respective position of the flap 30.
