[0101] According to the first embodiment of the invention, the first air inlet 3 admits the external air flow Fe and the second air inlet 4 admits the recirculation air flow Fr. Configurations of this type are shown in the figure 1 middle.

[0102] according to figure 1 In the embodiment, the first air inlet flap 17 prevents the external air flow Fe from entering the shell 2 to pass through the first heat exchanger 5 while allowing the recirculation air flow Fr in the air inlet duct 23 to enter the first heat exchanger 5 entirely. In this configuration, the second air inlet flap 18 allows the flow of external air Fe to enter the housing 2 . The external air flow Fe is guided in the air circulation channel 24 .

[0103] Afterwards, the internal air flow Fi is sucked by the electric fan 8 . The internal air flow Fi is then propelled towards the part of the housing 2 housing the second heat exchanger 6 .

[0104] According to a second embodiment of the invention, the first a...

Abstract

The invention relates to a heating, ventilation and / or air-conditioning apparatus (1) for the passenger compartment of a motor vehicle, including a housing (2) comprising a first air inlet (3) and a second air inlet (4) and directing an inner air flow (Fi) from the first air inlet (3) and / or the second air inlet (4), wherein the housing (2) contains at least a first heat exchanger (5). The housing (2) includes: an air flow channel (24) directing the inner air flow (Fi) in the housing (2) while bypassing the first heat exchanger (5); and an air inlet duct (23) directing the inner air flow (Fi) in the housing (2) through the first heat exchanger (5). The invention also relates to heating, ventilation and / or air-conditioning equipment (1) for the passenger compartment of a motor vehicle, including: an air conditioning loop through which a coolant flows, including at least one compressor, a first expansion member, an outer heat exchanger and the first heat exchanger (5); and such a heating, ventilation and / or air-conditioning apparatus (1).

Description

technical field [0001] The technical field of the invention is heating and / or air conditioning installations for motor vehicles. Background technique [0002] Motor vehicles are usually equipped with an air conditioning loop or coolant fluid circuit in which a coolant fluid circulates. The air conditioning loop comprises in particular a compressor, an external heat exchanger, an expansion unit and an evaporator, through which a coolant fluid flows. [0003] Furthermore, in some special arrangements, the air conditioning loop also comprises an internal air cooler, in particular an internal condenser, through which the coolant fluid flows. In this configuration, the evaporator and interior air cooler are mounted within the housing of the heating, ventilation and / or air conditioning equipment typically housed in the passenger compartment of the vehicle. The enclosure is capable of directing the flow of interior air before it is distributed to the passenger compartment of the ...
