no. 1 example

[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 device (1) for a vehicle passenger compartment, comprising a housing (2) comprising a first air inlet (3) and a second air inlet (4), and An internal air flow (Fi) is guided from a first air inlet (3) and / or a second air inlet (4), wherein the housing (2) accommodates at least a first heat exchanger (5). The housing (2) comprises air flow channels (24) guiding the internal air flow (Fi) in the housing (2) while bypassing the first heat exchanger (5), and guiding the internal air flow in the housing (2) (Fi) through the air inlet duct (23) of the first heat exchanger (5). The invention also relates to a heating, ventilation and / or air conditioning installation (1) for a passenger compartment of a motor vehicle, comprising an air conditioning loop through which a coolant fluid flows and comprising at least one compressor , the first expansion member, the external heat exchanger and the first heat exchanger (5); and such heating, ventilation and / or air conditioning equipment (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 ...
