Problems solved by technology

Another issue that was raised was that the air jets located directly under the windshield and connected to said defroster openings should be supplied with warm air, and it is often ideal that the air from the air jets be blown directly to the passenger compartment. Humans have relatively fresh air, and ideally, the air is usually warmer at the legs and feet

Embodiment Construction

[0022] A preferred embodiment of a heating, ventilation and / or air conditioning device according to the invention will be described initially by referring to FIG. 1 . Said device comprises, in the usual manner, an evaporator 1 connected to a primary circuit corresponding to the air conditioning of the refrigerated air. From a refrigeration-technical point of view, a not-shown ventilation device is coupled downstream of the evaporator 1, said ventilation device bringing fresh air and / or moving air through the device.

[0023] From a refrigeration technical point of view, a heat exchanger 2 is connected in the lower section of said evaporator 1, downstream of which an optional electric heater is connected. The air flowing out of the evaporator 1 can pass directly above the heat exchanger 2 into a mixing zone 20 which, in the embodiment shown, is directly connected to the evaporator and is made in the above the heat exchanger. Thus the gas flowing out from the lower section of ...

Abstract

The invention concerns a heating, ventilating and / or air conditioning equipment which is particularly adapted for use in a motor vehicle, provided with a distributor casing wherein can be defined at least two air stream paths (16, 17) towards a mixing zone (20) and which is provided with at least two outlets (10, 11, 14, 15) one of which (11, 14, 15) at least can be supplied with air coming from the mixing zone (20), the apparatus comprising a device connected downstream of the mixing zone in terms of fluid mechanics, which reduces, more specifically excludes almost completely any reciprocal action of the air exiting from the mixing zone with the air which flows in a different direction forming, for example, each time two conduit-like passages (18, 19) providing an uncoupled crossing of air streams.

Description

technical field [0001] The invention relates to a heating, ventilation and / or air conditioning device, which is especially suitable for use in a motor vehicle. Background technique [0002] Such heating, ventilation and / or air-conditioning systems are usually equipped with a distribution box, in which at least two air flow paths can be formed, usually for hot air and for cold or fresh air, to a mixing zone. Hot air is generally produced by passing fresh air through a downstream heat exchanger, to which an optional electrical heating unit may be incorporated. If an air conditioner is provided, the cold or fresh air generally passes through an evaporator where it is cooled. In most of the currently available installations equipped with the air conditioner, the hot air also passes through the evaporator of the air conditioning circuit before passing through the heat exchanger. In the mixing area, it is attempted to control a desired temperature on the air side and / or heat exc...
