Definitions
- the present invention generally relates to a heating-air conditioning installation and in particular a heating-air conditioning installation for a vehicle.
- a heating-air conditioning installation comprises an evaporator, a heating body and a blower, in order to pass the air successively through the evaporator and the heating body, so that it is distributed in the desired places, after have been treated by different air outlet channels.
- a heating-air conditioning installation comprises an evaporator, a heating body and a blower, in order to pass the air successively through the evaporator and the heating body, so that it is distributed in the desired places, after have been treated by different air outlet channels.
- Another general appearance wish is to be able to supply air to the passenger compartment of the vehicle while retaining a minimum blowing power, in order to be able for example to maintain a pleasant temperature. in the passenger compartment when the vehicle engine is stopped, or at least to be able to adjust it at will.
- the objective of the present invention is therefore to provide a heating-air conditioning installation which takes account of the above wishes and which requires as little additional building volume as possible, or even no additional building volume.
- the invention proposes a heating-air conditioning installation, in particular for a vehicle, which has an evaporator and a heating body, a fan as well as various air outlet channels, at the at least one air flow control means being placed next to the evaporator, from the point of view of fluid technology, in order to be able to close and open an air path bypassing the evaporator and opening into a air outlet, which can be traversed by the air stream at least in sections in another direction if the air flow control means is closed.
- the invention proposes to use a space inside the heating-air conditioning installation in a bivalent manner, that is to say on the one hand, in the conventional sense of a heating installation - air conditioning and on the other hand as a channel for air which does not pass through one evaporator.
- This configuration makes it possible to provide an air path which does not pass through the evaporator, practically without additional bulk, and thus makes it possible to guide through it air which has been supplied with only minimal blowing power.
- the installation according to the invention can also be used in such a way that the air passes simultaneously through the evaporator and in front of it.
- the air path bypassing the evaporator which can be released by the air flow control means, can be traversed at least in sections, by air essentially perpendicular thereto , when the air flow control means is closed.
- air could, in the usual operation of a heating-air conditioning installation, pass successively through an evaporator and then a heating body, in order to then be deflected essentially upwards, towards diffusers that can power the windshield. If we now allow fresh air to pass essentially horizontally through this channel extending upwards, in order for example to lead to diffusers in the dashboard, this space is precisely used accordingly in a bivalent manner.
- the air path which can be released by the air flow control means, bypassing the evaporator can, when the air flow control means is closed, be traversed by air essentially in the opposite direction to that existing when the air flow control means is open.
- a channel which, during normal operation, serves to convey air upwards can for example be used to guide untreated air or at least bypassing the evaporator, to a lower section of the vehicle.
- the air flow control means may, in the closed position, be part of the wall of the channel portion involved.
- the air flow control means is provided above the evaporator, and in particular near one of the air outlet channels. Thanks to this configuration, it is possible to adjust the shortest path from the blower to the outlet, so that the flow and / or pressure losses are minimized at least for part of the air passing through. this way.
- the air path which can be released by the air flow control means, and which bypasses the evaporator can pass directly into at least one air outlet channel, in particular without go through an air handling device.
- the heating-air conditioning installation according to the invention can at least contain another means of controlling the air flow, which can free and block an air passage towards a space between one evaporator and the heating body. Thanks to this means of controlling the additional air flow, other different air channels can be made available for the air which does not pass through the evaporator. For example, two air streams, namely one passing in front of the evaporator, respectively through the evaporator, can be mixed, from the point of view of fluid technology, behind one evaporator, in order to regulate the air guided to the different diffusers, in temperature and / or humidity, or however to influence it.
- the air path which can be released by the air flow control means, and bypassing the evaporator extends in particular through the air passage released by the other means air flow control, between one evaporator and the heating body. Guiding the air bypassing the evaporator between the evaporator and the heating body may be advantageous in that there is usually no resistance to flow in this space, for example by other elements of air guiding or the like, and above all this space is suitable for preventing, during normal heating / air conditioning operation, drops of moisture forming on the evaporator from affecting the heating element until to damage it.
- the air in the air path which can be released by the air flow control means, and bypassing the evaporator can pass in front of the evaporator and / or the heating body essentially tangentially, so that any residual cooling or heating that may be present can be resumed, without resulting in a loss of pressure by flow through an air treatment device.
- the air path which can be released by the air flow control means, and bypassing the evaporator extends at least in one direction through at least one heating body which is essentially opposite to the direction in which the air leaves the evaporator.
- the air path which can be released by the air flow control means, and bypassing the evaporator extends at least in one direction through at least one heating body which is essentially opposite to the direction in which the air leaves the evaporator.
- the heating-air conditioning installation according to the invention allows an air supply inside the passenger compartment with minimum power requirements at the blower, without requiring a volume. additional construction.
- An advantageous parallel phenomenon is that the heating-air conditioning installation according to the invention also allows humidity regulation in the interior of the passenger compartment, since the air which has not passed through regularly exhibits humidity. higher relative. So for example in normal operation of the heating-air conditioning system, if a channel, for example for supplying the bottom part, is not required, this channel can be used as an air channel for air which bypasses the evaporator and can thus bring moisture inside the passenger compartment.
- the heating-air conditioning system according to the invention can also be used as a ventilation and / or auxiliary heating device as in a conventional heating-air conditioning operation, in which part of the air can arrive in the form untreated, but at least without passage through one evaporator, inside the cabin.
- FIGS 1 to 5 illustrate in schematic sectional view a heating-air conditioning installation as a preferred embodiment of the invention, different air paths for the air bypassing the evaporator being indicated in the different figures.
- FIG. 1 illustrates in schematic section a heating-air conditioning installation which can be supplied with air by means of a blower not shown.
- the illustrated heating-air conditioning installation comprises, in a conventional manner, an evaporator 10, a heating body 12 and an electric heating device 14, which is in the illustrated embodiment of the type known as PTC (positive temperature coefficient) .
- the installation further comprises various air control means, which can be made entirely or partially in the form of mixing valves and can also be, in any intermediate positions, between an open position and a closed position, in the embodiment illustrated in the form of butterfly valves and of a so-called shell valve 8, so that various air outlet channels 2, 4, 6 can be supplied in adjustable air.
- the air outlet channel 2 is used to supply nozzles which open directly at the level of the windshield, in order to be able to prevent, for example, the formation of mist on the latter.
- the air outlet channel 4 is connected to diffusers not illustrated on the dashboard, while an air outlet channel 6 extends towards the inside of the plane of the drawing to lead, in front of the housing of the installation of heating-air conditioning, to diffusers in the foot region or also to diffusers arranged laterally.
- the air outlet channel 6 should be considered as a channel whose supply can be stopped most easily without significantly affecting passenger comfort.
- the air outlet channel 6 is used to supply the bottom part, in which case it would be possible to use it only when necessary, it that is to say when the passengers are at the bottom of the vehicle.
- the illustrated embodiment unlike heating-air conditioning systems known up to now, has an air flow control means 20 which makes it possible, in the closed position, to supply the air outlet channel 6 in the usual way, in that the air flow control element 20 defines a wall of the space connected to it.
- an air flow control means 30 which allows passage to the space between the evaporator 10 and the body heater 12, as well as an air flow control means 40, which can fulfill various functions for various operating modes, namely on the one hand, when the air flow control element 20 is closed, the air deflection that went through 1 evaporator 10 and the heating body 12, to the air outlet channel 2 and / or 6, while the air flow control means 40, when the air flow control means 20 is open, used to allow the air which has passed in front of the evaporator 10 to pass through the heating body 12.
- the air channel A may for example be an auxiliary operating mode of the heating-air conditioning installation, in which one would like to bring the residual heat from the heating body 12 in the interior of the passenger compartment, for example via the air outlet channel 4.
- the air flow control means 20 is in the open position , so that the portion of .. pipe lying behind in normal operation is traversed in reverse by the current, in order to allow the air to reach the air flow control means 40 which directs the air through the heating body 12, after which for a corresponding positioning of the shell valve 8, for example in the form of a mixing air valve, the air can pass through the air outlet channel 4.
- part of this air flow could also leak through the air outlet channel 2 for a corresponding position of the air flow control means, so that even for a low air flow, that is to say using a power of weak blowing, one can obtain a temperature gradation in the interior of the passenger compartment.
- the air passes, instead of the heat exchanger for heater 12, in the additional heater which could be for example an electric heater or also some other additional heater. In this way, one can realize, as illustrated, an auxiliary heating independent of the engine.
- the air path bypassing the evaporator which is released by the air flow control means 20, extends between the evaporator 10 and the heating body 12, the additional air flow control means 30 being arranged for this purpose in the open position.
- This configuration efficiently uses a space between the evaporator 10 and the heating body 12, the direction of flow indicated being essentially perpendicular to the direction of flow usually existing. After the air has thus passed against the evaporator 10, through the air flow control means 20 and between the evaporator 10 and the heat exchanger for heating 12, it can reach, passing through the shell valve 8, to the air outlet channel 4.
- FIG. 4 illustrates another configuration of air channel possible in the form of a bypass with respect to all the air treatment devices, that is to say the evaporator 10, the heat exchanger for heating 12 and the electric heating device 14.
- the air channel D thus extends above these air treatment devices and thus opens directly into the passenger compartment of the vehicle to supply fresh air and / or moisture.
- this configuration of the air channel D could also end directly in the air outlet channel 2.
- FIG. 5 illustrates yet another possible configuration for an air channel, which bypasses the evaporator 10, but nevertheless passes through the heat exchanger for heating 12 and / or the electric heating device 14.
- This channel d air allows, for example in normal operation, provided that the air outlet opening 6 does not have to be supplied, to bring, by means of air conditioning and possibly subsequently heated, humidity to the interior of the passenger compartment, in particular in the event of very low outside temperatures, for which the air humidity is naturally low.
