- the document FR 2 900 723 describes such an air conditioning device comprising an evaporator / absorber assembly composed of porous plates in which the fluids are dispersed, some of which are traversed by the refrigerant fluid to be evaporated, in this case water, and others by the absorbing fluid, in this case a solution of Lithium Bromide.
- Absorption air conditioning devices comprising two fluid circuits, one of absorbent fluid and the other of refrigerant fluid, require the presence of separate fluid recovery tanks for each of these circuits. These reservoirs occupy an important place, and the fluids with which they are filled weigh heavily. Thus, the volume and weight of these existing devices remain relatively large, and it is necessary to reduce them to effectively adapt such a system in the reduced space of a vehicle.
- the pumps circulating liquids in the circuits must be permanently supplied with liquid to ensure their proper operation and reliability.
- the absorption air conditioning device requiring a supply of heat, usually from the engine of the vehicle, to perform the desorption, this desorption can not be done effectively before the engine is hot.
- the operation of the air-conditioning device for absorption during the first minutes of operation of the vehicle is therefore done using the absorbent fluid reserves and those of coolant, which are not renewed immediately.
- the amounts of absorbent fluid and refrigerant in reserve must be sufficient to ensure the correct operation of the air conditioning device during this period during which the desorber does not work.
- the object of the present invention is therefore to provide an air conditioning device adapted to motor vehicles, which is improved in its operation with respect to known air conditioning or absorption cooling devices of the prior art.
- the object of the present invention is to provide an absorption air conditioning device that allows to offer the same performance with a reduced volume compared to the devices of the prior art.
- Another object of the present invention is to provide such an absorption air conditioning device, which is simple in design and whose implementation requires inexpensive technological means.
- the invention also aims to provide such an absorption air conditioning device with good reliability, with a simple and effective actuator control system.
- an air conditioning device in particular for a motor vehicle, comprising a liquid recovery tank, characterized in that said tank is composed of two compartments in communicating with each other by a first passage located in the lower part of the tank, a first of said compartments, said main compartment, having a liquid inlet opening and a liquid outlet opening located lower than the liquid inlet opening, and the second compartment, said auxiliary compartment, comprising discharge means for discharging at least a portion of the liquid of the auxiliary compartment to the main compartment through the first passage.
- the discharge means allow an increase in the pressure in the auxiliary compartment
- the discharge means are constituted by means for heating the liquid contained in the auxiliary compartment, able to cause evaporation of a portion of this liquid so that the evaporated gas present in the auxiliary compartment exerts pressure on the liquid. delivery of the liquid to the main compartment.
- the two compartments are also in communication with each other by a second passage passing a low gas flow, located in the upper part of said tank.
- the main compartment has a funnel-shaped constriction around the outlet opening.
- This shape allows an acceleration of the liquid flow to the outlet opening of the tank.
- the reservoir comprises internal fins preventing the vortex movement of the liquid contained therein.
- These fins may be shaped or inclined so as to avoid the cavitation at the inlet of the centrifugal type pump, by using the gravity and the arrival speed of the fluid to initiate the rotary movement necessary for the operation of this type of pump.
- this air conditioning device is an air conditioning device absorption.
- said secondary compartment is in communication with an evaporator / absorber assembly of said absorption air conditioning device by a passage passing a small gas flow, located in the upper part of said secondary compartment.
- the present invention also relates to a motor vehicle, which comprises an improved air conditioning device according to that described above.
- FIG. 1 shows schematically the principle of operation of an air conditioning device by absorption
- FIG. 2 shows, schematically, the functional circuit of an air conditioning device by absorption
- FIG. 3 is a perspective view of an evaporator / absorber assembly of an absorption air conditioning device according to one embodiment of the invention
- FIG. 4 is a section of a liquid recovery tank, or tank, of an air conditioning device according to an embodiment of the invention.
- FIGS. 5 and 6 are sections of a liquid recovery tank, or reservoir, of a air conditioning device according to another embodiment of the invention.
- An absorption air-conditioning device implements a double fluid circuit, one carrying a cooling fluid, for example water, and the other an absorbing fluid.
- a cooling fluid for example water
- an absorbing fluid for example a lithium bromide salt solution (LiBr).
- Figure 1 shows, schematically, the constituent elements and the operating principle of an air conditioning device by absorption. It comprises an element in which the desorption is carried out, designated “desorber” 100 in the rest of the text, a condenser 200, an evaporator 300 and an absorber 400.
- the desorber 100 and the absorber 400 are filled with a mixture of at least two miscible substances formed by the coolant and the absorbent fluid. This mixture is combined in absorber 400, wherein the absorbent fluid absorbs refrigerant under vapor phase.
- the refrigerating fluid and the absorbing fluid have sufficiently different evaporating pressures so that, when the mixture is heated in the desorber 100, the refrigerant, more volatile, evaporates, allowing the separation of the two fluids.
- the heat necessary for this separation can advantageously be provided to the desorber by the engine coolant of the vehicle.
- the refrigerant in the form of steam is then fed through the pipe 120 into the condenser 200 to be condensed by the cooling action of the outside air (cooling contribution schematically illustrated by the arrow B).
- the coolant in the liquid phase is then fed through the pipe 210 to the evaporator 300.
- the cold produced during the evaporation of this refrigerant fluid is transmitted to the cabin of the vehicle (not shown), as schematically illustrated by the arrow C.
- a heater 320 which is connected to a pump 310 and to the evaporator 300 via the lines 311 and 313.
- the refrigerant vapor exiting the evaporator 300 is fed into the absorber 400 through the conduit 21 which is formed by the envelope of the absorber / evaporator assembly.
- the absorbent fluid which has been cooled by external air in the absorbent solution circuit (cooling supply schematically illustrated by the arrow D), then absorbs this refrigerant vapor to reform the mixture.
- the absorbent solution circuit is formed by a radiator 420, which is connected to the pump 410 and the absorber 400 through the pipes 416, 417 and 419.
- the absorber 400 is connected to the desorber 100 via the pipes 414, 415 and 416 .
- Figure 2 shows the functional circuit of an absorption air conditioning to which the present invention can be applied.
- it is an absorption machine that uses the LiBr-water pair (lithium bromide as absorbent fluid and water as coolant).
- references 100 and 200 respectively denote the desorber and the coolant condenser.
- References 320 and 420 respectively denote the coolant heater and the radiator of the absorbent fluid.
- References 310 and 410 respectively designate the refrigerant circuit pump and the absorbent fluid circuit pump.
- References 350 and 450 respectively designate the reserve of refrigerant fluid and the reservoir of absorbent fluid.
- References 62 and 63 denote check valves, and reference numeral 120 denotes the pipe bringing water vapor from desorber 100 to condenser 200.
- Reference 500 denotes an assembly that combines the absorber and the evaporator of the air-conditioning device by absorption.
- this evaporator / absorber assembly traversed by a flow of refrigerant fluid and an absorbent fluid flow, a part of the refrigerant is evaporated, and this endothermic evaporation reaction has the effect of cooling the flow of refrigerant remaining.
- the vapor produced is directly absorbed by the flow of absorbent fluid.
- FIG. 3 represents a perspective view of certain elements of such an evaporator / absorber assembly, showing two distinct circuits, one traversed with refrigerant fluid and exerting the evaporator function, and the other traversed with absorbent fluid and exerting the absorber function.
- the circuit traversed by the cooling fluid comprises a refrigerant supply pipe 301, supplying a fluid to a refrigerant distribution box 302 which distributes the refrigerant in a plurality of evaporating frames 330 extending vertically and parallel to each other.
- the refrigerant circulates, essentially by gravity, in a dispersion plate (not shown in FIG. 3), and a portion of the fluid evaporates.
- the circuit traversed by the absorbing fluid is very similar to the circuit traversed by the refrigerant fluid. It thus comprises a feed pipe in Absorbent fluid 401, supplying fluid to an absorbent fluid distribution box 402 which distributes the absorbent fluid in a plurality of absorption frames 430 extending vertically parallel to each other and parallel to the evaporating frames 330 with which they are alternated.
- the absorbent fluid circulates, essentially by gravity, in a dispersion plate (not shown in Figure 3) of the absorption frame 430, and absorbs refrigerant vapors. It exits the absorption frame 430 through its fluid outlet opening 432, and arrives in the absorbent fluid reservoir 450.
- the evaporator / absorber assembly shown in FIG. 3 is incorporated in a sealed housing (not shown) avoiding gas exchange with the outside.
- the coolant reservoir 350 and the absorbent fluid reservoir 450 serve to store the fluids, in liquid form, before they are returned to the circuit by the pumps located downstream of the tanks. They allow enough fluid to fill each of the two circuits during system operation.
- the absorbent fluid absorbs refrigerant vapor
- its volume increases while the refrigerant volume decreases almost the same amount.
- the difference in volume can thus be relatively large, for example during the start-up phase of the air conditioning.
- the absorbent fluid is lightly charged with refrigerant, its volume decreases while its salt concentration increases. The absorption reaction is then more efficient. Depending on its salt concentration, this absorbent fluid is more or less sensitive to freezing or crystallization, the solutions too or not enough concentrated being more sensitive.
- a saline solution of LiBr at 10% of mass concentration of LiBr freezes at a temperature of -5 ° C
- the same salt solution at 50% concentration freezes at a temperature of -42 ° C
- the saline solution at 54% concentration freezes at a temperature of -16 ° C
- saline solution at 62% concentration freezes at + 28 ° C.
- the fluids must be present in the circuits in sufficient quantity so that the salt concentration of the saline solution can be kept within limits allowing the correct operation, whatever the phase of operation of the air conditioning device (start up, operation at maximum power , etc.).
- the tanks can store at least a portion of the fluid when the air conditioning device is stopped. Indeed, if the vehicle is stopped under low temperature conditions, there is a risk that the fluids freeze and damage or block the circuits. Since the tanks can be easily isolated from the cold, they can protect the fluids contained in it from freezing.
- volume of tanks and fluids stored must remain relatively small compared to the total volume of fluids present in the circuit, to avoid congestion and excessive weight of the air conditioning device.
- FIG. 4 is a sectional view of a reservoir for recovering a liquid according to a possible embodiment of the invention.
- This tank 1 comprises in the upper part an inlet opening 11, through which the liquids enter the tank, and in the lower part an outlet opening 12 through which the liquids leave the tank.
- a pump 2 is mounted in the outlet pipe, close to the outlet opening 12, to send into the circuit the liquids contained in the tank 1.
- This pump 2 in the example shown, can be of the centrifugal type and comprises a motor 21 and a wheel
- This pump 22 (shown in phantom) rotating about the axis 23, which draws the liquid through the outlet opening 12 of the tank 1 and delivers it into the pipe 24.
- the axis of rotation 23 of this pump is placed vertically to improve its effectiveness under low pressure and / or low liquid height.
- This pump can also, to improve this efficiency, include a device accelerating the fluid, such as a propeller.
- the inlet opening 11 of the tank 1 is equipped with a float valve 4 intended to prevent an overflow of liquid, especially during the shutdown of the air conditioning.
- the tank 1 is divided into two compartments, a main compartment 15, on which are open the inlet opening and the outlet opening, and an annex compartment 16 surrounding the main compartment 15.
- the main compartment 15 advantageously has a narrower cross section at the bottom than at the top, according to the model of a funnel. This profile makes it possible to orient preferentially the flow of liquid penetrating into the reservoir through the inlet opening 11 towards the outlet opening 12, and towards the axis of rotation.
- this form of compartment 15 makes it possible to increase the vertical speed of the liquid in the tank, thanks to the gravity, which has the effect of increasing the performance of the pump 2. , the increase in the speed of arrival of the liquid on the pump increases the dynamic pressure of the liquid, which reduces the risk of occurrence of cavitation phenomenon at this level. It should be noted that such a reservoir having two compartments, one of which has a funnel shape for accelerating the flow of liquid to the outlet opening can be advantageously implemented in an air conditioning independently of the other characteristics of the reservoir shown in Figure 4.
- the annex compartment 16 is connected to the main compartment 15 by passages 18 placed at the bottom of the wall 17 separating these two compartments. Furthermore, a restricted passage 19, located at the top of this wall allows the passage of a small flow of gas between the annex compartment 16 and the main compartment 15.
- This restricted passage 19 may be constituted by a calibrated hole, so generating a gas flow rate of the order of 10 liters per hour. According to another possible embodiment, this restricted passage 19 may consist of a material porous to gas and not to liquids, such as a non-woven polypropylene or polyethylene film.
- the secondary compartment may be in communication with an evaporator / absorber assembly of the absorption air conditioning device via a restricted passage allowing a low gas flow rate to pass through, located in the upper part of the secondary compartment.
- the level of liquid is normally identical in the two compartments of the tank 11, according to the principle of communicating vessels. However, it is important that the level of liquid above the pump is permanently sufficient to ensure proper operation of the fluid circuit and the pump, in particular to supply the pump without gas being sent into the pipes.
- a heat source 161 which may for example be an electrical resistance, is provided in the annex tank 16.
- the heat source 161 warms the liquid contained in the auxiliary compartment 16 so as to cause rapid formation of vapor in this annex compartment 16.
- the quantity of steam produced is too great to pass through. the main compartment through the restricted passage 19, the pressure of the gases in the annex compartment 16 increases, which causes a discharge of the liquid to the main compartment 15 through the passages 18, and therefore an increase in the level of liquid in the compartment 15.
- the heat source 161 stops working, which causes a cooling of the liquid contained in the annex compartment 16.
- the vapor contained in this compartment 16 then condenses by reducing the pressure , which is also reduced by the gradual passage of gas through the restricted opening 19.
- the liquid level again quickly becomes identical in the main compartment 15 and in the annex compartment 16.
- the restricted opening 19 makes it possible to prevent this regulation system from being disturbed by the accidental presence of incondensable gases (such as air) in the annex compartment 16.
- FIGS. 5 and 6 show the implementation of this level control system in a tank 5 of a type different from that shown in FIG. 4.
- This tank has a main compartment 55 into which an inlet opening opens. liquid 51 and a liquid outlet opening 52. It also has an auxiliary compartment 56 open on the main compartment 55 by a passage 58 located at the bottom of the wall 57 separating the compartments, and a restricted passage 59 at the top of this wall 57.
- the sub-compartment 56 comprises a heat source 561 such as an electrical resistance.
- a heat source 561 such as an electrical resistance.
- the fluid level is the same in both compartments.
- the heat source is active, as shown in Figure 6, it warms the fluid present in the auxiliary compartment, which evaporates a part of it.
- the gases produced cause an overpressure in the auxiliary compartment 56, which has the effect of discharging the fluid in the main compartment 55.
- the fluid level in this main compartment 55 therefore increases.
- the tank 5 is equipped with a float valve 4.
- the level control system may, however, advantageously be implemented in an air conditioning system tank independently of this valve.
- fins may extend vertically in the tank 1 so as to prevent the liquids from rotating, or swirling, in it.
- Such fins may be present both in the main compartment and in the auxiliary compartment of the tank, and may contribute to the stiffening thereof.
- the present invention offers many advantages, among which the following advantages:
