Definitions

  • the invention relates to an atmospheric refrigerant comprising at least one heat exchanger between at least one fluid, for example water, and a gas, for example atmospheric air, of the type comprising a battery of substantially parallel flexible exchanger tubes between them fixed at each of their ends in a tubular plate of a device for distributing and / or collecting said fluid, the latter circulating in the exchanger tubes while the q has 7 through the battery transversely with respect to said tubes.
  • the invention applies to atmospheric refrigerants of the “dry” type in which the fluid to be cooled is brought into indirect contact with atmospheric air via the wall of the tubes of the exchanger, to atmospheric refrigerants of the type "Mixed which comprise both at least one exchanger of the aforementioned type and at least one wet exchange body in which a liquid, which may or may not be the fluid circulating in the tubes of the exchanger, is brought into direct contact with atmospheric air, and to atmospheric refrigerants of the “hybrid” type in which the tubes of the exchanger of the aforementioned type are wetted externally by a liquid, which may or may not be the fluid circulating in the tubes of the exchanger.
  • the setting in motion of the air in these refrigerants is ensured either by natural draft, assisted or not by fans, or only by blower or suction fans.
  • the patent FR-A-2 180 683 describes a heat exchanger made up of flexible plastic tubes taking advantage of the possibility of using very large tubes, but which is still designed as a conventional battery of finned metal tubes, that is to say as a rigid parallelepiped assembly.
  • the patent FR-A-1 455 991 also describes an exchanger made of plastic tubes.
  • the exchanger is rectilinear and of circular section of the type of water-water exchangers and not of fluid-gas exchangers such as those used in atmospheric refrigerants.
  • the flexibility of the tubes is only exploited at the ends of the exchanger to group them compactly for the hydraulic connection.
  • the exchanger is straight and even rigidly contained in a metal sheath.
  • Patent application FR-A-2 362 358 describes exchangers with flexible plastic tubes of great lengths arranged horizontally and capable of marrying various contours of refrigerants, or even their periphery.
  • the tubes are stretched at the level of their braces where they are possibly forced to bend and form an angle.
  • the curvilinear contours of refrigerants can be approached by polygonal contours of the exchangers.
  • the flexibility of the tubes is used here to conform the shape of the exchanger to that of the refrigerant, contrary to what is provided in the first two patents mentioned above.
  • the very long length of the tubes and the high coefficient of expansion of the plastic material from which they are made mean that. these tubes undergo significant variations in length which it is necessary to absorb. This therefore results in a complication in the production of the exchangers.
  • patent CH-A-582866 describes a heat exchanger intended for air conditioning apparatus.
  • This exchanger comprises hollow fibers which are embedded at their ends in a hardened resin. These fibers show a certain deflection under the action of their own weight. However, these fibers do not hang freely.
  • US-A-3,854,523 further describes a heat exchanger comprising bundles of flexible tubes in the form of hairpins. These tubes are kept in their vertical position and do not hang freely either.
  • the object of the invention is to provide an atmospheric refrigerant comprising a heat exchanger which is of a simpler construction than the known flexible tube exchangers while allowing the flexibility property of the tubes to be used to produce configuration exchangers. very varied.
  • the invention ' relates to an atmospheric refrigerant comprising at least one heat exchanger between at least one fluid, for example water, and a gas, for example atmospheric air, comprising a battery of tubes flexible exchangers substantially parallel to each other fixed at each of their ends in a tubular plate of a device for distributing and / or collecting said fluid, the latter circulating in the exchanger tubes, while the gas passes through the coil transversely with respect to said tubes, characterized in that said exchanger tubes are only supported at their two ends and have a length greater than the distance separating said tubular plates and said tubular plates are oriented so that said exchanger tubes hang freely between said ends, under the effect of their own weight, having, in a vertical plane, a profile substantially in the form of part of chain.
  • This arrangement has the advantage of being very simple in construction compared to those of known exchangers, of making it possible to carry out very varied configurations of exchangers and, moreover, of solving by virtue of its design without the need for external means, the problem of thermal expansion of the tubes which, as indicated above, is particularly crucial when using, as is preferably the case in the present invention, plastic tubes.
  • FIG. 1 to 4 we see an atmospheric refrigerant "dry mechanical draw of rectangular shape comprising a chamber 1 delimited by two side walls 2 supported by a metal frame 3. on two sides of the refrigerant, and by two faces open 4 constituting air inlets on the other two sides of the refrigerant.
  • Bedroom 1. is topped by a roof 5 in the form of a pyramid trunk which ends in a circular ferrule 6 in which is mounted a fan 7 driven by a motor which has not been shown for clarity of the drawing.
  • Each exchanger 8 included a battery 8 of flexible tubes 10 made of a synthetic material parallel to each other which are tightly connected at their lower part in the opposite tubular plates 11 of a distributing water box 12 for supplying water or other liquid to be cooled which has the shape of a rectangular parallelepiped and which extends over the entire length of the refrigerant at equal distance from the two open faces 4 of air inlet and at a certain distance above the ground 14, a pipe 13 of liquid distribution leading to the water box.
  • the tubes 10 of each battery 9 extend upwards from the water box 12 and are tightly connected at their upper part in a tubular plate 15 of a respective water box 16 collecting the cooled liquid , which is evacuated from the water boxes 16 by evacuation pipes 17.
  • the collecting water boxes 16 extend parallel to the dispensing water box 12 at the top of the chamber 1 where they delimit the upper edge of the air inlets 4, and they are supported like the water dispenser 12 by the metal frame 3 which has only been shown schematically for clarity of the drawing.
  • the tubes 10 (Fig. 4) of the exchangers 8 are made of a synthetic material which is both flexible or flexible, resistant to relatively high operating temperatures, in particular as regards creep, and transmitting heat relatively well, such as certain organic polymers, for example polybutene or crosslinked polyethylene.
  • the diameter of the tubes is preferably relatively small to allow good heat exchange, for example from 5 to 20 mm, and they are arranged, considering the exchangers 8 in a vertical transverse plane as in Figure 1, in a series of layers parallels whose number may be, for example, from 8 to 40.
  • the tubes 10 are fixed in a sealed manner in the tubular plates 11 and 15 by suitable sealed fixing devices, such devices being notably described in patent applications FR-A-2,341,095 and FR-A-2,380,488 and in patent FR-A-1,425,666.
  • the tubes 10 hang freely between their fixing points in the tubular plates 11 and 15 and, to prevent them from touching, they are grouped in a number of bundles 18 including the tubes are joined from distance to distance by bracing devices 19, an exemplary embodiment of which is shown in more detail in FIG. 4.
  • This bracing device 19 consists of a number of strips 20 held tight against each other the others by means of a frame 21 and which are provided with notches delimiting two by two of the passages for the tubes 10.
  • bracing devices are also described in patents FR-A-2180683, FR-A-2336621, FR-A-2 304 048 and in patents US-A-3 422 884 and 4 036 289 Thanks to these bracing devices, regular air passages are provided between the tubes which, preferably, are staggered by means of a shift of the adjacent plies with respect to each other, so that these passages require the air to follow a winding path between the tubes.
  • the tubes 10 have a length greater than the distance separating the tubular plates 11 and 15 so as to present a curved profile in a vertical plane as shown in Figure 1.
  • this Figure is schematic and does not claim to reproduce exactly the actual curvature of the tubes, this mainly depending on their length.
  • the tubular plates 11 and 15 must be oriented so that, in the normal position of the tubes, the ends of the latter are oriented substantially perpendicular to the tubular plates of the lower and upper water boxes, which are offset horizontally with respect to each other.
  • the liquid to be cooled for example water
  • the liquid to be cooled is brought by pumping means (not shown) to the dispensing water box 12 by the supply line 13.
  • the liquid is distributed in the tubes 10 of the two exchangers 8 and flows towards the collecting water boxes 16.
  • the liquid is cooled by atmospheric air which enters the refrigerant through the air inlets 4 and passes through the batteries 9 in the directions indicated by the arrows F in FIG. 1.
  • the air heated and sucked in by the fan 7 is then discharged into the atmosphere through the shell 6.
  • the side walls 2 stop at a certain distance above the ground 14, and more precisely at the height of the water dispenser 12, which saves two air inlets side to improve the penetration of atmospheric air into the refrigerant.
  • the side walls 2 can extend to the ground 14.
  • FIG. 5 differs from that of Figures 1 to 3 in that it comprises a single exchanger 108, the lower water box being omitted and the tubes of the exchanger 108 extending from one of the upper water boxes 116a, which constitutes a supplied dispensing water box by a supply line 117a, to the other water box 116b, which constitutes a collecting water box as in the previous example and is placed at the same height as the water box 116a.
  • the tubes of the exchanger 108 have a length substantially double that of the exchangers 8 and hang freely between the water boxes 116a and 116b having a profile in the form of a chain.
  • FIGS. 6 and 7 represent a mixed refrigerant which differs essentially from the refrigerant of FIGS. 1 to 3 in that it comprises two “cross-current wet” exchange bodies 222 each mounted in front of a respective “dry” heat exchanger 208 so that each atmospheric air flow passes in series through the wet exchange body 222 and the exchanger 208.
  • the collecting water boxes 216 comprise several discharge ducts 217a instead of one in the case of the refrigerant of the Figures 1 to 3, and these conduits 217a function as overflows which pour the liquid having passed through the exchangers 208 into two tanks 223 adjacent respectively to the two water boxes 216.
  • the tanks 223 are provided in their bottom with dispersing nozzles through which the partially cooled liquid in the exchangers 208 is poured over the associated exchange body 222.
  • the wet exchange bodies can be either of the type in which the liquid flows in the form of films thin as described for example in patents FR-A-1 140 551 and 2183704, or of the splash type as described in patent US-A-3751 017.
  • Under each exchange body 222 is arranged a basin 224 intended to collect the cooled liquid which flows from the exchange body and which is then evacuated from each basin by an evacuation pipe 225.
  • drop separator 226 Between each wet exchange body 222 and the associated dry exchanger 208 is disposed a drop separator 226.
  • drop separators are perfectly conventional and examples are given in particular in patents GB-A-1 347 648, US -A-3 925 523, US-A-3 804 389, US-A-4 052 491, FR-A-2 316 570, FR-A-2 331 762 and in patent application DE-A-2602485.
  • drop separators are necessary only to reduce the vesicular entrainments of the refrigerant, but also to ensure good efficiency for the dry exchangers from the first layers of tubes, which can therefore heat the air to constant absolute humidity, therefore to decreasing relative humidity, useful effect sought by the dry heat exchanger in mixed refrigerants in order to reduce the plume, these first layers should therefore not be used to evaporate the liquid water from the vesicular entrainments. the water vapor pressure.
  • the side walls 204 extend to the ground due to the presence of the wet exchange bodies in which the atmospheric air must circulate in cross currents relative to the liquid.
  • the device for bracing the tubes of the exchangers 208 is different from that of the exchangers 8.
  • This device consists of split rings or discs 227, for example made of plastic, which are mounted on the tubes 210 and whose radial width determines the spacing between the tubes.
  • the tubes 210 can be joined together by bundles by means of any suitable links (not shown).
  • any type of suitable bracing device other than those shown in FIGS. 4 and 8, for example protrusions on the tubes, can be used to maintain the spacing between the tubes of the exchanger according to the invention.
  • the operation of the refrigerant of FIGS. 6 and 7 is the conventional operation of a mixed refrigerant with series circulation of the liquid to be cooled and atmospheric air and, as it moreover clearly results from the above description, it will not be described in more detail.
  • Figs. 9 and 10 represent another type of "mixed refrigerant in which the liquid to be cooled also circulates in series in the" dry "exchanger and in the" wet "exchanger but where the two exchangers are traversed by parallel air flows which do not only mix after passing through the two exchangers.
  • the same reference numbers have been used as in the preceding figures to designate the analogous parts but by assigning them the figure of hundreds 3 instead of the figure of hundreds 2 and the figure of hundreds 1 in the examples of FIGS. 6 and 7 on the one hand, and from FIG. 5 on the other hand.
  • the liquid supply to the exchangers 308 is carried out from above by means of the pipes 317 which are connected to the upper water boxes 316 by a series of parallel pipes 317 '.
  • the partially cooled liquid in each of the two exchangers 308, which are arranged on each side of the refrigerant above the wet exchanger 322, is collected in the lower water boxes 312 which distribute it to respective supply tanks 323 themselves supplying the distribution network 328 of the countercurrent wet exchange body 322.
  • FIGS. 9 and 10 The operation of the refrigerant of FIGS. 9 and 10 is similar to that of mixed refrigerants with parallel air flows. It will simply be noted that, as a variant, the circulation of the liquid in the dry exchangers 308 and wet 322 could be done in parallel instead of occurring in series and that, moreover, the refrigerant, instead of being rectangular, could be circular.
  • Fig. 9 remains valid in this case but is supposed to represent a single upper water box 316 of circular shape and a single lower water box 312 also of circular shape.
  • Figs. 11 and 12 show the application to a hyperbolic type cooling tower with natural draft of the pendant tube exchanger according to the invention.
  • the tower comprises a shell 429 made of thin concrete veil and a network 430 of cross-shaped beams supporting the shell by means of a circular lintel beam 431 to define a peripheral air inlet 404.
  • the upper supply water box 416 which is continuous or consists of a succession of short rectilinear elements aligned circularly, supplying the battery 409 with flexible plastic tubes whose lower ends are connected to the lower circular water box 412, the overall diameter of which is less than that of water box 416.
  • This difference between these diameters leads to a difference between the spacings of the tubes: at the lower water box, the spacing in the tangential direction is smaller. This can possibly be compensated, having regard to the passage of air, by an increase in the spacing in the radial direction, or even by the splitting of plies of tubes in a staggered arrangement.
  • the diameters of the current towers at the lintels being very large of the order of 100 to 200 m
  • the difference in the overall diameters of the lower and upper water boxes is relatively low, of the order of a few meters to about twenty meters at most, and does not pose difficult problems relating to the variation in spacing of the tubes.
  • FIG. 13 also shows a hyperbolic type cooling tower with natural draft, but where the battery 509 of plastic tubes takes a centrifugal direction from the lintel 531, because the lower water box 512 has a diameter greater than that of the bottom edge of air inlet opening 504.
  • the slightly larger spacing of the tubes compared to that existing at the upper water box 516 can be taken advantage of to compensate for the tendency to decrease the air flow. between the lintel and the ground since, in fact, the air pressure losses on passing through the exchanger increase from top to bottom if the radial pitch of the exchanger is constant.
  • the battery 409 or 509 consists of several layers of tubes, each defining a surface of revolution of curvilinear profile.
  • the internal fluid of the dry exchangers of mixed wet-dry refrigerants could be different from that of wet exchangers.
  • the fluid supply circuits fluid for the dry exchanger; water or aqueous solution for the wet exchanger
  • the setting in motion of the air of the refrigerants concerned can take place either by fans, sucking or blowing air through the exchangers, or by a natural draft chimney, assisted or not by fans.
  • the wet exchange bodies can be of all known types, particularly against the current, or with cross currents, of the film-flow or splash-type, or combined.
  • the wet and dry exchangers can be mounted in parallel or in series in the air flow and, for the latter case, the dry exchanger can be upstream or downstream of the wet exchanger in this air flow.
  • the exchanger according to the invention could also be designed, no longer only as a dry exchanger, but as a hydride exchanger as described in European patent application No. EP-A-10118 (78400144.8).
