Les tours de refroidissement ou les refroidisseurs de fluide à circuit fermé fonctionnent de la même façon que leurs équivalents à circuit ouvert , à la différence qu'ils dissipent la charge de chaleur du fluide dans l'air ambiant via une batterie d'échange de chaleur . Cette disposition isole le fluide du process de l’air extérieur, afin d'assurer la propreté de l'air et de lui éviter toute pollution au sein d'un circuit fermé, et crée deux circuits de fluide séparés :

• un circuit externe , dans lequel de l' eau pulvérisée circule sur la batterie et se mélange à l'air extérieur ;
• un circuit interne , dans lequel le fluide du process circule au sein de la batterie.

Au cours du processus de refroidissement évaporatif , la chaleur passe du circuit interne vers l’eau de pulvérisation à travers la batterie, puis dans l’atmosphère par évaporation d’une partie de l’eau.

Les principaux avantages des refroidisseurs de fluide sont :

• Circuit de refroidissement non pollué
• Fonctionnement à sec en hiver
• Maintenance réduite du système
• Coûts globaux inférieurs grâce aux économies réalisées tout au long de l'année sur la maintenance, l'eau, l'énergie et le traitement de l'eau

Cooling towers

Cooling towers are essential components of many air-conditioning and cooling systems. They work by dissipating the heat generated by industrial processes or air conditioning systems using a variety of cooling media. In this comprehensive guide, we'll explore in detail everything you need to know about cooling towers, including how they work, the different types, maintenance and repair, as well as tips for extending their service life.

What is a cooling tower?

Operation and basic principles.

A cooling tower is a cooling system that uses the evaporation of water to extract heat from the hot air. The hot water from the condenser is sprayed on the fans of the tower where it is cooled by evaporation. This process allows you to cool water which can then be used to cool the equipment or process that requires an effective cooling.

Differences between a tower and other cooling systems

Cooling towers are distinguished from other cooling systems such as heat exchangers, by their ability to cool large quantities of water in a relatively short period of time. In contrast to the cooling unit (individual, a cooling tower can be used to cool multiple pieces of equipment or processes simultaneously, which makes it an effective choice for industrial applications.

Cooling technologies used in towers

The cooling towers use different technologies to cool the water including evaporative cooling systems and cooling towers. Axial fans are commonly used to ensure adequate airflow through the tower, which facilitates the process of cooling. These technologies help to optimize the performance of cooling towers in ensuring an efficient cooling, and economic.

Cooling tower types

Closed-circuit cooling towers.

Closed-circuit cooling towers operate by cooling water within a closed circuit, minimizing water losses through evaporation. These towers are more efficient in terms of water consumption, and are often used in applications where water conservation is essential.

Open circuit cooling towers

The towers cooling open circuit use the water from an external source to cool the equipment. The water, once used, is released into the environment, which may lead to problems of water quality due to the salts contained in it. However, these towers are often more simple and less costly to install than the towers closed circuit.

Comparing the advantages and disadvantages of different tower types

Closed-circuit cooling towers offer greater energy efficiency and a reduced environmental footprint, while open-circuit towers are easier to maintain and less costly. The choice of tower type will depend on the specific needs of each application in terms of water consumption, operating costs and durability.

Cooling tower maintenance

Cooling tower repair, signs indicating the need for repair.

Signs of cooling tower malfunction include water leaks, reduced cooling efficiency, unusual noises or temperature fluctuations. If you observe these signs, it's advisable to have the tower professionally inspected and repaired to avoid further damage.

Common repair techniques for cooling towers

The current repairs of cooling towers generally consist of replacing defective components such as fans, heat exchangers or pumping systems. The repair techniques vary according to the nature of the problem and may require the intervention of specialized technicians.

Average cost of repairs and component replacement

The cost of cooling tower repairs depends on the severity of the problem and the parts to be replaced. It is advisable to request quotes from several suppliers to compare costs and services offered. Investing in quality repairs can extend the life of the tower and ensure optimum long-term performance.

Cooling tower lifetime management

Factors influencing the service life of lathes.

The life of cooling towers is influenced by various factors, such as the quality of the water, the frequency of maintenance, the operating environment and the design of the tower. Effective management of these factors can contribute to prolong the sustainability and efficiency of cooling towers .

Strategies for extending cooling tower durability

For extend the life of cooling towers it is recommended to follow a regular maintenance program, monitor, and control the quality of the cooling water, to implement management practices that are water efficient and invest in technology upgrades to improve the overall performance of the tower.

Impact of cooling water quality on service life

Cooling water quality is crucial to the durability of cooling towers. High levels of salts, limescale or contaminants can lead to component corrosion, blockages and long-term damage. It is essential to monitor and maintain water quality to ensure optimum tower operation over the long term.

Definitions

• This invention relates to a counterflow cooling tower comprising heat transfer media in the form of fill sheets comprising the features according to the preamble of claim 1.
• counterflow cooling towers The design of counterflow cooling towers is a well developed technology.
• heat transfer media comprising a plurality of fill sheets are mounted vertically and slightly spaced so as to provide vertical air channels between adjacent sheets, and ambient air is passed upwardly while heated water is flowed downwardly on the surface of the sheets to effect heat exchange to cool the water.
• the fill sheets have been relatively flat parallelograms, usually rectangles, of relatively impervious material with surface embossments to keep adjacent sheets spaced apart and to distribute a film of water on each surface.
• Such sheets have been arrayed in a horizontal bank with the lower edges positioned horizontally and held generally parallel and even with one another at a uniform distance above a water sump or pool in the bottom of the cooling tower so as to provide a rectangular plenum for air to enter beneath the fill sheets, as shown, for example, in US-A-3,132,190 to Engalitcheff Jr.
• a water distribution network is located and balanced so as to deliver substantially uniform rates of water flow to all portions of the fill sheets; and above that an air outlet is located.
• heat transfer media is used throughout this specification to refer to the means for carrying liquid or water or means through or over which liquid or water is passed to be cooled by air flowing into the cooling tower.
• FR-A-1271857, FR-A-2215597 and FR-A-2270539 disclose other known cooling devices.
• FR-A-2270539 discloses a counterflow cooling tower comprising heat transfer media arranged in a vertical bank, so as to be wetted by descending water which is contacted by air entering from one side of said cooling tower beneath the media through an air entry way formed in said one side, such air moving sideways into engagement with a lower extremity of the media and thereafter passing generally upwardly through the media, and a plenum space beneath said media which receives the air entering via said entry way, said plenum space having an interface with the lower extremity of said media, said heat transfer media having an upper extremity extending substantially horizontally.
• FR-A-1271857 describes a forced draft counterflow cooling tower in which the fill sheets of the heat transfer media are positioned some distance above the air entry way in the side of the tower, such that the air is flowing vertically when it encounters them, and are aligned parallel to the entering air flow, in order to ensure that the liquid to be cooled flows down the wall opposite the air entry way so as to eliminate problems caused by drops of liquid falling from the fill sheets.
• FR-A-2215597 discloses another type of counterflow cooling tower in which the heat transfer media comprises sheets arranged in a sloping bank and in which the channels formed in the sheets for liquid and air flow are inclined at varying angles to the horizontal.
• a counterflow cooling tower comprising heat transfer media in the form of fill sheets arranged in a vertical bank and defining a plurality of vertically extending air channels passing therethrough, the media being wetted by descending liquid which is contacted by air entering from one side of said cooling tower beneath the media through an air entry way formed in said one side, and a plenum space beneath the media which receives air entering via the entry way, in which the heat transfer media associated with said air entry way in said one side of the tower has a lower extremity which defines a sloping interface with the plenum space declining downwardly from the top of the air entry way and extending across the entire width of such media, whereby the air entering through said air entry way moves substantially horizontally into engagement with said lower extremity of the media and thereafter passes generally upwardly through the air channels in the media, characterised in that: the fill sheets are arranged in the region of said lower extremity so that the air flow channels defined thereby also extend horizontally in a direction which is parallel to the direction of air flow through
• the present invention allows for a reduction in the overall height of a counterflow cooling tower by organizing heat transfer media in a non symmetrical arrangement therein so that a lower boundary of the media is inclined downwardly toward the bottom of the tower from an air entry side toward a far side of the cooling tower, so as to form a sloped interface with a triangular air plenum from which the horizontally entering air tends to move substantially upwardly upon reaching the media.
• the present invention provides for arranging the media within a cooling tower to slope downwardly from an air entryway, thereby obstructing incremental layers of air moving horizontally into the plenum below the media and turning the incremental air flow upwardly as each layer reaches media interfacing the plenum.
• the preferred form of media is fill sheets of trapezoidal shape suspended so as to be parallel to the direction of entering air flow.
• FIG. 1 An induced draft counterflow cooling tower is illustrated in Figure 1 wherein a plurality of heat transfer media generally 10 are suspended within a generally rectangular enclosure comprising vertical walls 12, a bottom basin 14 (or sump) and an overhead cowling 16 shaped to form a transition cover extending from the walls 12 to an exhaust fan ring 18 which surrounds and supports a multibladed fan 20 driven by an electric motor 22.
• the motor 22 is mounted on the exterior of the cooling tower so as to be clear of the highly humid air discharged therefrom; however the motor 22 may be located within the tower or above the fan discharge.
• the motor 22 is supported on the cowling 16 and is drivingly connected to the fan 20 by an endless belt 24, or the like, extending between sheaves on the motor shaft and fan shaft.
• air is drawn horizontally through an entry way 28 in only one side wall into a plenum space 36 within the cooling tower and moves upwardly between the media 10 and exits through the fan ring 18.
• the bottom of the cooling tower comprises an enclosed basin or sump 14 to receive a descending flow of water that is sprayed on the media 10 from an overhead distribution network comprising a water main 38, distribution pipes 40 and spray nozzles 42. Water is discharged from the basin 14 through a discharge conduit 48.
• a plurality of mist eliminator baffles 50 is positioned above the media 10 and may be conveniently supported above the water distribution pipes 40.
• a preferred form of media 10 in the present invention is non-rectangular fill sheets 58 having trapezoid shaped faces 60 which sheets are suspended in the cooling tower so as to have a horizontal upper edge 62 and a sloped, non-parallel lower edge 64 which extends from a short side edge 66 downwardly, to an opposite parallel and longer side edge 68.
• a plurality of such fill sheets 58 are suspended within the cooling tower with the short side edges 66 disposed toward an air entry side so that the lower edges 64 decline away from the top of an air entry way 28 toward the basin 14 thereby forming a sloped boundary and interface respecting the plenum space 36.
• the present invention involves a novel construction of cooling tower which is formed by orienting the interface between heat transfer media and air plenum to slope downwardly from the top of the air entrance side of the cooling tower thereby resisting continued horizontal movement of increments or layers of air and turning such increments of air to move upwardly through the media.
• the present construction involves increasing the depth of the media as the distance from the air entrance increases (by maintaining the media top substantially at a horizontal level) thereby progressively lengthening both the horizontal and vertical air paths and hence increasing the flow resistance for successive increments or layers of air entering the cooling tower. This results in a relatively greater amount of air flow upwardly at the air entrance to the cooling tower as compared to towers having a horizontal interface between media and plenum and an even depth of media across the tower.
• the fill sheets 58 are oriented to position the faces 60 parallel to the entering air flow (as designated by the arrows "A").
• there are a plurality of substantially identical parallel fill sheets 58 each extending the full vertical depth of the media.
• such media may be constructed of stacked layers (not shown) wherein the upper layer (or layers) may comprise rectangular sheet components arranged vertically, and either parallel or crosswise to the lowermost fill sheets, so long as the latter present a sloping interface with the air plenum 36.
• the sloping interface is obtained by employing non-rectangular fill sheets and orienting a diverging edge 64 downwardly across the plenum 36, and while trapezoidal faces 60 as shown are preferred, it is possible to utilize a triangular fill sheet (not shown).
• mist eliminator baffles 50 are mounted crosswise to the fill sheets (as shown) so as to function to both deflect and guide discharge air away from the intake air space and collect air entrained moisture droplets.
• baffles 50 may be repositioned if air is to be deflected in a different direction.
• the water distribution spray nozzles 42 may be adjusted to supply relatively lesser quantities of water adjacent the fill sheet short side edges 66 as compared to the longer side edges 68 to partially balance the effect of the relative cooling paths of increments of water descending along the fill sheet faces 60 when appropriate to fill height and density conditions. However, that effect is also at least partially balanced by a relatively lower resistance to air flow, and hence greater rate of air flow, across the shorter cooling paths.
• the preferred fill sheets have sloped lower edges 64 there is a tendency for some of the descending water to temporarily collect in the form of beads which run down the lower edge rather than to drop into the plenum space 36. In excessive amounts and circumstances such beading on adjacent fill sheets could bridge the space between sheets and interfere with air flow distribution. To counteract such a possibility the lower edges 64 of interdigitating fill sheets are alternately offset a small vertical distance (as shown by a phantom line 70 in Figure 1.
• fill sheets generally 10 are shown in Figure 4.
• Formed rectangular stock 80 of plastic film is available as the usual type of rectangular fill sheet in a wide range of dimensions.
• Such stock usually is embossed with a uniform pattern of contours 82, which define pathways and generally increase the surface area across which water is spread in the cooling tower, and one or more stiffening ridges 84 and margins.
• the stock is embossed to include a plurality of spacer projections 86 extending in two directions perpendicular to the plane of the sheet which projections nest when the sheets are stacked but serve to keep adjacent sheets spaced apart when suspended in a cooling tower in an offset interdigatating manner.
• the rectangular stock 80 is cut at an angle, as shown by the dashed line in Figure 4, between points on opposite sides equally spaced from the longer edges thereof.
• the specific dimensions and the slope angle of the non-parallel edge may be adapted to the size limitations of a cooling tower.
• FIG. 2 illustrates a preferred embodiment of the present invention utilizing trapezoidal fill sheets 58'' in a forced draft counterflow cooling tower having a centrifugal fan 94.
• the fill sheets 58 are aligned with the incoming air propelled by the fan 94 through a transition duct 96. It has been found that the horizontal distribution of air from such a fan 94 is improved if the fan shaft 98 is slightly elevated and the fan discharge aimed through a gradually flared transition duct 96 which expands to approximately the dimensions of the inlet side 28'' of plenum 36''.
• Another advantage of aligning the fill sheets 60'' with the forceful air streams from a centrifugal fan 94 is that the lower edges 64'' of the sheets have a lessened tendency to flutter and thereby air flow between the sheets is facilitated.
• An example of a forced draft (centrifugal fan) counterflow cooling tower having exterior width and length dimension of 1.2 m x 1.82 m (48 x 71 3/4 inches) (exclusive of fan and entry duct) and height of 2.00 m (78 3/4 inches), containing seventy eight trapezoidal fill sheets suspended lengthwise, can supply approximately 50.7 tonnes (55.9 tons) of cooling capacity by cooling 38.1 m3 per hour (167.7 gallons of water per minute) from 35°C (95°F) inlet to 29.5°C (85°F) discharge using 444 m3 per minute (15670 cubic feet per minute) of 26°C (78°F) ambient air supplied by a centrifugal fan driven with a 3.7 kw (5 horsepower) motor.
• FIG 3 illustrates an induced draft cooling tower provided with two air entry ways 28a and 28b at opposite walls 12'' of the cooling tower and two banks of fill sheets 10a and 10b above plenum spaces 36a and 36b.
• the cooling tower is generally symmetrical about a central vertical plane and parts corresponding to those described in connection with Figure 1 are denominated by the same reference character with a double prime notation. It is also possible to construct a forced draft embodiment of a symmetrical unit similar to the induced draft embodiment of Figure 2.
