Abstract

The refrigerating plant for a liquid, for example beer, includes a heat exchanger, a compressor, and a condenser. The exchanger fits into the upper part of a sealed cylinder and forms the evaporator coil. In the lower part of the cylinder there are two sets of coiled pipes through which the liquid to be cooled flows. There are several concentric helices to each of the sets of coils, the fluid entering the innermost coil and then passing to the outer coils as it gets colder. The cylindrical container of the heat exchanger contains water, carrying heat from the lower coils, which contain the liquid to be cooled, to the upper evaporater coil. The warmer water rises up through the centre of the cylinder while cooled water falls down around the circumference of the cylinder.

Description

L'invention se rapporte à une nouvelle installation de réfri- gération instantanee d'un liquide en circulation et plus particu lièrement, parce qu'elle y trouve une application préférentielle, à une installation de réfrigération de la bière soit lors de sa fabrication (refroidissement du moût, fermentation) soit lors de son débit sous pression. The invention relates to a new installation for instantaneous refrigeration of a circulating liquid and more particularly, because it finds there a preferential application, to an installation for refrigerating beer either during its manufacture (cooling must, fermentation) or during its flow under pressure.

Actuellement, les installations de réfrigération de cette boisson comporte un echangeur thermique constitué par : le serpentin de circulation de la bière immergé dans une cuve d'eau refroidie par l'évaporateur d'un groupe Priqorifique utilisant un conpresseur peu puissant mais travaillant sur de longues périodes. Currently, the refrigeration installations for this drink include a heat exchanger consisting of: the beer circulation coil immersed in a tank of water cooled by the evaporator of a Priqorific group using a weak compressor but working on long periods.

I1 est bien connu que l'eau servant d'agent intermédiaire, transfere les frigories par conduction avec un rendement médiocre. It is well known that water acting as an intermediate agent transfers frigories by conduction with a poor yield.

I1 est aussi connu des installations ayant même but mais fonctionnant selon un principe tout différent, à savoir : que la réfri- gération du liquide en circulation est obtenue par vaporisation d'un liquide frigorifique, obtenue par l'apport calorifique du liquide circulant dans le serpentin y baignant, l'évaporateur du groupe frigorifique n'ayant plus pour mission que de condenser les vapeurs du liquide frigorifique ainsi produites. It is also known from installations having the same purpose but operating according to a completely different principle, namely: that the refrigeration of the liquid in circulation is obtained by vaporization of a refrigerating liquid, obtained by the calorific contribution of the liquid circulating in the coil in it, the evaporator of the refrigeration unit no longer having the task of condensing the vapors of the refrigerant thus produced.

De telles installations ont des rendements bien supérieurs à celles utilisant l'échange biere/eau mais le refroidissement par air qu'elles necessitent présente de sérieuses di ffi cul tés quand le débit de biere est important puisque le débit d'air de refroidissement lui est sensiblement proportionnel. Comme celui-ci doit être évacue dans l'atmosphère, il est bien évident que si son volume est grand, il modifie les conditions climatiques du local et reduit le rendement du compresseur, si bien que les installations comportant ce type de refroidissement sont oblioatoirement limitées aux petits et moyens débits. Such installations have much higher yields than those using the beer / water exchange, but the air cooling they require presents serious difficulties when the flow of beer is high since the flow of cooling air is substantially proportional. As it must be discharged into the atmosphere, it is obvious that if its volume is large, it changes the climatic conditions of the room and reduces the efficiency of the compressor, so that the installations comprising this type of cooling are necessarily limited at small and medium flows.

La présente invention vise une installation de ce type mais amenagée en vue d'être utilise sans limite d'importance de débit du liquide, bière par exemple. The present invention relates to an installation of this type but arranged to be used without limit of importance of flow rate of the liquid, beer for example.

D'autres particularités et avantages de l'invention apparaîtront à la lecture de la description et des revendications qui suivent, faites en regard du dessin annexé sur lequel, à titre d'exemple non limitatif,
La figure 1 est un schéma d'une installation selon 1'invention,
La figure 2 est une vue en coupe d'un mode de réalisation d'un échangeur de température,
la figure 3 en est une vue explosée en perspective.Other features and advantages of the invention will appear on reading the description and the claims which follow, made with reference to the appended drawing in which, by way of nonlimiting example,
FIG. 1 is a diagram of an installation according to the invention,
FIG. 2 is a sectional view of an embodiment of a temperature exchanger,
Figure 3 is an exploded perspective view.

Comme on le voit sur ces figures, l'installation comprend un échangeur (El), un groupe frigorifique à compresseur (GF) dans le circuit duquel est place un condenseur (CD). As can be seen in these figures, the installation comprises an exchanger (El), a compressor refrigeration unit (GF) in the circuit of which a condenser (CD) is placed.

L'échangeur (E1) comprend dans une cuve étanche (1), à la partie supérieure (la), le serpentin de l'évaporateur (2) du groupe frigorifique extérieur (GF) (entrée 2a - sortie 2b) et à la partie inférieure (lb) un ou plusieurs serpentins (3) de circulation du fluide à réfrigérer. The exchanger (E1) comprises, in a sealed tank (1), at the upper part (la), the evaporator coil (2) of the external refrigeration unit (GF) (inlet 2a - outlet 2b) and at the part lower (lb) one or more coils (3) for circulation of the fluid to be refrigerated.

Le niveau initial du liquide frigorifique par exemple de l'anhydride sulfureux, de l'ammoniac, de l'anhydride carbonique, du chlorure d'éthyle ou de méthyle ou tout spécialement du dichlorodifluo rométhane plus connu sous la marque FREON introduit dans la cuve après vide absolu est situé au-dessous de l'évaporateur (2). The initial level of the refrigerating liquid, for example sulfur dioxide, ammonia, carbon dioxide, ethyl or methyl chloride or especially dichlorodifluo romethane better known under the brand FREON introduced into the tank after absolute vacuum is located below the evaporator (2).

Le ou les serpentins (3) sont formes d'une pluralite d'hélices concentriques autour d'un canal axial (4). Les hélices communiquent entre elles de maniere à former un circuit allant de l'entrée (3a) à la sortie (3b), l'entrée (3a) étant reliée à l'hélice la plus centrale tandis que la sortie s'effectue par l'hélice la plus exterieure. The coil (s) (3) are formed from a plurality of concentric helices around an axial channel (4). The propellers communicate with each other so as to form a circuit going from the inlet (3a) to the outlet (3b), the inlet (3a) being connected to the most central propeller while the outlet is carried out by the outermost propeller.

De cette manière, le liquide "chaud" subit un premier refroidissement dans cette helice intérieure en commençant à produire ou entretenir l'évaporation du liquide frigorifique. Cette action se continue dans l'hélice suivante, la température du liquide circulant étant progressivement de plus en plus froide. In this way, the "hot" liquid undergoes a first cooling in this internal propeller by starting to produce or maintain the evaporation of the refrigerating liquid. This action continues in the next propeller, the temperature of the circulating liquid being progressively colder and colder.

Les vapeurs du liquide frigorifique se condensent sur l'evaporateur frigorifique (2) puis retombent en phase liquide pour baigner à nouveau le ou les serpentins (3). The vapors of the refrigerating liquid condense on the refrigerating evaporator (2) then fall back into the liquid phase to bathe the coil (s) again (3).

Cette disposition permet de placer dans un encombrement minimal, un serpentin de grande longueur avec pour conséquence de réaliser d'une part un volant thermique important favorisant l'ébullition du liquide frigorifique et d'autre part une grande surface d'échanges
augmentant très sensiblement les possibilités et la rapidité de
refroidissement.This arrangement makes it possible to place in a minimal space, a coil of great length with the consequence of producing on the one hand a large thermal flywheel favoring the boiling of the refrigerating liquid and on the other hand a large exchange surface
greatly increasing the possibilities and speed of
cooling.

Enfin2 cette construction permet de placer l'entrée (3a) soit
à la partie centrale du serpenti(visible pour le serpentin inférieur
de la-fig 2, soit à la partie supérieure du serpentin comme visi
ble à titre de variante sur le serpentin de circulation supérieur
(même figure).Finally2 this construction makes it possible to place the entry (3a) either
at the central part of the snake (visible for the lower coil
de-fig 2, either at the top of the coil as visi
ble as a variant on the upper circulation coil
(same figure).

L'arrivée au centre et la sortie à l'extérieur est plus rationnelle cequeconfirme les essais effectués par la demanderesse Ce qui s'ex-
plique d'ailleurs aisément puisque les bulles du liquide frigorifi- que mis en ébullition par l'arrivée du liquide "chaud" a la partie centrale montant par la cheminée centrale (3G) créent un courant ascensionnel mettant en mouvement 1 liquide frigorifique favorisant ainsi les échanges thermiques sans avoir recoursàunagitateur
Avantageusement, la cuve étanche (1) est constituée par deux
coquilles (lm) et (ln) soudées entre elles selon des genératrices
longitudinales et fermées par deux fonds (lp) et (1r).The arrival at the center and the exit outside is more rational, which confirms the tests carried out by the applicant.
folds easily since the bubbles of the refrigerating liquid brought to the boil by the arrival of the "hot" liquid at the central part rising through the central chimney (3G) create an upward current setting in motion 1 refrigerating liquid thus favoring the heat exchanges without using an agitator
Advantageously, the sealed tank (1) consists of two
shells (lm) and (ln) welded together according to generators
longitudinal and closed by two bottoms (lp) and (1r).

Les entrée et sortie de l'évaporateur9 et du ou des serpentins
traversent d'une manière étanche la paroi de la cuve (1).The inlet and outlet of the evaporator9 and the coil (s)
pass through the wall of the tank (1) in a leaktight manner.

Le fond supérieur (lp) comporte un puits axial (lut) pour la mise en place d'une sonde permettant la prise de température voire
une commande thermostatique. The upper bottom (lp) has an axial well (lut) for the installation of a probe allowing the temperature to be taken or even
a thermostatic control.

Du fait de sa construction9 l echangeur (E1) permet si on le désire de réfrigérer simultanément avec le même dispositifs plusieurs liquides différents. Due to its construction9 the exchanger (E1) allows, if desired, to refrigerate several different liquids simultaneously with the same device.

Comme on le voit sur la fig. I > le groupe frigorifique (GF) pompe le fluide par la canalisation (2b) et l'envoie dans le serpentin (Cd1) du condenseur (Cd) par la canalisation (4) d'où il ressort refroidi par une canalisation (5) aboutissant à la canal i- sation (2a) de l'évaporateur. As seen in fig. I> the refrigeration unit (GF) pumps the fluid through the pipe (2b) and sends it into the coil (Cd1) of the condenser (Cd) through the pipe (4) from which it emerges cooled by a pipe (5) leading to the i-channel (2a) of the evaporator.

L'enceinte du condenseur (Cd) est remplie d'eau de distribution
sous pression (6) qui, réchauffée en ressort par la canalisation
d'écoulement (7).The condenser enclosure (Cd) is filled with tap water
under pressure (6) which, reheated out of the pipe
flow (7).

Un pressostat (Pr) contrôle la pression de la canalisation (4),
de manière à eviter une surpression dans le système, du fait d'une
augmentation exagérée de la température dans le condenseur (Cd) par exemple dans le cas où l'eau de refroidissement y venait à manquer. Le pressostat (Pr) aurait alors pour mission de couper l'alimentation électrique du compresseur.A pressure switch (Pr) controls the pressure of the pipe (4),
so as to avoid an overpressure in the system, due to a
exaggerated increase in the temperature in the condenser (Cd) for example in the event that the cooling water ran out there. The pressure switch (Pr) would then have the task of cutting the electrical supply to the compressor.

De même, une vanne thermostatique (Vt) ayant sa sonde (Sv) placée sur la canalisation (5), contrôle la température des gaz y circulant, de manière à régler le débit d'eau de refroidissement en fonction de la température des gaz.  Likewise, a thermostatic valve (Vt) having its probe (Sv) placed on the pipe (5), controls the temperature of the gases circulating therein, so as to regulate the flow of cooling water as a function of the temperature of the gases.
