Description

Cette invention se rapporte à un comptoir frigorifique du type ouvert ventilé qui est constitué, entre autres, d'une plaque inférieure et d'une plaque de base destinée à l'exposition des produits (aliments) entre lesquelles de l'air refrigéré refroidi par des éléments refroidisseurs est mis en circulation par plusieurs ventilateurs disposés sur la longueur de ces plaques.This invention relates to a refrigerated counter of the ventilated open type which consists, inter alia, of a lower plate and a base plate intended for the exposure of products (food) between which refrigerated air cooled by cooling elements is circulated by several fans arranged along the length of these plates.

De tels comptoirs frigorifiques sont connus. Ils sont utilisés essentiellement dans le secteur de l'alimentation.Such refrigeration counters are known. They are mainly used in the food sector.

Le but de l'invention est de prescrire un comptoir frigorifique du type décrit dans le préambule, comptoir dont le rendement se trouve sensiblement amélioré. On entend par là que la température au-dessus des produits (aliments) demeure dans la gamme de 2° à 5°C et cela jusqu'à une hauteur d'environ 15 cm, le degré d'humidité demeurant extrêmement avantageux. Un degré d'humidité très favorable est celui dans lequel le degré d'humidité comporte 75-85°C au-dessus des produits pour une température ambiante d'environ 22°C dans l'espace du magasin.The object of the invention is to prescribe a refrigeration counter of the type described in the preamble, a counter whose performance is significantly improved. This means that the temperature above the products (food) remains in the range of 2 ° to 5 ° C and this up to a height of about 15 cm, the degree of humidity remaining extremely advantageous. A very favorable humidity level is that in which the humidity level comprises 75-85 ° C above the products for an ambient temperature of approximately 22 ° C in the store space.

Pour réaliser ceci conformément à l'invention, figurent entre la plaque inférieure et la plaque de base, dans le sens dans lequel circule l'air, les éléments ou structures ci-après:

  • 1. Un premier évaporateur disposé sous les ventilateurs précités;
  • 2. Un second évaporateur qui se trouve à une distance de la plaque de base précitée et de la plaque inférieure précitée;
  • 3. Une gouttière prévue dans la plaque inférieure précitée et équipée d'une résistance chauffante;
  • 4. Un troisième évaporateur disposé tout juste face à une fente de sortie longitudinale (13) pour l'air refroidi.
To achieve this in accordance with the invention, there are between the lower plate and the base plate, in the direction in which the air circulates, the following elements or structures:
  • 1. A first evaporator placed under the fans above;
  • 2. A second evaporator which is located at a distance from the aforementioned base plate and the aforementioned lower plate;
  • 3. A gutter provided in the aforementioned lower plate and equipped with a heating resistance;
  • 4. A third evaporator located just opposite a longitudinal outlet slot (13) for the cooled air.

Toujours selon l'invention, la fente longitudinale de sortie précitée est profilée de telle sorte entre les bords longitudinaux de la plaque inférieure précitée et de la plaque de base que l'air refroidi qui s'en échappe est dirigé en direction des produits (aliments) reposant sur la plaque de base.Still according to the invention, the aforementioned longitudinal outlet slot is profiled in such a way between the longitudinal edges of the aforementioned lower plate and of the base plate that the cooled air which escapes therefrom is directed towards the products (food ) resting on the base plate.

Un détail de l'invention réside dans le fait qu'il est disposé, entre le ventilateur précité et le premier évaporateur, une plaque déflectrice perforée en vue d'optimaliser la répartition de l'air par dessus l'évaporateur précité.A detail of the invention lies in the fact that there is disposed, between the aforementioned fan and the first evaporator, a perforated deflector plate in order to optimize the distribution of air over the aforementioned evaporator.

D'autres détails et avantages de l'invention ressortiront de la description qui sera donnée ci-après d'un comptoir frigorifique du type ouvert ventilé, selon l'invention. Cette description est donnée uniquement à titre d'exemple et ne limite pas l'invention. Les notations de référence se rapportent aux figures ci-annexées.Other details and advantages of the invention will emerge from the description which will be given below of a refrigerated counter of the ventilated open type, according to the invention. This description is given only by way of example and does not limit the invention. The reference notations refer to the appended figures.

La figure 1 est une coupe transversale au travers des éléments essentiels d'un comptoir frigorifique selon l'invention.Figure 1 is a cross section through the essential elements of a refrigeration counter according to the invention.

La figure 2 est une coupe transversale au travers de la plaque déflectrice disposée au-dessus du premier évaporateur. (coupe à une échelle plus grande).Figure 2 is a cross section through the deflector plate disposed above the first evaporator. (cut to a larger scale).

Le comptoir frigorifique selon l'invention consiste essentiellement dans les éléments essentiels ci-après, à savoir une plaque inférieure 1, et une plaque de base 2. La plaque de base 2 est reliée, à l'arrière du comptoir, à une plaque verticale 3, tandis que la plaque inférieure 1 se transforme en une partie verticale 4.The refrigeration counter according to the invention essentially consists of the following essential elements, namely a lower plate 1, and a base plate 2. The base plate 2 is connected, at the rear of the counter, to a vertical plate 3, while the lower plate 1 is transformed into a vertical part 4.

La distance entre la plaque inférieure 1 et la plaque de base 2 est suffisamment vaste pour y inclure deux évaporateurs à une distance telle de ces plaques qu'on ne doit pas craindre le givrage essentiellement de la plaque de base.The distance between the bottom plate 1 and the base plate 2 is wide enough to include two evaporators at such a distance from these plates that one should not fear the icing essentially of the base plate.

Afin de garantir un rendement très élevé, le comptoir frigorifique comporte successivement (cette expression est utilisée en considérant le sens de déplacement de l'air de l'arrière vers l'avant) un ventilateur 5 et un premier évaporateur 6 suivi d'un second évaporateur 7 et ensuite d'un troisième ou dernier évaporateur 8. Sous le premier évaporateur 6 est prévue au moins une petite gouttière 9 pour capter l'eau de condensation. Dans cette gouttière 9 est prévue une résistance de dégivrage 10.In order to guarantee a very high efficiency, the refrigeration counter successively comprises (this expression is used when considering the direction of movement of the air from the rear to the front) a fan 5 and a first evaporator 6 followed by a second evaporator 7 and then a third or last evaporator 8. Under the first evaporator 6 is provided at least one small gutter 9 to capture the condensation water. A defrost resistor 10 is provided in this gutter 9.

Quoique ceci ne soit pas limitatif pour les propriétés caractérisantes du comptoir frigorifique selon l'invention, on choisit pour le premier évaporateur un évaporateur comportant vingt tuyaux et présentant une distance d'environ 12 mm entre les ailettes. Ce premier évaporateur 6 est monté dans un boîtier 6'. Ce boîtier 6' est complètement ouvert à sa partie supérieure et complètement fermé à sa partie arrière, et ouvert pour un tiers à sa partie antérieure. A sa partie inférieure le boîtier 6' présente une plaque inclinée 6'' qui est ouverte sur un tiers. Celle-ci est également conçue pour diriger l'air refroidi vers l'évaporateur 7. Pour le second évaporateur 7 on fait usage d'un évaporateur équipé de préférence de vingt-quatre tuyaux avec une distance d'environ 10 mm entre les ailettes. Dans le troisième évaporateur 8 se rencontrent de préférence six tuyaux avec une distance d'environ 12 mm entre les ailettes. La distance entre les évaporateurs et la plaque inférieure 1 est d'environ 2 cm de telle sorte que lors du givrage des évaporateurs 7 et 8, le passage de l'air n'est pas gêné. Entre les second et troisième évaporateurs, respectivement 7 et 8, est prévue une petite gouttière 11 équipée d'une résistance de chauffage 12. L'eau qui se trouve dans cette petite gouttière 11 est réchauffé jusqu'à une température qui se situe entre environ 30° et 40°C. Grâce à cette gouttière équipée d'une résistance de chauffage entre les évaporateurs 7 et 8 on obtient une température de sortie qui se situe entre environ 0° et -3°C. Ceci nécessite une circulation lente de l'air pour empêcher la dessiccation des produits (aliments) exposés et ceci est en effet réalisé grâce au profilage particulier de la fente longitudinale de sortie 13 grâce à laquelle l'air refroidi est fortement humidifié et répandu par dessus les produits (aliments). La hauteur maximale à laquelle cet air froid humide circule par dessus les produits est d'environ 15 cm. Afin d'assurer l'épandage désiré de l'air froid, la plaque inférieure 1 est repliée elle-même sous la forme d'un déflecteur ou est pourvue à sa partie antérieure d'un élément de plaque recourbé 14. Face à cet élément de plaque 14, la plaque de base 2 est équipée d'un bord replié 2' de telle sorte que l'air refroidi et fortement humidifié peut être répandu selon le schéma désiré par dessus les produits (voir la flèche 15).Although this is not limiting for the characterizing properties of the refrigeration counter according to the invention, for the first evaporator is chosen an evaporator comprising twenty pipes and having a distance of approximately 12 mm between the fins. This first evaporator 6 is mounted in a housing 6 '. This box 6 ′ is completely open at its upper part and completely closed at its rear part, and open for a third at its front part. At its lower part the housing 6 'has an inclined plate 6''which is open to a third. This is also designed to direct the cooled air to the evaporator 7. For the second evaporator 7, an evaporator equipped with preferably twenty-four pipes with a distance of about 10 mm between the fins. In the third evaporator 8, there are preferably six pipes with a distance of approximately 12 mm between the fins. The distance between the evaporators and the bottom plate 1 is approximately 2 cm so that during the icing of the evaporators 7 and 8, the passage of air is not impeded. Between the second and third evaporators, respectively 7 and 8, is provided a small gutter 11 equipped with a heating resistor 12. The water which is in this small gutter 11 is heated to a temperature which is between approximately 30 ° and 40 ° C. Thanks to this gutter fitted with a heating resistor between the evaporators 7 and 8, an outlet temperature is obtained which is between approximately 0 ° and -3 ° C. This requires a slow circulation of air to prevent drying of the exposed products (food) and this is in fact achieved thanks to the particular profiling of the longitudinal outlet slot 13 thanks to which the cooled air is strongly humidified and spread over it. products (food). The maximum height at which this cold humid air circulates over the products is approximately 15 cm. In order to ensure the desired spreading of cold air, the lower plate 1 is folded itself in the form of a deflector or is provided at its front part with a curved plate element 14. Facing this element plate 14, the base plate 2 is equipped with a folded edge 2 'so that the cooled and highly humidified air can be spread according to the desired scheme over the products (see arrow 15).

Les températures et les degrés d'humidité désirés sont maintenus lors d'une utilisation normale du comptoir. Les produits (aliments) stockés dans le comptoir doivent, lorsqu'ils sont introduits dans le comptoir, être refroidis au préalable tandis que la température de l'air ambiant ne peut pas se situer au-dessus d'environ 22°C avec un degré d'humidité d'au moins 60 %.The desired temperatures and humidity levels are maintained during normal use of the counter. Products (food) stored in the counter must, when introduced into the counter, be cooled beforehand while the ambient air temperature cannot be above about 22 ° C with a degree of humidity of at least 60%.

Afin de réaliser le rendement élevé des divers évaporateurs, il est disposé au-dessus de l'évaporateur 6 une plaque deflectrice perforée 16. La figure 2 montre une coupe transversale d'une telle plaque. Grâce à la présence de cette plaque déflectrice perforée un épandage optimal de l'air propulsé par le ventilateur 5 le long des éléments du premier évaporateur 6 est garanti.In order to achieve the high efficiency of the various evaporators, a perforated deflector plate 16 is placed above the evaporator 6. FIG. 2 shows a cross section of such a plate. Thanks to the presence of this perforated deflector plate, optimal spreading of the air propelled by the fan 5 along the elements of the first evaporator 6 is guaranteed.

Des avantages de comptoires frigorifiques ouverts, selon l'invention, sont le refroidissement régulier et les faibles écarts de température qui, grâce à la présence de la fente longitudinale de sortie 13 garantit un épandage optimal du courant d'air froid et humide sur les produits. Le brouillard très fin et de dispersion lente qui forme un brouillard givrant alourdit l'air de sortie qui se répand ainsi de façon très régulière sur les produits (aliments) exposés.Advantages of open refrigerated counters according to the invention are regular cooling and small temperature differences which, thanks to the presence of the longitudinal outlet slot 13 guarantees optimal spreading of the cold and humid air flow on the products. . The very fine mist and slow dispersion which forms an icing mist increases the outlet air which spreads very evenly over the products (food) exposed.

La croissance de bactéries est pratiquement exclue grâce à la présence de l'air très froid au-dessus de la gouttière 11 qui agit en temps que gouttière d'évaporation. La gouttière ouverte destinée à recevoir de l'eau a, en particulier, l'avantage qu'une phase vapeur prend naissance et qu'on ne doit donc pas craindre un croissance d'algues.The growth of bacteria is practically excluded thanks to the presence of very cold air above the gutter 11 which acts as an evaporation gutter. The open gutter intended to receive water has, in particular, the advantage that a vapor phase arises and that there is therefore no fear of algae growth.
