Abstract
Description
La présente invention concerne le domaine des machines thermiques, en particulier des pompes à chaleur, des machines frigorifiques, et analogues, et a pour objet un condenseur à deux températures pour de telles machines. The present invention relates to the field of thermal machines, in particular heat pumps, refrigeration machines, and the like, and relates to a two-temperature condenser for such machines.
Actuellement, dans les machines thermiques existantes, le liquide réfrigérant issu du réservoir de liquide réfrigérant subit un refroidissement complémentaire par passage dans un échangeur de chaleur, dans lequel passe le gaz aspiré par le compresseur et venant de l'évaporateur, afin d'augmenter le rendement de l'installation. Currently, in existing thermal machines, the coolant from the coolant tank undergoes additional cooling by passage through a heat exchanger, through which the gas drawn by the compressor and coming from the evaporator passes, in order to increase the installation performance.
Cependant, dans ces machines connues, le refroidissement complémentaire du liquide réfrigérant est relativement faible, de sorte que le rendement est peu modifié. However, in these known machines, the additional cooling of the coolant is relatively low, so that the yield is little modified.
La présente invention a pour but de pallier ces inconvénients. The present invention aims to overcome these drawbacks.
Elle a, en effet, pour objet un condenseur pour machines thermiques, caractérisé en ce que sa sortie est reliée à un réservoir de liquide réfrigérant dans lequel pénètre un tuyau de départ de liquide relié par l'intermédiaire d'une vanne d'expansion à l'entrée de l'évaporateur, dont la sortie est munie d'un serpentin logé dans le réservoir de liquide réfrigérant et relié par son autre extrémité à l'aspiration du compresseur. Its purpose is in fact a condenser for thermal machines, characterized in that its outlet is connected to a reservoir of coolant liquid into which enters a liquid start pipe connected by means of an expansion valve to the inlet of the evaporator, the outlet of which is provided with a coil housed in the coolant reservoir and connected by its other end to the suction of the compressor.
L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dont la figure unique est un schéma d'un compresseur muni d'un condenseur conforme à l'invention. The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, the single figure of which is a diagram of 'A compressor fitted with a condenser according to the invention.
Le compresseur 1, représenté au dessin annexé, est muni d'un condenseur 2 à double tube, connu en soi, dont le tube extérieur est relié à un circuit 3 de chauffage, ou autre. Conformément à l'invention, la sortie du condenseur 2 débouche dans un réservoir 4 à liquide réfrigérant, dans lequel pénètre un tuyau 5 de départ de liquide relié par l'intermédiaire d'une vanne d'expansion 8 à l'évaporateur 6 dont la sortie est pourvue d'un serpentin 7 logé dans le réservoir 4 et qui est relié par son autre extrémité à l'aspiration du compresseur 1. The compressor 1, shown in the accompanying drawing, is provided with a double tube condenser 2, known per se, the outer tube of which is connected to a heating circuit 3, or the like. According to the invention, the outlet of the condenser 2 opens into a coolant reservoir 4, into which enters a pipe 5 for starting the liquid connected via an expansion valve 8 to the evaporator 6, the outlet is provided with a coil 7 housed in the tank 4 and which is connected by its other end to the suction of the compressor 1.
Le gaz comprimé chaud issu du compresseur 1 se condense dans le condenseur 2 où il transmet une partie de sa chaleur au circuit 3, de sorte qu'il se forme une condensation partielle et qu'à la sortie du condenseur on obtient un mélange de gaz et de liquide chauds, qui pénètre librement dans le réservoir 4. Dans ce dernier, le gaz est refroidi au contact du serpentin 7 prolongeant l'évaporateur 6 avant de pénétrer sous forme liquide dans le tuyau 5. The hot compressed gas from the compressor 1 condenses in the condenser 2 where it transmits part of its heat to the circuit 3, so that a partial condensation is formed and at the outlet of the condenser a mixture of gases is obtained and hot liquid, which freely penetrates into the tank 4. In the latter, the gas is cooled in contact with the coil 7 extending the evaporator 6 before entering in liquid form in the pipe 5.
La circulation du gaz froid provenant de l'évaporateur 6 dans le serpentin 7 a pour effet d'abaisser la température du liquide réfrigérant contenu dans le réservoir 4 ainsi que celle du gaz et du liquide provenant du condenseur 2, et donc de récupérer la chaleur de ces derniers pour réchauffer les gaz avant leur entrée dans le compresseur 1. En outre, du fait de la bassestempérature engendrée dans la partie inférieure du réservoir 4, il se produit dans ce dernier une différence de pression tendant à vider les tubes du condenseur 2 et ainsi à abaisser la température de sortie du liquide, qui ne peut plus engorger lesdits tubes. The circulation of the cold gas coming from the evaporator 6 in the coil 7 has the effect of lowering the temperature of the coolant contained in the tank 4 as well as that of the gas and the liquid coming from the condenser 2, and therefore of recovering the heat of the latter to heat the gases before they enter the compressor 1. In addition, due to the low temperature generated in the lower part of the tank 4, there occurs in the latter a pressure difference tending to empty the tubes of the condenser 2 and thus to lower the outlet temperature of the liquid, which can no longer clog said tubes.
Grâce à l'invention, il est possible de réaliser un meilleur refroidissement du liquide réfrigérant tout en permettant un fonctionnement à un rendement optimal du compresseur, la condensation des gaz dans le condenseur étant favorisée, et leur entrée dans le compresseur s'effectuant à une température plus élevée que dans les machines existantes. Thanks to the invention, it is possible to achieve better cooling of the coolant while allowing operation at optimum efficiency of the compressor, the condensation of the gases in the condenser being favored, and their entry into the compressor taking place at a higher temperature than in existing machines.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
