Grupo refrigerador para ataúdes con elemento enfriador separable.Coffin group for caskets with element separable cooler.
La presente invención se refiere a un grupo refrigerador para ataúdes, que comprende un circuito refrigerador y un elemento refrigerante en intercambio térmico con el interior del ataúd.The present invention relates to a group coffin refrigerator, comprising a refrigerator circuit and a cooling element in thermal exchange with the interior of the coffin.
En particular, la invención se refiere a un grupo refrigerante del tipo antedicho en el cual el elemento refrigerante comprende un elemento separable por el cual circula un fluido de intercambio térmico.In particular, the invention relates to a group refrigerant of the above type in which the element refrigerant comprises a separable element through which a heat exchange fluid
En la especialidad se conocen grupos refrigeradores similares, tales como, por ejemplo, la patente europea núm. EP 0.230.595 a nombre de la misma solicitante. Esta realización presenta un grupo refrigerante por circulación de freon compuesto por dos partes: una, formada por todos los componentes de un circuito refrigerador (preferentemente contenido en un contenedor transportable), y por otra parte en particular el bloque refrigerante que constituye el refrigerador, consiste en un serpentín precargado que puede acoplarse o separarse del resto del circuito refrigerador por medio de puntos de acoplamiento rápido dispuestos en los tubos de entrada y de salida del bloque a fin de cerrar las respectivas partes del circuito refrigerante después de la separación. Todos los elementos del circuito refrigerador, excepto el elemento, pueden seguidamente acoplarse a otro bloque asociado a otro ataúd.Groups are known in the specialty similar refrigerators, such as, for example, the patent European No. EP 0.230.595 in the name of the same applicant. Is embodiment presents a cooling group by circulation of Freon composed of two parts: one, consisting of all components of a refrigerator circuit (preferably content in a transportable container), and on the other hand in particular the refrigerant block that constitutes the refrigerator, consists of a preloaded coil that can be attached or separated from the rest of the cooling circuit by means of quick coupling points arranged in the inlet and outlet tubes of the block in order to close the respective parts of the refrigerant circuit after the separation. All the elements of the refrigerator circuit, except the element, they can then be coupled to another block associated with another coffin.
El elemento refrigerante se gasta, dado que el circuito se deja dentro del ataúd tras el cierre definitivo del mismo, y ello implica la pérdida del volumen de freon contenido en el elemento. Debe observarse que la cantidad de freon contenida en el evaporador durante el funcionamiento es considerablemente superior al precargado en el evaporador a la temperatura ambiente.The cooling element is worn out, since the circuit is left inside the coffin after the definitive closure of the same, and that implies the loss of freon volume contained in the element. It should be noted that the amount of freon contained in the evaporator during operation is considerably higher than preloaded in the evaporator at the temperature environment.
En el momento de la separación del evaporador respecto al resto del circuito se producen otras pérdidas menores que la antedicha, pero aún importantes, en los puntos de acoplamiento rápido, y dichas pérdidas se deben a la diferencia entre la presión del freon en el serpentín y la presión atmosférica del ambiente exterior.At the time of evaporator separation with respect to the rest of the circuit there are other minor losses that the above, but still important, in the points of quick coupling, and these losses are due to the difference between the freon pressure in the coil and the pressure atmospheric outside environment.
Para superar estos inconvenientes, en la solicitud de patente italiana n° 1.264.864 de la misma solicitante se describe un dispositivo que comprende un doble circuito refrigerante. Comprende un circuito primario (por el cual circula un primer fluido de intercambio térmico) que comporta un elemento refrigerante y medios para asegurar la circulación de dicho líquido de intercambio térmico, medios para interrumpir el circuito de circulación y permitir la extracción del líquido del circuito antes de la separación del elemento del resto del dispositivo, y otro circuito por el cual circula líquido refrigerante y que se halla en intercambio térmico indirecto con el primero.To overcome these inconveniences, in the Italian patent application No. 1,264,864 of the same applicant a device comprising a double circuit is described refrigerant. It comprises a primary circuit (through which it circulates a first heat exchange fluid) that involves an element refrigerant and means to ensure the circulation of said liquid of thermal exchange, means to interrupt the circuit of circulation and allow the extraction of liquid from the circuit before of separating the element from the rest of the device, and another circuit through which coolant circulates and is in indirect thermal exchange with the first.
De esta manera se impidió la pérdida de líquido hacia el exterior y además pudo evitarse la pérdida de líquidos nocivos al tener un líquido circulando por el elemento, cuya función era simplemente la de transporte de calor.In this way the loss of liquid was prevented towards the outside and in addition the loss of liquids could be avoided harmful when having a liquid circulating through the element, whose function was simply that of heat transport.
Aunque esta última solución eliminó el inconveniente de la dispersión de líquidos nocivos en el medio ambiente, debido a la separación del elemento refrigerante que tiene lugar cuando la sección del circuito implicado ya ha sido vaciada de líquido, y a que el fluido, que tiene sólo la misión de transportar el calor, puede ser del tipo de baja volatilidad, persiste el problema de tener que dejar un objeto metálico: el elemento refrigerante, con tiempos de descomposición más bien largos, dentro del ataúd.Although this last solution eliminated the inconvenience of the dispersion of harmful liquids in the medium ambient, due to the separation of the cooling element that takes place when the section of the circuit involved has already been drained of liquid, and to that fluid, which has only the mission of transport heat, it can be of the low volatility type, the problem of having to leave a metallic object persists: the cooling element, with decomposition times rather long, inside the coffin.
Por otra parte, el empleo de materiales no metálicos para la fabricación del elemento plantea el problema de la baja conductividad térmica de dichos materiales y, por consiguiente, la insuficiente capacidad de enfriar eficazmente el entorno que lo rodea.On the other hand, the use of materials does not Metallic for the manufacture of the element raises the problem of the low thermal conductivity of said materials and, by consequently, the insufficient ability to effectively cool the surrounding environment.
El principal objeto de la presente invención es proponer un dispositivo refrigerante para ataúdes, según se define en la patente italiana n° 1.264.864, en el cual el elemento refrigerante destinado a quedar en el interior del ataúd consiste en un material degradable o biodegradable, resistente a las tensiones del fluido refrigerante que circula dentro de él y con una conductividad térmica suficientemente alta para enfriar el ambiente que lo rodea y mantenerlo a esa temperatura.The main object of the present invention is propose a cooling device for coffins, as defined in Italian Patent No. 1,264,864, in which the element refrigerant intended to be inside the coffin consists in a degradable or biodegradable material, resistant to tensions of the cooling fluid circulating within it and with a thermal conductivity high enough to cool the surrounding environment and keep it at that temperature.
Se descubrió con sorpresa que el principal objetivo de la presente invención se puede alcanzar utilizando un material polimérico biodegradable para la preparación del elemento refrigerante. Ese material es una mezcla de polímeros naturales y sintéticos, y tiene una conductividad térmica claramente superior a la de los polímeros no biodegradables.It was discovered with surprise that the principal objective of the present invention can be achieved using a biodegradable polymeric material for the preparation of the element refrigerant. That material is a mixture of natural polymers and synthetic, and has a thermal conductivity clearly superior to that of non-biodegradable polymers.
Aunque el elemento puede hacerse de cualquier material plástico que presente las condiciones antedichas, se ha visto que el producto Mater-BI, comercializado por la firma Novamont S.p.A., satisface todas exigencias al mismo tiempo y está formado por una mezcla debidamente tratada de polímeros sintéticos y naturales.Although the element can be made of any plastic material that presents the above conditions, has seen that the Mater-BI product, marketed by The firm Novamont S.p.A., satisfies all requirements to it time and consists of a properly treated mixture of synthetic and natural polymers.
El procedimiento para la preparación del elemento refrigerante con material biodegradable no constituye un aspecto crítico de la invención. Puede emplearse cualquier sistema de moldeo utilizado en el campo de la fabricación de plásticos, con la condición de que el producto obtenido presente suficiente espesor para asegurar la necesaria resistencia mecánica a la transmisión de calor. Una ventaja de utilizar material plástico reside en el hecho de que puede adoptar cualquier forma que resulte más adecuada para la función que debe desempeñar.The procedure for the preparation of the element refrigerant with biodegradable material does not constitute an aspect Critic of the invention. Any system of molding used in the field of plastics manufacturing, with the condition that the product obtained has sufficient thickness to ensure the necessary mechanical resistance to the transmission of hot. An advantage of using plastic material lies in the fact that you can take any form that is most appropriate for The role you must play.
El procedimiento de trabajo conocido como termoformado se ha revelado como el más adecuado para producir elementos refrigerantes según la invención.The work procedure known as thermoforming has been revealed as the most suitable to produce cooling elements according to the invention.
El fluido refrigerante que circula por la parte del circuito que comprende el elemento no debe ser un disolvente para el material biodegradable. En el caso particular de que los dos líquidos empleados para la función antedicha sean el mismo, no se dispondrán dos circuitos, sino sólo uno, por el cual circula el fluido refrigerante. En este caso, el elemento habrá de tener una estructura capaz de resistir los esfuerzos y ataques del líquido refrigerante.The coolant flowing through the part of the circuit comprising the element must not be a solvent for the biodegradable material. In the particular case that two liquids used for the above function are the same, not two circuits will be arranged, but only one, through which the coolant In this case, the element must have a structure capable of resisting the efforts and attacks of the liquid refrigerant.
La invención se comprenderá mejor y sus ventajas se pondrán mejor de manifiesto por la descripción que sigue de una realización de la invención en la cual se hará referencia a los dibujos adjuntos, que se presentan a título de ejemplo y no de limitación de la invención y en los cuales:The invention will be better understood and its advantages they will be better revealed by the following description of a embodiment of the invention in which reference will be made to the attached drawings, which are presented by way of example and not of limitation of the invention and in which:
La figura 1 muestra, de manera esquemática, una realización de un grupo que comprende un elemento refrigerante separable y biodegradable para un dispositivo refrigerador según la invención.Figure 1 shows, schematically, a realization of a group comprising a cooling element separable and biodegradable for a cooling device according to the invention.
Las figuras 2, 3 y 4 muestran algunas realizaciones de elementos refrigerantes según la invención.Figures 2, 3 and 4 show some embodiments of cooling elements according to the invention.
En la figura 1, el grupo refrigerador está constituido por tres componentes: la parte C comprende el elemento refrigerante, la parte B comporta medios para hacer circular el fluido refrigerante, y la parte A comprende el circuito con el líquido refrigerante, que se halla en intercambio térmico con el elemento B.In figure 1, the refrigerator group is consisting of three components: part C comprises the element refrigerant, part B involves means to circulate the cooling fluid, and part A comprises the circuit with the coolant, which is in thermal exchange with the item B.
El grupo refrigerante, según una realización de la invención representada en la figura 1, comprende un circuito refrigerante cerrado 30 de tipo conocido, por el cual circula un fluido de intercambio térmico a base de freon, y un segundo circuito por el cual se hace circular en estado líquido un fluido de intercambio térmico de baja temperatura de congelación y alta temperatura de ebullición, por ejemplo, glicol. Los dos circuitos están acoplados térmicamente por medio de un intercambiador de calor 31 por el que circulan los dos fluidos, refrigerante y refrigerado, preferentemente a contracorriente, por dos tubos diferentes.The cooling group, according to an embodiment of the invention represented in figure 1, comprises a circuit closed refrigerant 30 of known type, through which a Freon-based heat exchange fluid, and a second circuit through which a fluid is circulated in a liquid state Low temperature freezing and high heat exchange boiling temperature, for example, glycol. The two circuits are thermally coupled by means of a heat exchanger heat 31 through which the two fluids circulate, refrigerant and cooled, preferably countercurrent, by two tubes different.
El uso de dos circuitos distintos, y en especial un circuito refrigerante cerrado, elimina las pérdidas de fluido refrigerante que pasarían a la atmósfera.The use of two different circuits, and especially a closed refrigerant circuit eliminates fluid losses refrigerant that would pass into the atmosphere.
El segundo circuito del grupo refrigerante comprende una bomba 32 para la circulación del segundo fluido de intercambio térmico y un depósito 33 para la recogida de dicho segundo fluido, y este circuito se halla acoplado al elemento refrigerante 34 de la parte A.The second circuit of the refrigerant group it comprises a pump 32 for the circulation of the second fluid of thermal exchange and a tank 33 for the collection of said second fluid, and this circuit is coupled to the element refrigerant 34 of part A.
El elemento refrigerante 34 puede separarse del resto del circuito en correspondencia con un par de uniones 36, hechas, por ejemplo, del mismo material polimérico biodegradable que el elemento. Las uniones 36 están situadas respectivamente aguas arriba del tubo 37 de entrada de fluido y aguas abajo del tubo de salida 38 del elemento refrigerante 34.The cooling element 34 can be separated from the rest of the circuit in correspondence with a pair of junctions 36, made, for example, of the same biodegradable polymeric material that the element. The junctions 36 are located respectively waters above the fluid inlet tube 37 and downstream of the tube outlet 38 of the cooling element 34.
La bomba 32, que actúa como medio para hacer circular el fluido de intercambio térmico en el segundo circuito, es preferentemente del tipo volumétrico. Esto permite que sean bombeados tanto el fluido de intercambio térmico dentro del circuito como el aire necesario para evacuar el fluido de intercambio térmico del elemento 34, y hace posible que el fluido se recupere en el depósito 33.Pump 32, which acts as a means to make circulate the heat exchange fluid in the second circuit, It is preferably of the volumetric type. This allows them to be pumped both the heat exchange fluid inside the circuit like the air needed to evacuate the fluid from thermal exchange of element 34, and makes it possible for the fluid recover in deposit 33.
Entre el depósito 33 y la bomba 32 se dispone una válvula 39 de tres vías, aguas arriba de la última respecto a la dirección de la circulación del fluido, con objeto de vaciar el elemento 34. Mientras que dos bocas de la válvula están unidas al circuito, la tercera boca se halla en comunicación con la atmósfera, para permitir el bombeo de aire al circuito y por consiguiente extraer el fluido de intercambio térmico del elemento 34. Durante el normal funcionamiento del grupo refrigerante, las bocas que comunican con el resto del circuito están abiertas, mientras que la tercera boca, que comunica con la atmósfera, se halla cerrada.Between the tank 33 and the pump 32 there is a three-way valve 39, upstream of the last one with respect to the direction of fluid circulation, in order to empty the element 34. While two valve nozzles are attached to the circuit, the third mouth is in communication with the atmosphere, to allow the pumping of air to the circuit and by consequently extract the heat exchange fluid from the element 34. During normal operation of the refrigerant group, the mouths that communicate with the rest of the circuit are open, while the third mouth, which communicates with the atmosphere, is It is closed.
La introducción de aire en el circuito permite que se recupere una gran parte del fluido de intercambio térmico que de otro modo se perdería con el elemento refrigerante cuando se deja en el interior del ataúd en el momento de su cierre definitivo.The introduction of air into the circuit allows a large part of the heat exchange fluid is recovered that would otherwise be lost with the cooling element when leave inside the coffin at the time of its closure definitive.
Según un aspecto preferido de la presente invención, el vaciado del elemento 34 se efectúa automáticamente por medio de un dispositivo de control 40 de tipo electromecánico o electrónico. La válvula 39 es también de tipo electromecánico, por ejemplo, una válvula de solenoide accionada eléctricamente.According to a preferred aspect of the present invention, the emptying of the element 34 is carried out automatically by means of a control device 40 of the electromechanical type or electronic. The valve 39 is also electromechanical, for example, an electrically operated solenoid valve.
Antes de separar el elemento refrigerante 34, el operador envía una orden al dispositivo de control 40 por medio de la línea de conexión eléctrica 41. El dispositivo de control 40, a su vez, ordena el cierre de la válvula 39 por medio de la línea 42 de conexión eléctrica, de modo que se cierre la boca enfrentada al depósito 33 y se abra a la atmósfera la parte de circuito aguas debajo de la propia válvula.Before separating the cooling element 34, the operator sends an order to the control device 40 by means of the electrical connection line 41. The control device 40, a in turn, orders the closing of the valve 39 by means of line 42 of electrical connection, so that the mouth facing the tank 33 and the water circuit part is opened to the atmosphere under the valve itself.
Al mismo tiempo que abrir la válvula 39, el dispositivo de control 40 pone en marcha el accionamiento de la bomba 32 por medio de la línea 43 de conexión eléctrica. Esto hace que entre aire en el circuito aguas debajo de la válvula 39 y, como consecuencia, que el fluido de intercambio térmico circule por el circuito hacia el depósito de recuperación 33.At the same time as opening valve 39, the control device 40 starts the drive of the pump 32 by means of electrical connection line 43. This does that air enters the circuit downstream of valve 39 and, as consequently, that the heat exchange fluid circulates through the circuit to the recovery tank 33.
Cuando se llega a un determinado grado de vaciado del elemento, un sensor apropiado (por ejemplo, un sensor de sobrecarga térmica) desconecta la bomba. Por consiguiente, el elemento 34 puede desacoplarse de la parte reutilizable del grupo refrigerante sin pérdidas apreciables del fluido de intercambio térmico. También pueden utilizarse grupos enfriadores que no contengan un doble circuito por el que se haga circular dos líquidos (respectivamente, refrigerantes y fluidos de intercambio térmico), sino con sólo el líquido refrigerante circulando. En tal caso, el elemento enfriador deberá escogerse de modo que resista la acción disolvente del refrigerante líquido y los esfuerzos debidos a la compresión y expansión del refrigerante líquido.When a certain degree of emptying is reached of the element, an appropriate sensor (for example, a sensor of thermal overload) disconnects the pump. Therefore, the item 34 can be decoupled from the reusable part of the group refrigerant without appreciable losses of the exchange fluid thermal. Cooling groups can also be used that do not contain a double circuit through which two are circulated liquids (respectively, refrigerants and exchange fluids thermal), but with only the coolant circulating. In that In this case, the cooling element must be chosen so that it resists solvent action of the liquid refrigerant and the efforts due to the compression and expansion of the liquid refrigerant.
Las figuras 2, 3 y 4 muestran algunas realizaciones del elemento enfriador obtenido con polímeros biodegradables.Figures 2, 3 and 4 show some embodiments of the cooling element obtained with polymers biodegradable
La figura 2 representa un serpentín de un elemento enfriador según la invención. La sección circular permite que los restos sean enfriados eficazmente siguiendo el perfil del cuerpo. El polímero biodegradable que constituye el elemento enfriador, dada su flexibilidad, permite que el serpentín resista cualesquiera deformaciones pequeñas que sean necesarias, incluso irreversibles, para realizar mejor su función enfriadora.Figure 2 represents a coil of a cooling element according to the invention. The circular section allows that the remains be effectively cooled following the profile of the Body. The biodegradable polymer that constitutes the element Cooler, given its flexibility, allows the coil to resist any small deformations that are necessary, even irreversible, to better perform its cooling function.
