Description
Aparato de refrigeración de varios compartimentos para el almacenamiento de alimentos frescos a diferentes temperaturas Multi-compartment refrigeration device for storing fresh food at different temperatures
La presente invención se refiere a aparatos de refrigeración, en particular a refrigeradores, por ejemplo para uso doméstico. En particular, la presente invención se refiere a refrigeradores provistos de dos (o más) subcompartimentos para alimentos frescos, diseñados para funcionar en diferentes gamas de temperaturas. The present invention relates to refrigeration appliances, in particular refrigerators, for example for domestic use. In particular, the present invention relates to refrigerators provided with two (or more) sub-compartments for fresh foods, designed to operate in different temperature ranges.
Es de sobra sabido que los alimentos frescos tienen que ser almacenados adecuadamente para que no se estropeen y conserven sus cualidades nutricionales. También es de sobra sabido que cada alimento tiene diferentes requisitos de almacenamiento; a modo de ejemplo las verduras pueden conservarse mejor y más tiempo si se mantienen a un temperatura de aproximadamente cero grados Celsius, mientras que el queso se puede almacenar durante períodos de tiempo relativamente largos a temperaturas cercanas a la temperatura ambiente (por lo menos en un clima frío o templado). It is well known that fresh foods have to be stored properly so that they do not spoil and retain their nutritional qualities. It is also well known that each food has different storage requirements; by way of example, vegetables can be preserved better and longer if they are kept at a temperature of approximately zero degrees Celsius, while cheese can be stored for relatively long periods of time at temperatures close to room temperature (at least in a cold or temperate weather).
También se sabe que la mayoría de los alimentos pierden, en parte o totalmente, sus cualidades nutricionales si se congelan (un ejemplo son, de nuevo, las verduras) limitándose así la posibilidad de almacenarlos en un congelador. Por lo tanto, los alimentos deben ser almacenados en un compartimento de alimentos frescos de un refrigerador. It is also known that most foods lose, partially or totally, their nutritional qualities if they are frozen (an example are, again, vegetables) thus limiting the possibility of storing them in a freezer. Therefore, food must be stored in a fresh food compartment of a refrigerator.
Se han desarrollado refrigeradores con dos (o más) compartimentos para alimentos frescos que funcionan a diferente temperatura, consiguiendo una capacidad de almacenamiento mejorada, gracias a las diferentes gamas de temperatura de almacenamiento, lo que permite almacenar diferentes tipos de alimentos de una manera óptima. Refrigerators have been developed with two (or more) compartments for fresh foods that operate at different temperatures, achieving an improved storage capacity, thanks to the different ranges of storage temperature, which allows to store different types of food in an optimal way.
Se han desarrollado varios tipos de refrigerador con compartimentos para alimentos frescos mantenidos a diferentes gamas de temperatura. Por lo general, los refrigeradores con dos compartimentos para alimentos frescos tienen un compartimento que funciona en la gama típica de temperaturas de los refrigeradores (por ejemplo, desde +3°C hasta +7°C), y otro compartimento que funciona en una gama inferior de temperaturas, típicamente de cerca de cero grados Celsius, típicamente de 0°C a +3°C. Several types of refrigerators have been developed with compartments for fresh food kept at different temperature ranges. Generally, refrigerators with two compartments for fresh food have a compartment that works in the typical range of refrigerator temperatures (for example, from + 3 ° C to + 7 ° C), and another compartment that works in a range lower temperatures, typically near zero degrees Celsius, typically from 0 ° C to + 3 ° C.
Una manera fácil de obtener compartimentos para alimentos frescos que funcionen en diferentes gamas de temperatura consiste en proporcionar un evaporador para cada compartimento. Esta solución, aunque garantiza un buen rendimiento, aumenta el coste del refrigerador hasta un grado no competitivo para el mercado. Otra solución consiste en extraer aire frío de un congelador previsto en el refrigerador (cuando el refrigerador forma parte integral de un congelador en la denominada estructura de refrigerador combinado) y alimentarlo al compartimento de alimentos frescos de baja temperatura. Esta solución, usando aire a temperaturas muy bajas (típicamente de -18°C a -27°C), puede dañar los alimentos almacenados si el refrigerador no está diseñado y funciona correctamente. Otra solución puede consistir en usar un evaporador compartido con el otro compartimento o compartimentos). An easy way to get compartments for fresh foods that work in different temperature ranges is to provide an evaporator for each compartment. This solution, while guaranteeing good performance, increases the cost of the refrigerator to a degree that is not competitive for the market. Another solution is to extract cold air from a freezer provided in the refrigerator (when the refrigerator is an integral part of a freezer in the so-called combined refrigerator structure) and feed it to the low temperature fresh food compartment. This solution, using air at very low temperatures (typically from -18 ° C to -27 ° C), can damage stored food if the refrigerator is not designed and works properly. Another solution may be to use an evaporator shared with the other compartment or compartments).

En realizaciones alternativas de la invención, no mostradas, el panel que separa los subcompartimentos de alimentos frescos primero y segundo puede tener una forma diferente, por ejemplo, puede ser plano, y el ventilador secundario puede montarse horizontalmente sobre el mismo. With reference to the drawings, a front view of a refrigerator 100, without doors, in accordance with an embodiment of the present invention is shown in Figure 1. In particular, the refrigerator 100 is a refrigerator called a combined refrigerator, being provided with a freezer compartment 105 in the same housing 110 comprising a fresh food compartment 115. The fresh food compartment 115 is divided into a first fresh food sub-compartment 120 and in a second sub-compartment of fresh foods 125, separated by a panel 130, preferably capable of providing thermal insulation. A main fan 135 is provided in the first fresh food sub-compartment 120, preferably, but not limited to, near the top of a rear wall 140. Integrated in the rear wall 140 and in correspondence with the main fan 135, it is provided with an evaporator 145 (shown with a broken line). Evaporator 145 extends most of the height of the first fresh food sub-compartment 120 vertically and has a bottom 150 located in correspondence with the second fresh food sub-compartment 125. A secondary fan 155 is associated with panel 130. Preferably, the panel 130 has a substantially stepped shape, with a first horizontal part 130a, of prevalent extension, a second horizontal part 130b, closer to the rear wall 140 and at a higher level with respect to the first panel part 130a, and a vertical part 130c that joins the first and second horizontal parts 130a and 130b. The secondary fan 155 is mounted on the panel 130 in correspondence with its vertical part 130c. In alternative embodiments of the invention, not shown, the panel separating the first and second fresh food sub-compartments may have a different shape, for example, it may be flat, and the secondary fan may be mounted horizontally thereon.
La figura 2 muestra esquemáticamente una vista en sección (por un eje II-II mostrado en la figura 1) del refrigerador 100 de la figura 1. Como puede verse, un panel posterior 160 define un espacio intermedio 165 con la pared trasera 140 y separa el evaporador 145 del compartimento de alimentos frescos 115. El ventilador principal 135 atraviesa el panel posterior 160 y llega al espacio intermedio 165. Adicionalmente, el panel posterior 160 tiene una anchura menor que la pared trasera 140 permitiendo que unas aberturas laterales 170 se desplacen a lo largo de los lados verticales de la pared trasera 140 del compartimento de alimentos frescos 115 una longitud preferentemente, aunque no de manera limitativa, correspondiente a la longitud del evaporador 145. El panel 160 se extiende, en la dirección vertical, por casi toda la altura del primer subcompartimento de alimentos frescos 120, y también por una parte superior del segundo subcompartimento de alimentos frescos 125. Por lo tanto, una parte principal de las aberturas laterales 170 se extiende en el primer subcompartimento de alimentos frescos 120 y, una parte más corta de las mismas, en el segundo subcompartimento de alimentos frescos 125. Figure 2 schematically shows a sectional view (along an axis II-II shown in Figure 1) of the refrigerator 100 of Figure 1. As can be seen, a rear panel 160 defines an intermediate space 165 with the rear wall 140 and separates the evaporator 145 of the fresh food compartment 115. The main fan 135 crosses the rear panel 160 and reaches the intermediate space 165. Additionally, the rear panel 160 is smaller than the rear wall 140 allowing lateral openings 170 to travel to along the vertical sides of the rear wall 140 of the fresh food compartment 115 a length preferably, but not limited to, the length of the evaporator 145. The panel 160 extends, in the vertical direction, for almost the entire height of the first sub-compartment of fresh food 120, and also by a top of the second sub-compartment of fresh food 125. Therefore, a main part of the lateral openings 170 extends in the first fresh food sub-compartment 120 and, a shorter part thereof, in the second fresh food sub-compartment 125.
Otra abertura 175 está definida en el extremo inferior del panel posterior 160, todavía entre el panel 160 y la pared trasera 140, hasta el segundo subcompartimento de alimentos frescos 125. Gracias a las aberturas laterales 170 y a la abertura inferior 175, se crea comunicación fluida entre el evaporador 145 y el compartimento de alimentos frescos 115. La abertura 175 está preferiblemente situada delante del ventilador secundario 155. Another opening 175 is defined at the lower end of the rear panel 160, still between the panel 160 and the rear wall 140, up to the second sub-compartment of fresh foods 125. Thanks to the side openings 170 and the lower opening 175, fluid communication is created between the evaporator 145 and the fresh food compartment 115. The opening 175 is preferably located in front of the secondary fan 155.
En otras realizaciones de la invención, no mostradas, el panel posterior 160 puede ser sustituido por paneles posteriores alternativos provistos de agujeros o de una estructura de tipo rejilla para crear una comunicación fluida entre el evaporador y el compartimento de alimentos frescos 115. In other embodiments of the invention, not shown, the rear panel 160 may be replaced by alternative rear panels provided with holes or a grid-like structure to create a fluid communication between the evaporator and the fresh food compartment 115.
Por otro lado, la primera parte horizontal 130a del panel 130 tiene una longitud tal que deja un hueco frontal 177 entre una puerta frontal 178 del compartimento de alimentos frescos 115 y el panel 130 en sí. Además, o como alternativa, un hueco posterior 179 puede estar previsto entre el panel posterior 160 y la segunda parte horizontal 130b del panel 130. Además, se pueden proporcionar aberturas adicionales (no mostradas) en las partes horizontales primera y segunda 130a, 130b así como en la parte vertical 130c del panel 130. On the other hand, the first horizontal part 130a of the panel 130 has a length such that it leaves a front gap 177 between a front door 178 of the fresh food compartment 115 and the panel 130 itself. In addition, or as an alternative, a rear opening 179 may be provided between the rear panel 160 and the second horizontal part 130b of the panel 130. In addition, additional openings (not shown) can be provided in the first and second horizontal parts 130a, 130b as well as in the vertical part 130c of the panel 130.
El funcionamiento del refrigerador 100 lo controla una unidad de control de refrigerador 180. Un primer sensor de temperatura 185 y un segundo sensor de temperatura 190 pueden estar previstos en el primer subcompartimento de alimentos frescos 120 y en el segundo subcompartimento de alimentos frescos 125, respectivamente, para permitir que la unidad de control de refrigerador 180 supervise las temperaturas en ambos subcompartimentos para alimentos frescos 120 y 125. The operation of the refrigerator 100 is controlled by a refrigerator control unit 180. A first temperature sensor 185 and a second temperature sensor 190 may be provided in the first fresh food sub-compartment 120 and in the second fresh food sub-compartment 125, respectively. , to allow the refrigerator control unit 180 to monitor temperatures in both subcompartments for fresh foods 120 and 125.
Con referencia ahora tanto a la figura 1 como a la figura 2, se describirá el funcionamiento del refrigerador 100. El ventilador principal 135 y el evaporador 145 son accionados por la unidad de control de refrigerador 180 para mantener el primer subcompartimento de alimentos frescos 120 por debajo de una temperatura máxima prevista T, normalmente seleccionada por un usuario; con más detalle, la temperatura máxima prevista T se puede ajustar típicamente, por ejemplo, con un termostato conocido de sobra en el estado de la técnica (no mostrado en las figuras) en una gama de temperaturas que va de +3°C a +7ºC. Durante su funcionamiento, el ventilador principal 135 aspira aire del primer subcompartimento de alimentos frescos 120 y lo insufla al espacio intermedio 165, donde es enfriado por el evaporador Referring now to both Figure 1 and Figure 2, the operation of the refrigerator 100 will be described. The main fan 135 and the evaporator 145 are driven by the refrigerator control unit 180 to keep the first sub-compartment of fresh foods 120 by below a maximum expected temperature T, normally selected by a user; in more detail, the maximum expected temperature T can typically be adjusted, for example, with a thermostat known in the prior art (not shown in the figures) in a temperature range from + 3 ° C to + 7ºC. During operation, the main fan 135 draws air from the first sub-compartment of fresh food 120 and blows it into intermediate space 165, where it is cooled by the evaporator
145. Parte del aire enfriado vuelve después al primer subcompartimento de alimentos frescos 120 a través de las aberturas 170 que se extienden en el primer subcompartimento de alimentos frescos 120 y otra parte llega al segundo subcompartimento de alimentos frescos 125 a través de la abertura 175 y las aberturas 170 que se extienden en el segundo subcompartimento de alimentos frescos 125. De esta manera, se hace descender la temperatura del primer 145. Part of the cooled air then returns to the first fresh food sub-compartment 120 through openings 170 that extend into the first fresh food sub-compartment 120 and another part reaches the second fresh food sub-compartment 125 through opening 175 and the openings 170 extending in the second sub-compartment of fresh foods 125. In this way, the temperature of the first is lowered
subcompartimento de alimentos frescos 120 hasta la temperatura máxima prevista T seleccionada por el usuario. Una vez que se alcanza esta condición, el evaporador 145 y el ventilador principal 135 se apagan. fresh food sub-compartment 120 up to the maximum expected temperature T selected by the user. Once this condition is reached, evaporator 145 and main fan 135 are turned off.
Al mismo tiempo, se hace descender la temperatura del segundo subcompartimento de alimentos frescos 125. En particular, la temperatura del segundo subcompartimento de alimentos frescos 125 desciende a una temperatura inferior a la del primer subcompartimento de alimentos frescos 120. Con más detalle, gracias a la tendencia a la estratificación del aire (si el aire frío es más denso, es más pesado, y por tanto permanece en una posición más baja que el aire más caliente) el aire frío tiende a permanecer confinado en el segundo subcompartimento de alimentos frescos 125; además, el aire frío que hay en la parte inferior del subcompartimento de alimentos frescos 120 tiende a caer en el segundo subcompartimento de alimentos frescos 125 a través de los huecos frontal y posterior 177,179. At the same time, the temperature of the second sub-compartment of fresh foods 125 is lowered. In particular, the temperature of the second sub-compartment of fresh foods 125 falls below a temperature below that of the first sub-compartment of fresh foods 120. In more detail, thanks to the tendency to stratify the air (if the cold air is denser, it is heavier, and therefore remains in a lower position than the warmer air) the cold air tends to remain confined in the second sub-compartment of fresh food 125 ; in addition, the cold air in the lower part of the fresh food sub-compartment 120 tends to fall into the second fresh food sub-compartment 125 through the front and rear gaps 177,179.
Además, debido al diseño estructural del segundo subcompartimento de alimentos frescos 125 (que es más pequeño que el primer subcompartimento de alimentos frescos 120 y está aislado térmicamente del mismo mediante el panel 130, este último comprendiendo o estando hecho preferiblemente de al menos un material altamente aislante), cuando se abre la puerta del refrigerador, el intercambio de calor con el ambiente exterior es menor en comparación con el que tiene lugar con respecto al primer subcompartimento de alimentos frescos 120. In addition, due to the structural design of the second fresh food sub-compartment 125 (which is smaller than the first fresh food sub-compartment 120 and is thermally insulated therefrom by panel 130, the latter comprising or preferably being made of at least one material highly insulator), when the refrigerator door is opened, the heat exchange with the outside environment is less compared to that which takes place with respect to the first sub-compartment of fresh food 120.
Además, el segundo subcompartimento de alimentos frescos 125 se encuentra por encima del compartimento congelador 105, el cual está a una temperatura muy baja, por lo que no entra calor en el subcompartimento 125 desde su parte inferior. In addition, the second sub-compartment of fresh foods 125 is located above the freezer compartment 105, which is at a very low temperature, so that no heat enters sub-compartment 125 from its bottom.
Sin embargo, el aire que llega al segundo subcompartimento de alimentos frescos 125 a través de la abertura 175 y la parte inferior de las aberturas 170 es más frío que el aire que llega al primer subcompartimento de alimentos frescos 120 a través de la parte superior de las aberturas 170 porque el primero se desplaza a lo largo de todo el evaporador 145 antes de salir del espacio intermedio 165. Incluso aunque el evaporador 145 y el ventilador principal 135 estén apagados, debido a la tendencia a la estratificación antes mencionada, el aire más frío (como el evaporador se mantiene a una temperatura baja durante un período relativamente largo después de que se apaga) tiende a circular hasta el segundo subcompartimento de alimentos frescos 125 a través de la abertura 175 y a través de las aberturas 170 que se extienden en la parte inferior del panel posterior 160. However, the air that reaches the second sub-compartment of fresh food 125 through the opening 175 and the bottom of the openings 170 is colder than the air that reaches the first sub-compartment of fresh food 120 through the upper part of the openings 170 because the first one travels along the entire evaporator 145 before leaving the intermediate space 165. Even if the evaporator 145 and the main fan 135 are turned off, due to the aforementioned tendency to stratification, the air more Cold (as the evaporator is kept at a low temperature for a relatively long period after it is turned off) it tends to circulate to the second sub-compartment of fresh food 125 through the opening 175 and through the openings 170 that extend into the bottom of rear panel 160.
El panel 130 impide que el aire procedente de los dos subcompartimentos para alimentos frescos 120 y 125 se mezcle hasta el punto de llegar a una temperatura común (más alta para el segundo subcompartimento de alimentos frescos 125 y más baja para el primer subcompartimento de alimentos frescos 120 que los valores seleccionados). Panel 130 prevents the air from the two sub-compartments for fresh foods 120 and 125 from mixing to the point of reaching a common temperature (higher for the second sub-compartment of fresh foods 125 and lower for the first sub-compartment of fresh foods 120 than the selected values).
La unidad de control de refrigerador 180 también puede accionar el ventilador principal 135 y el evaporador 145 periódicamente (por ejemplo, usando ciclos de activación de una duración predeterminada con una frecuencia que depende de la temperatura seleccionada por el usuario), o mediante la supervisión de la temperatura en el primer subcompartimento de alimentos frescos 120 con el primer sensor de temperatura 185 dispuesto en su interior (es decir, accionando el evaporador 145 y el ventilador principal 135 siempre que se detecte una temperatura que esté por encima de la temperatura máxima prevista T). The refrigerator control unit 180 can also operate the main fan 135 and the evaporator 145 periodically (for example, using activation cycles of a predetermined duration with a frequency that depends on the temperature selected by the user), or by monitoring the temperature in the first sub-compartment of fresh food 120 with the first temperature sensor 185 disposed therein (that is, by operating the evaporator 145 and the main fan 135 whenever a temperature is detected that is above the maximum expected temperature T ).
El ventilador secundario 155 es accionado por la unidad de control de refrigerador 180 para mantener la temperatura del segundo subcompartimento de alimentos frescos 125 dentro de una gama de temperaturas prevista y, en particular, por encima de una temperatura mínima predeterminada Tm; con más detalle, la temperatura mínima Tm está normalmente comprendida en una gama de seguridad alimentaria de temperaturas que van de 0°C a +3°C. El ventilador secundario 155 aspira aire del primer subcompartimento de alimentos frescos 120 y lo insufla al segundo subcompartimento de alimentos frescos 125. Dicho aire tiene una temperatura más alta que la del aire del segundo subcompartimento de alimentos frescos 125, por las razones expuestas anteriormente; por lo tanto, el insuflado de aire del primer subcompartimento de alimentos frescos 120 al segundo subcompartimento de alimentos frescos 125 permite elevar la temperatura del segundo subcompartimento de alimentos frescos 125 (hasta el punto que dependa del tiempo de activación del ventilador secundario 155). Además, el flujo de aire generado por el ventilador secundario 155 choca con un flujo de aire opuesto generado por el accionamiento del ventilador principal 135 y entra en el segundo subcompartimento de alimentos frescos 125 a través de las aberturas 170 (en la parte inferior del panel 160) y la abertura 175. De manera ventajosa, el ventilador secundario 155 se puede diseñar para generar el flujo de aire de manera que al menos detenga en parte o totalmente el flujo de aire opuesto que viene del espacio intermedio 165, evitando que enfríe más el segundo subcompartimento de alimentos frescos 125, hasta que su temperatura se haya elevado por encima de la temperatura mínima. En tal estado de funcionamiento (ambos ventiladores 135 y 155 encendidos) el aire sale del segundo subcompartimento de alimentos frescos 125 a través de los huecos frontal y posterior 177, 179. Por el contrario, cuando el ventilador principal 135 está apagado y el ventilador secundario 155 se acciona, el aire circula del segundo subcompartimento de alimentos frescos 125 al primer subcompartimento de alimentos frescos 120 a través de los huecos frontal y posterior 177, 179 y también a través de las aberturas 170, después de haber sido insuflado hacia atrás por el ventilador secundario 155 al espacio intermedio 165 a través de la abertura 175. The secondary fan 155 is operated by the refrigerator control unit 180 to maintain the temperature of the second sub-compartment of fresh foods 125 within a predicted temperature range and, in particular, above a predetermined minimum temperature Tm; In more detail, the minimum temperature Tm is normally in a range of food safety temperatures ranging from 0 ° C to + 3 ° C. The secondary fan 155 draws air from the first fresh food sub-compartment 120 and blows it into the second fresh food sub-compartment 125. Said air has a higher temperature than the air of the second fresh food sub-compartment 125, for the reasons set forth above; therefore, the insufflation of air from the first fresh food sub-compartment 120 to the second fresh food sub-compartment 125 makes it possible to raise the temperature of the second fresh food sub-compartment 125 (to the extent that it depends on the activation time of the secondary fan 155). In addition, the air flow generated by the secondary fan 155 collides with an opposite air flow generated by the drive of the main fan 135 and enters the second sub-compartment of fresh foods 125 through the openings 170 (at the bottom of the panel 160) and the opening 175. Advantageously, the secondary fan 155 can be designed to generate the air flow so as to at least partially or totally stop the opposite air flow coming from the intermediate space 165, preventing it from cooling more the second sub-compartment of fresh foods 125, until its temperature has risen above the minimum temperature. In such a state of operation (both fans 135 and 155 on) the air exits the second sub-compartment of fresh foods 125 through the front and rear holes 177, 179. On the contrary, when the main fan 135 is off and the secondary fan 155 is activated, the air circulates from the second sub-compartment of fresh food 125 to the first sub-compartment of fresh food 120 through the front and rear gaps 177, 179 and also through the openings 170, after having been blown back by the secondary fan 155 to intermediate space 165 through opening 175.
La unidad de control puede accionar el ventilador secundario 155 siempre que una temperatura igual a, o inferior a la temperatura mínima Tm sea detecta por el segundo sensor de temperatura 190 dispuesto en el interior del segundo subcompartimento de alimentos frescos 125. The control unit can operate the secondary fan 155 provided that a temperature equal to, or less than the minimum temperature Tm is detected by the second temperature sensor 190 disposed inside the second sub-compartment of fresh foods 125.
Alternativamente, el segundo subcompartimento de alimentos frescos 125 está diseñado para tener una temperatura Alternatively, the second fresh food subcompartment 125 is designed to have a temperature
5 inferior a la temperatura máxima prevista T del primer subcompartimento de alimentos frescos 120 de una diferencia de temperatura fija ΔT (por ejemplo, 4°C). Por lo tanto, el ventilador secundario se puede activar periódicamente mediante la unidad de control 180 (es decir, usando ciclos de activación de ventilador de una duración predeterminada con una frecuencia que dependa de la temperatura máxima prevista T) para evitar que la temperatura del segundo subcompartimento de alimentos frescos 125 caiga por debajo de 0°C, sólo cuando la temperatura máxima prevista T del 5 lower than the expected maximum temperature T of the first fresh food sub-compartment 120 of a fixed temperature difference ΔT (for example, 4 ° C). Therefore, the secondary fan can be periodically activated by the control unit 180 (ie using fan activation cycles of a predetermined duration with a frequency that depends on the maximum expected temperature T) to prevent the second temperature fresh food subcompartment 125 falls below 0 ° C, only when the maximum expected temperature T of the
10 primer subcompartimento de alimentos frescos 120 sea establecida por el usuario en valores relativamente bajos (por ejemplo, entre +3 y +4°C). Por ejemplo, cuando la temperatura máxima prevista T sea establecida entre +7 y +5°C, la temperatura del segundo subcompartimento de alimentos frescos 125 permanecerá en la gama de entre +3 y +1°C, por lo que el ventilador secundario 155 estará siempre apagado. Por el contrario, cuando la temperatura máxima prevista T se establezca entre +3 y +4ºC, la temperatura del segundo subcompartimento de alimentos frescos 125 podría The first sub-compartment of fresh foods 120 is set by the user at relatively low values (for example, between +3 and + 4 ° C). For example, when the maximum expected temperature T is set between +7 and + 5 ° C, the temperature of the second sub-compartment of fresh foods 125 will remain in the range between +3 and + 1 ° C, so the secondary fan 155 It will always be off. On the contrary, when the maximum expected temperature T is set between +3 and + 4 ° C, the temperature of the second sub-compartment of fresh foods 125 could
15 descender en la gama de entre -1 y 0°C, por lo que el ventilador secundario 155 será accionado periódicamente para mantenerla por encima de 0°C. Se debe entender que en este caso no se necesita el segundo sensor de temperatura 190, el cableado relacionado y los sistemas de circuito correspondientes en la unidad de control 180 para controlar dicho segundo sensor de temperatura 190, derivando esto en una reducción de costes. 15 descend in the range between -1 and 0 ° C, so secondary fan 155 will be periodically operated to keep it above 0 ° C. It should be understood that in this case the second temperature sensor 190, the related wiring and the corresponding circuit systems in the control unit 180 are not needed to control said second temperature sensor 190, resulting in a cost reduction.
