Description
Máquina frigorifica polibárica de absorción Polyhydric absorption refrigeration machine
La invención se encuadra en el sector técnico de la energía, más concretamente en el de las máquinas frigoríficas. The invention falls within the technical sector of energy, more specifically in that of refrigeration machines.
Dada la actual preocupación por el desarrollo sostenible de la sociedad, el ahorro energético es un pilar fundamental del mismo. Given the current concern for the sustainable development of society, energy saving is a fundamental pillar of it.
El desarrollo constante de las energías renovables, como la solar y el empleo cada vez mayor del aire acondicionado, hacen necesario el desarrollo de un sistema que permita ahorrar gran parte de la energía no renovable que estos aparatos consumen en la climatización de locales y viviendas. The constant development of renewable energies, such as solar and the increasing use of air conditioning, make it necessary to develop a system that saves much of the non-renewable energy that these devices consume in the air conditioning of premises and homes.
La presente invención trata de una máquina frigorífica de absorción basada en el modelo clásico de Platen-Munters. Una máquina de este tipo se conoce a partir del documento CH-A-558 922. En este caso, se prevé un generador designado como hornillo, que se une con un condensador a través de una tubería de evaporación. El refrigerante licuado en este condensador fluye al evaporador dispuesto a continuación. La salida de este evaporador se une a través de un intercambiador de calor con un serpentín del absorbedor que desemboca en el recipiente del absorbedor. La salida de este recipiente del absorbedor se conduce hasta el hornillo a través de un intercambiador de calor de la disolución. The present invention relates to an absorption refrigeration machine based on the classic Platen-Munters model. A machine of this type is known from document CH-A-558 922. In this case, a generator designated as a stove is provided, which joins a condenser through an evaporation pipe. The liquid refrigerant in this condenser flows to the evaporator provided below. The outlet of this evaporator is connected through a heat exchanger with an absorber coil that flows into the absorber vessel. The outlet of this absorber vessel is conducted to the stove through a heat exchanger of the solution.
Para el funcionamiento de una máquina de este tipo, se requiere una fuente de calor de temperatura mayor de 100 oC. Por lo que no resultan adecuadas fuentes de inferiores temperaturas como, por ejemplo, la solar térmica de baja temperatura. For the operation of such a machine, a heat source with a temperature greater than 100 oC is required. Therefore, sources of lower temperatures are not suitable, such as the low temperature thermal solar.
El objetivo de la invención es realizar una máquina frigorífica de absorción que, con una fuente de baja temperatura, alcance una alta eficiencia. The objective of the invention is to produce an absorption refrigeration machine that, with a low temperature source, achieves high efficiency.
Esto se consigue, conforme a la invención, gracias a un sistema de regulación de la presión, a la que funciona la máquina, de modo que la temperatura de ebullición del refrigerante sea 10 oC superior a temperatura ambiente. Lo que proporciona un adecuado gradiente térmico entre el condensador y el medio exterior, a la vez que aumentamos la eficiencia de la misma. La temperatura de ebullición del refrigerante y la presión a la que debemos cargar la máquina frigorífica con el gas inerte están relacionadas mediante la ecuación de ClausiusClapeyron: This is achieved, according to the invention, thanks to a pressure regulation system, to which the machine operates, so that the boiling temperature of the coolant is 10 ° C higher than room temperature. This provides an adequate thermal gradient between the condenser and the external environment, while increasing its efficiency. The boiling temperature of the refrigerant and the pressure at which we must load the refrigerating machine with the inert gas are related by the ClausiusClapeyron equation:
dP/P =(~Hvaporización/RT2)dT dP / P = (~ Hvaporization / RT2) dT
Como vamos a trabajar con un intervalo de temperaturas lejano a la temperatura crítica del refrigerante, véase la Fig. 3, podemos hacer la aproximación ~Hvaporización =cte. Integrando: As we are going to work with a temperature range far from the critical temperature of the refrigerant, see Fig. 3, we can make the approximation ~ Hvaporization = cte. Integrating:
In(P/Po) = (~Hvaporización/R)(1ITo-1IT) In (P / Po) = (~ Hvaporization / R) (1ITo-1IT)
que es la relación que utilizaremos para obtener la presión de trabajo de la máquina frigorífica dependiendo de la temperatura del medio exterior. A continuación se explica la invención a partir de los ejemplos de realización, en los que se muestran: which is the ratio that we will use to obtain the working pressure of the refrigerating machine depending on the temperature of the outside environment. The invention is explained in the following from the examples of embodiment, in which are shown:

La máquina de absorción descrita a continuación funciona en su mayor parte como el sistema clásico de Platen y Munters que está suficientemente documentado. The absorption machine described below works mostly as the classic Platen and Munters system that is sufficiently documented.
Para una mejor comprensión, la invención se explica a partir de un ejemplo de realización en el que el disolvente se compone de CH30H, el gas inerte de H2 y el refrigerante de NH3. Dentro del marco de la invención también pueden usarse otros disolventes, gases inertes y refrigerantes adecuados. For a better understanding, the invention is explained from an exemplary embodiment in which the solvent is composed of CH30H, the inert gas of H2 and the refrigerant of NH3. Other suitable solvents, inert gases and refrigerants can also be used within the scope of the invention.
El empleo de CH30H como absorbente del NH3 redunda en una temperatura más baja de funcionamiento del generador, así como de la posibilidad de prescindir del rectificador, necesario en las máquinas frigoríficas que tienen como absorbente el agua. Esto es posible gracias al bajo punto de fusión del metanol que es de -97,16 oC a 1 atm, lo que impide la formación de hielo en el evaporador y la obstrucción del mismo. The use of CH30H as an NH3 absorber results in a lower operating temperature of the generator, as well as the possibility of dispensing with the rectifier, necessary in refrigerating machines that have water as an absorbent. This is possible thanks to the low melting point of methanol which is -97.16 oC at 1 atm, which prevents the formation of ice in the evaporator and its obstruction.
En este ejemplo de realización empleamos metanol como absorbente y por lo tanto prescindimos del rectificador, lo que conlleva una mejora del COP de la máquina frigorífica. De este modo podemos aislar todo el generador, hasta la entrada en el condensador, con un material adiabático y limitar las pérdidas de calor al mínimo en el mismo. In this exemplary embodiment, we use methanol as an absorbent and therefore dispense with the rectifier, which implies an improvement in the COP of the refrigerating machine. In this way we can isolate the entire generator, until the entry into the condenser, with an adiabatic material and limit the heat losses to a minimum in it.
La máquina frigorífica de absorción de la Fig. 1 comprende un generador (1) para la evaporación de NH3 disuelto en CH30H con un serpentín (2) recubierto de un material aislante del calor (3), que contiene un fluido caloportador (4) proveniente de una fuente de baja temperatura, el cual cede calor en el generador (1) Y retorna unos grados más frío. Un condensador (6) en el que se licua el vapor de NH3 (5), de modo que este fluye líquido a través de un tubo (7) hasta el evaporador (8), por el que circula un gas seco, en este caso hidrógeno (9). Esto provoca la evaporación del amoniaco y como consecuencia el enfriamiento del evaporador (8) que, en el ejemplo de realización, está en contacto con un circuito cerrado (10) el cual contiene un fluido caloportador, empleado para refrigerar el espacio a acondicionar. Este hecho constituye el auténtico proceso de refrigeración de la máquina. La mezcla de amoniaco e hidrógeno (11) resultante, más pesada, cae por gravedad hacia el tanque del absorbedor (12), gracias a lo cual el circuito del hidrógeno se mantiene en marcha. A continuación, la mezcla de gases sigue fluyendo hacia el absorbedor (13) donde se encuentra con la solución empobrecida (14), proveniente del generador (1), de modo que la disolución va enriqueciéndose a medida que cae hacia el tanque del absorbedor (12). Una vez allí la disolución rica en amoniaco (15) es conducida a través de un intercambiador de calor (16) de nuevo al generador (1) iniciándose de nuevo el proceso. El hidrógeno (9) nuevamente seco, asciende del absorbedor y se encuentra con una derivación (17) que lleva al regulador de presión (18) y continúa hacia el evaporador (8) completando así el circuito. The refrigeration absorption machine of Fig. 1 comprises a generator (1) for the evaporation of NH3 dissolved in CH30H with a coil (2) coated with a heat insulating material (3), which contains a heat transfer fluid (4) from from a low temperature source, which yields heat in the generator (1) and returns a few degrees cooler. A condenser (6) in which the vapor of NH3 (5) is liquefied, so that it flows liquid through a tube (7) to the evaporator (8), through which a dry gas circulates, in this case hydrogen (9). This causes the evaporation of the ammonia and as a consequence the cooling of the evaporator (8) which, in the exemplary embodiment, is in contact with a closed circuit (10) which contains a heat transfer fluid, used to cool the space to be conditioned. This fact constitutes the authentic cooling process of the machine. The resulting heavier ammonia and hydrogen mixture (11) falls by gravity into the absorber tank (12), whereby the hydrogen circuit is kept running. Next, the gas mixture continues to flow towards the absorber (13) where it meets the depleted solution (14), coming from the generator (1), so that the solution is getting richer as it falls into the absorber tank ( 12). Once there, the ammonia-rich solution (15) is conducted through a heat exchanger (16) back to the generator (1) and the process starts again. The hydrogen (9) again dried, rises from the absorber and meets a branch (17) that leads to the pressure regulator (18) and continues to the evaporator (8) thus completing the circuit.
La Fig. 2 muestra en una forma esquemática un regulador de presión. El depósito de reserva (19) se carga con el gas inerte a la mínima presión de trabajo de la máquina frigorífica. Si queremos trabajar con una temperatura mínima ambiental de 25 oC, por ejemplo en el caso de acondicionar una vivienda, tenemos que cargar la máquina a 13,42 atm para que la temperatura de ebullición del amoniaco sea de 35 oC. Si la temperatura ambiente varía es detectada por la sonda (24). Como la temperatura de ebullición del amoniaco es función de la presión de la Fig. 2 shows in a schematic form a pressure regulator. The reserve tank (19) is loaded with inert gas at the minimum working pressure of the refrigerating machine. If we want to work with a minimum ambient temperature of 25 oC, for example in the case of conditioning a house, we have to load the machine at 13.42 atm so that the boiling temperature of ammonia is 35 oC. If the ambient temperature varies, it is detected by the probe (24). As the boiling temperature of ammonia is a function of the pressure of the

En el ejemplo anterior de realización podemos utilizar etanol o agua como disolvente en vez de metanol, aunque el etanol absorbe peor el amoniaco, por lo que la máquina tendría un peor COP que con metano!. En el caso de utilizar agua como disolvente es necesario el uso de un rectificador a la salida del generador (1) Y el aumento de la presión de trabajo lo que tan bien implica un peor COP de la máquina, In the previous example of embodiment we can use ethanol or water as solvent instead of methanol, although ethanol absorbs ammonia worse, so the machine would have a worse COP than with methane! In the case of using water as a solvent, it is necessary to use a rectifier at the generator outlet (1) and the increase in working pressure which implies a worse COP of the machine,
La Fig. 4 muestra en una forma esquemática otra forma de realización de un generador (1) de vapor de refrigerante que comprende un serpentín (2) recubierto de un material aislante del calor (3), que contiene un fluido caloportador (4) proveniente de una fuente de baja temperatura, el cual cede calor en el generador (1), retomando unos grados más frío y una espiral de malla (26) unida a las paredes del mismo y fabricada de un material resistente al refrigerante, por ejemplo aluminio, de un tamaño de la misma lo suficientemente pequeña como para que la disolución empobrecida empape la misma de modo que se aumenta considerablemente la superficie de evaporación y se desprende más vapor de refrigerante, Fig. 4 shows in a schematic form another embodiment of a refrigerant steam generator (1) comprising a coil (2) coated with a heat insulating material (3), containing a heat transfer fluid (4) from of a low temperature source, which yields heat in the generator (1), returning to a cooler degree and a spiral of mesh (26) attached to the walls of the generator and made of a material resistant to the coolant, for example aluminum, of a size thereof small enough for the impoverished solution to soak it so that the evaporation surface is considerably increased and more refrigerant vapor is released,
