DESCRIPCIONDESCRIPTION
Procedimiento para la regulacion de un equipo de calentamiento y equipo de calentamientoProcedure for the regulation of heating equipment and heating equipment
La invencion se refiere a un procedimiento para la regulacion de un equipo de calentamiento segun el preambulo de la reivindicacion 1. Ademas, la invencion se refiere a un equipo de calentamiento, de acuerdo con la reivindicacion 6, para llevar a cabo el procedimiento.The invention relates to a procedure for the regulation of a heating equipment according to the preamble of claim 1. In addition, the invention relates to a heating equipment, according to claim 6, for carrying out the process.
Tales equipos de calentamiento sirven para calentar un medio de calentamiento, utilizandose por regla general agua caliente. El equipo de calentamiento presenta a este respecto una camara de combustion, en la que se quema un combustible, como por ejemplo un gas. A este respecto se suministra aire de combustion a traves de un soplador. El calor que se libera es transferido en un intercambiador de calor al medio de calentamiento.Such heating equipment serves to heat a heating medium, generally using hot water. The heating equipment in this regard has a combustion chamber, in which a fuel is burned, such as a gas. In this respect combustion air is supplied through a blower. The heat that is released is transferred in a heat exchanger to the heating medium.
Para una combustion mas limpia resulta esencial una correcta relacion del volumen de aire de combustion suministrado y la cantidad de combustible suministrada. Si se suministra demasiado poco aire, el combustible puede no quemarse por completo. Debido a ello se producen altas emisiones de sustancias contaminantes, en particular de monoxido de carbono e hidrocarburo. Si se suministra demasiado aire, se enfrla la combustion, lo que lleva igualmente a mayores emisiones de sustancias contaminantes.For a cleaner combustion, a correct ratio of the volume of combustion air supplied and the amount of fuel supplied is essential. If too little air is supplied, the fuel may not burn completely. As a result, high emissions of pollutants occur, particularly carbon monoxide and hydrocarbon. If too much air is supplied, the combustion is cooled, which also leads to higher emissions of pollutants.
Habitualmente se realiza un control de la cantidad de aire de combustion suministrado mediante el correspondiente control del soplador. El soplador presenta por regla general una rueda de soplador, cuya velocidad de giro influye en el flujo volumetrico del aire de combustion, es decir en el volumen por unidad de tiempo. A este respecto puede monitorizarse el flujo volumetrico.Usually a control of the amount of combustion air supplied is performed by means of the corresponding blower control. The blower generally has a blower wheel, whose speed of rotation influences the volumetric flow of combustion air, that is, the volume per unit of time. In this respect the volumetric flow can be monitored.
Se sabe como determinar el flujo volumetrico mediante medicion de la presion diferencial. Para ello se propone por ejemplo en el documento DE l0 159 033 A1 detectar una presion en dos puntos de medicion diferentes. Puesto que entre ambos puntos de medicion, debido a una diferencia de velocidad, una presion estatica del aire de combustion se convierte parcialmente en una presion dinamica, puede medirse entre los puntos de medicion una presion diferencial. A partir de la misma puede determinarse de manera conocida el flujo volumetrico. Ademas se mide la velocidad de giro de una rueda de soplador y teniendo en cuenta el diseno del aparato se determina as! el flujo volumetrico. Se obtiene con ello un sistema de control redundante.It is known how to determine the volumetric flow by measuring differential pressure. For this, it is proposed, for example, in DE 10 159 033 A1 to detect a pressure at two different measuring points. Since between the two measuring points, due to a difference in velocity, a static pressure of the combustion air is partially converted into a dynamic pressure, a differential pressure can be measured between the measuring points. From it, the volumetric flow can be determined in a known manner. In addition, the speed of rotation of a blower wheel is measured and taking into account the design of the device is determined as follows! Volumetric flow This results in a redundant control system.
Este procedimiento requiere una conduccion de aire especial y varios puntos de medicion. Es por tanto relativamente complejo y por tanto muy costoso. A este respecto pueden falsearse los resultados de medicion, por ejemplo debido a suciedad o debido a variaciones de parametros. Ademas existe el problema de la aparicion de deriva y otros problemas de envejecimiento.This procedure requires a special air duct and several measuring points. It is therefore relatively complex and therefore very expensive. In this respect the measurement results may be falsified, for example due to dirt or due to variations in parameters. There is also the problem of the appearance of drift and other aging problems.
En el documento DE 19 945 562 A1 se describe un procedimiento para monitorizar y/o regular un aparato de calefaccion de vehlculo, en el que se regula una velocidad de giro de un soplador para el control de un flujo volumetrico de un aire de combustion. A este respecto se monitoriza una combustion en al camara de combustion mediante un sensor de presion o de presion acustica.Document DE 19 945 562 A1 describes a procedure for monitoring and / or regulating a vehicle heating apparatus, in which a rotational speed of a blower is regulated for the control of a volumetric flow of a combustion air. In this regard, combustion is monitored in the combustion chamber by means of a pressure or acoustic pressure sensor.
En el documento DE 10 2005 011 021 A1 es un procedimiento para adaptar la potencia de calefaccion del aparato de un de calentamiento apoyado por un soplador a las perdidas de presion individuales de un sistema de conduccion de aire nuevo-gas de escape, detectandose una velocidad de giro del soplador y una potencia del soplador. Si la relacion de la velocidad de giro del soplador respecto a la potencia del soplador medida no se situa en un intervalo predefinible, se emite un aviso de error.In document DE 10 2005 011 021 A1 is a procedure for adapting the heating power of the apparatus of a heating system supported by a blower to the individual pressure losses of a new air-exhaust gas conduction system, detecting a speed Blower rotation and blower power. If the ratio of the speed of rotation of the blower to the measured blower power is not within a predictable range, an error message is issued.
Ademas se sabe como averiguar un flujo masico a traves de sensores de alambre de calefaccion. Sin embargo estos son relativamente caros y sensibles. A este respecto aparecen con frecuencia derivas.It is also known how to find out a mass flow through heating wire sensors. However, these are relatively expensive and sensitive. In this respect drifts frequently appear.
La invencion se basa en el objetivo de paliar las desventajas del estado de la tecnica y posibilitar en particular una regulacion del equipo de calentamiento con una complejidad reducida.The invention is based on the objective of alleviating the disadvantages of the state of the art and in particular enabling regulation of the heating equipment with reduced complexity.
De acuerdo con la invencion esto se consigue con las caracterlsticas de la reivindicacion 1. Perfeccionamientos ventajosos pueden derivarse de las reivindicaciones dependientes.According to the invention this is achieved with the characteristics of claim 1. Advantageous improvements can be derived from the dependent claims.
De acuerdo con la reivindicacion 1 se averiguan una presion estatica y/o una absorcion de potencia del soplador, determinandose un coeficiente de flujo volumetrico con ayuda de la velocidad de giro en asociacion con la presion estatica y/o la absorcion de potencia. Una deteccion de la velocidad de giro esta prevista por regla general en cualquier caso en sopladores controlables de manera variable. Ademas tambien tiene que preverse solo un sensor para la deteccion de la presion estatica y/o de la absorcion de potencia del soplador. Esto puede implementarse con muy poca complejidad. A este respecto, tales sensores pueden obtenerse como artlculos de serie muy economicos.According to claim 1, a static pressure and / or a blower power absorption are determined, a volumetric flow coefficient being determined with the aid of the rotational speed in association with the static pressure and / or the power absorption. A detection of the speed of rotation is provided as a rule in any case in controllable blowers of variable way. In addition, only one sensor must be provided for the detection of static pressure and / or blower power absorption. This can be implemented with very little complexity. In this regard, such sensors can be obtained as very economical series articles.

Preferiblemente se averiguan valores de referenda para un coeficiente de presion y/o un coeficiente de potencia en funcion de un coeficiente de flujo volumetrico en un soplador de referencia, teniendose en cuenta los valores de referencia en la determinacion del flujo volumetrico. El coeficiente de presion H es dependiente de la aceleracion de la gravedad g, de la velocidad de giro N, del diametro D de la rueda de soplador as! como de la presion estatica h y se calcula segun la siguiente formula:Preferably reference values for a pressure coefficient and / or a power coefficient are determined as a function of a volumetric flow coefficient in a reference blower, taking into account the reference values in the determination of the volumetric flow. The pressure coefficient H is dependent on the acceleration of gravity g, the speed of rotation N, the diameter D of the blower wheel as! as of the static pressure h and is calculated according to the following formula:
Dado que la aceleracion de la gravedad g es una magnitud constante y el diametro de la rueda de soplador es un valor invariable conocido, tras la medicion de la presion estatica y de la velocidad de giro es posible determinar el coeficiente de presion.Since the acceleration of gravity g is a constant magnitude and the diameter of the blower wheel is a known invariable value, after measuring the static pressure and the speed of rotation it is possible to determine the pressure coefficient.
El coeficiente de potencia P es dependiente de la absorcion de potencia W, de la densidad del aire de combustion p, de la velocidad de giro N, del diametro D y se calcula segun la siguiente formula:The power coefficient P is dependent on the power absorption W, the density of the combustion air p, the rotational speed N, the diameter D and is calculated according to the following formula:
La densidad del aire de combustion puede considerarse casi constante. No obstante, para mayor precision tambien puede detectarse adicionalmente la densidad. El diametro de la rueda de soplador es constante. Mediante la deteccion de la velocidad de giro y la absorcion de potencia es posible calcular por tanto el coeficiente de potencia de manera sencilla.The density of combustion air can be considered almost constant. However, for greater accuracy the density can also be detected. The diameter of the blower wheel is constant. By means of the detection of the speed of rotation and the absorption of power it is possible to calculate therefore the coefficient of power of simple way.
El coeficiente de flujo volumetrico F, que es una funcion cuadratica del coeficiente de presion y del coeficiente de potencia, es dependiente del flujo volumetrico V, de la velocidad de giro N as! como del diametro D y se calcula segun la siguiente formula:The volumetric flow coefficient F, which is a quadratic function of the pressure coefficient and the power coefficient, is dependent on the volumetric flow V, the rotational speed N as! as of diameter D and is calculated according to the following formula:
Respecto al coeficiente de presion o coeficiente de potencia calculado en cada caso sobre la base de la velocidad de giro medida y de la absorcion de potencia medida o de la presion estatica medida es posible determinar con ayuda de valores de referencia, obtenidos en un soplador geometricamente similar y depositados por ejemplo en forma de curvas caracterlsticas, el coeficiente de flujo volumetrico. A partir del mismo es posible determinar entonces con relativa facilidad el flujo volumetrico mediante la formula (3) anterior. El flujo volumetrico puede averiguarse por tanto con una complejidad relativamente reducida. Para aumentar la seguridad de funcionamiento puede averiguarse el flujo volumetrico dado el caso tambien en paralelo por dos vlas, es decir una vez a traves de la medicion de la absorcion de potencia y por otro lado a traves de la deteccion de la presion estatica. Para poder determinar el flujo volumetrico con suficiente precision, el numero de Reynolds deberla ser suficientemente alto y las influencias de la viscosidad deberlan ser reducidas. Pero esto se da por regla general.Regarding the pressure coefficient or power coefficient calculated in each case on the basis of the measured rotational speed and the measured power absorption or the measured static pressure, it is possible to determine with reference values obtained in a geometrically blower similar and deposited for example in the form of characteristic curves, the volumetric flow coefficient. From it it is then possible to determine with relative ease the volumetric flow by means of the formula (3) above. The volumetric flow can therefore be ascertained with a relatively reduced complexity. In order to increase the operational safety, the volumetric flow can be ascertained, if necessary, in parallel by two routes, that is, once through the measurement of the power absorption and, on the other hand, through the detection of the static pressure. In order to determine the volumetric flow with sufficient precision, the Reynolds number should be sufficiently high and the viscosity influences should be reduced. But this is a general rule.
Preferiblemente se averigua la absorcion de potencia del soplador a partir de la potencia electrica absorbida por un motor de soplador electrico, teniendose en cuenta un rendimiento. Esta asociado a una menor complejidad detectar la absorcion de potencia electrica que determinar una potencia mecanica de la rueda de soplador. A este respecto, la potencia mecanica es dependiente de la potencia electrica y del rendimiento, que es dependiente de una carga y de una velocidad de motor. Este rendimiento puede averiguarse por ejemplo experimentalmente y despues depositarse en un control. La conexion entre absorcion de potencia electrica y potencia mecanica se establece como sigue, designando r|e el rendimiento, que es por ejemplo dependiente de la carga y de una velocidad de motor:Preferably, the blower power absorption is determined from the electric power absorbed by an electric blower motor, taking into account a performance. It is associated with less complexity to detect the absorption of electric power than to determine a mechanical power of the blower wheel. In this regard, mechanical power is dependent on electrical power and performance, which is dependent on a load and motor speed. This performance can be determined, for example, experimentally and then deposited in a control. The connection between electrical power absorption and mechanical power is established as follows, designating r | e performance, which is for example dependent on the load and motor speed:

Preferiblemente se averigua la presion estatica por detras del soplador en el sentido aguas abajo. Con el soplador desconectado puede averiguarse entonces la presion de aire actual mientras que durante el funcionamiento puede determinarse la presion estatica del aire de combustion con relativa precision.Preferably, the static pressure behind the blower in the downstream direction is determined. With the blower switched off, the current air pressure can then be ascertained, while during operation the static pressure of the combustion air can be determined with relative precision.
El objetivo se alcanza tambien mediante el equipo de calentamiento para llevar a cabo el procedimiento con las caracterlsticas de la reivindicacion 6.The objective is also achieved by means of the heating equipment to carry out the process with the characteristics of claim 6.
Este equipo de calentamiento sirve para calentar un medio de calentamiento, en particular agua caliente, y presenta una camara de combustion a la que pueden suministrarse a traves de un soplador aire de combustion y a traves de una conduccion de alimentacion combustible. A este respecto, el equipo de calentamiento presenta un sensor de velocidad de giro y un sensor de presion y/o un sensor de potencia. Mediante la determinacion del flujo volumetrico del aire de combustion es posible regular entonces adecuadamente la combustion. En particular puede adaptarse el volumen suministrado de aire de combustion en funcion de la cantidad de combustible suministrado. As! se garantiza una combustion optima.This heating equipment serves to heat a heating medium, in particular hot water, and has a combustion chamber which can be supplied through a combustion air blower and through a fuel supply line. In this regard, the heating equipment has a rotation speed sensor and a pressure sensor and / or a power sensor. By determining the volumetric flow of combustion air it is then possible to properly regulate combustion. In particular, the volume of combustion air supplied can be adapted according to the amount of fuel supplied. Ace! Optimal combustion is guaranteed.
La invention se describe a continuation mas detalladamente con ayuda de diversos ejemplos de realization en asociacion con los dibujos. En los mismos muestran en vista esquematica:The invention is described below in more detail with the help of various realization examples in association with the drawings. They show in schematic view:

En la figura 1 esta representado esquematicamente un equipo de calentamiento, que presenta un soplador 1, un quemador, un intercambiador de calor 3, un canal de evacuation 4 y un tubo de evacuation 5. A traves del sopladorIn Fig. 1, a heating device is shown schematically, showing a blower 1, a burner, a heat exchanger 3, an evacuation channel 4 and an evacuation tube 5. Through the blower

Se transporta hasta el quemador1 combustion air is transported to a combustion chamber of the heating equipment. The burner 2 and the heat exchanger 3 are also arranged in the combustion chamber. It is transported to the burner.
2 combustible, como por ejemplo un gas. Sin embargo esto no esta representado. Para abastecer el soplador 1 con energla este presenta una interfaz de abastecimiento 1.2.2 fuel, such as a gas. However this is not represented. To supply blower 1 with energy, it has a supply interface 1.2.
En el intercambiador de calor 3 se transfiere el calor que se libera en el quemador a un medio de calentamiento, como por ejemplo agua caliente.In the heat exchanger 3, the heat that is released in the burner is transferred to a heating medium, such as hot water.
Para una combustion mas limpia y con pocas emisiones se requiere ajustar el volumen suministrado de aire de combustion a la cantidad suministrada de combustible. Un flujo volumetrico se ve afectado a este respecto fundamentalmente por una velocidad de giro del soplador 1. La velocidad de giro de una rueda de soplador se detecta por tanto por medio de un sensor de velocidad de giro 1.1, que esta configurado por ejemplo como sensor de Hall. A traves de un sensor de presion 1.3 se averigua una presion estatica del aire de combustion entre soplador 1 y quemador 2.For a cleaner and low emission combustion, it is required to adjust the volume of combustion air supplied to the amount of fuel supplied. A volumetric flow is affected in this respect primarily by a speed of rotation of the blower 1. The speed of rotation of a blower wheel is therefore detected by means of a rotation speed sensor 1.1, which is configured for example as a sensor Hall A static combustion air pressure between blower 1 and burner 2 is determined through a pressure sensor 1.3.
El sensor de presion 1.3 y el sensor de velocidad de giro 1.1 estan conectados a un control 6 que, con ayuda de los valores medidos para una velocidad de giro de la rueda de soplador y de la presion estatica, calcula un flujo volumetrico. Para ello, el control 6 presenta una memoria, en la que estan depositados valores de referencia para un coeficiente de presion, un coeficiente de potencia y un coeficiente de flujo volumetrico en forma de curvas caracterlsticas. Estos valores de referencia se determinaron en un soplador de referencia y son trasladables a sopladores con dimensiones geometricas similares. La determinacion del flujo volumetrico puede producirse por tanto con relativa facilidad mediante la detection de la velocidad de giro y de la presion estatica.The pressure sensor 1.3 and the rotation speed sensor 1.1 are connected to a control 6 which, using the measured values for a rotation speed of the blower wheel and the static pressure, calculates a volumetric flow. For this, the control 6 has a memory, in which reference values are deposited for a pressure coefficient, a power coefficient and a volumetric flow coefficient in the form of characteristic curves. These reference values were determined in a reference blower and are transferable to blowers with similar geometric dimensions. The determination of the volumetric flow can therefore occur with relative ease by detecting the speed of rotation and the static pressure.
En la figura 2 esta representada una forma de realizacion ligeramente diferente con respecto a la figura 1. Elementos iguales y mutuamente correspondientes estan dotados en la misma de los mismos numeros de referencia.A slightly different embodiment is shown in Figure 2 with respect to Figure 1. Equal and mutually corresponding elements are provided therein with the same reference numbers.
Ademas de la deteccion de la velocidad de giro de la rueda de soplador a traves del medidor de velocidad de giro 1.1 se mide en esta forma de realizacion una absorcion de potencia a traves de un sensor de potencia y se pone a disposition del control 6. A este respecto se realiza una medicion de la potencia electrica, que se suministra a un motor del soplador 1. Con ayuda de esta potencia y de la velocidad de giro calcula entonces el control el flujo volumetrico conducido por el soplador 1 hasta el quemador 2 o a la camara de combustion.In addition to the detection of the speed of rotation of the blower wheel through the rotation speed meter 1.1, a power absorption through a power sensor is measured in this embodiment and control 6 is made available. In this regard, a measurement of the electric power is performed, which is supplied to a blower motor 1. With this power and the rotation speed, the control calculates the volumetric flow conducted by the blower 1 to the burner 2 or the combustion chamber.
La figura 3 es un diagrama en el que en una primera curva caracterlstica esta representado el coeficiente de presion H y en una segunda curva caracterlstica esta representado el coeficiente de potencia P en cada caso a traves de un coeficiente de flujo volumetrico F. A este respecto se trata de curvas caracterlsticas que se averiguaron a partir de valores de referencia.Figure 3 is a diagram in which in a first characteristic curve the pressure coefficient H is represented and in a second characteristic curve the power coefficient P is represented in each case through a volumetric flow coefficient F. In this respect These are characteristic curves that were determined from reference values.
Mediante la deteccion de la velocidad de giro y de la presion estatica es posible determinar el coeficiente de presion con la formula (1) indicada anteriormente. A partir de la curva caracteristica de acuerdo con la figura 3 puede sacarse entonces el coeficiente de flujo volumetrico y calcularse a partir del mismo el flujo volumetrico con ayuda de la formula (3) anterior.By detecting the speed of rotation and the static pressure it is possible to determine the pressure coefficient with the formula (1) indicated above. From the characteristic curve according to figure 3, the volumetric flow coefficient can then be extracted and the volumetric flow calculated from it using the above formula (3).
5 De manera correspondiente, con la formula (2) anterior puede averiguarse el coeficiente de potencia mediante la deteccion de la velocidad de giro y la potencia absorbida y determinarse con ayuda de la curva caracteristica en la figura 3 el coeficiente de flujo volumetrico correspondiente. A partir del mismo puede calcularse el flujo volumetrico con la formula (3) anterior.5 Correspondingly, with the formula (2) above, the power coefficient can be determined by detecting the speed of rotation and the absorbed power and determining the corresponding volumetric flow coefficient using the characteristic curve in Figure 3. From it, the volumetric flow can be calculated with the formula (3) above.
El procedimiento de acuerdo con la invention y el equipo de calentamiento de acuerdo con la invention permiten por 10 tanto averiguar el flujo volumetrico con una complejidad reducida. A este respecto solo se requieren dos sensores, concretamente un sensor de velocidad de giro y un sensor de presion o un sensor de velocidad de giro y un sensor de potencia. Por lo demas, el calculo se realiza con ayuda de valores y funciones memorizados. Asi, la determination del flujo volumetrico solo esta sujeta a un indice de error reducido. Puede garantizarse asi una combustion mas limpia y con pocas emisiones.The process according to the invention and the heating equipment according to the invention therefore allow to determine the volumetric flow with reduced complexity. Only two sensors are required in this regard, namely a speed sensor and a pressure sensor or a speed sensor and a power sensor. For the rest, the calculation is made with the help of memorized values and functions. Thus, the determination of the volumetric flow is only subject to a reduced error rate. This way, a cleaner combustion with few emissions can be guaranteed.
