description In words of the cooling technology experts, there is at least a 20-year gap between the nowadays vapor compression based technology for refrigeration, cooling and HVAC, and what we have defined as alternatives technologies. There is also a big amount of scientific effort to endow this vapor compression technology with more degrees of freedom to implement more accurate energy optimization algorithms. In this way, as a first step to get more robust control algorithms in heat interchangers of condenser and evaporators units, authors have developed some instrumentation systems to analyze the behavior of the air flowing through the rigid blades of this kind of devices. This previous effort has been before reported as a complete vibrational modal model for the concerned rigid grid, however; due to its 16 spatially degrees of freedom and its 16th dynamic order, its model re-solution on line while the heat interchanger unit is working is almost impossible with a normal computer. Therefore, to get an algorithm with less computational resource consumption and with the same accuracy than the complete modal model, authors have reported in this document, the implementation of a reduced dynamical order transfer function matrix model. Reduction that as well as it is described is based on the poles averaging and zeros selection, from the set experimental graphs of the frequency spectral magnitude from a set of impact tests (experimental modal testing) performed at LaNITeF-CIDESI. Numerical prediction of the transfer function matrix from the dynamic reduced order model have been validated with the experimental spectral. Based on the hypothesis, that due to the incident angle, the resonance spectral vibration is excited by the laminar air flow, while the air flow turbulence does not excite the resonance vibrational spectral, the turbulence ration from the incident air flow has been analyzed from a wind tunnel test. As the main conclusion, authors have developed and validated a new instrumentation system to analyze the turbulence ratio of the air flow incident in a rigid grid, which can be part of a condenser or evaporator unit from a conventional cooling system, by implementing the concerned transfer functions matrix model with reduced dynamic order.

Modelo modal vibracional Flujo de aire laminar y turbulento Reduzca la matriz de funciones de transferencia de orden.

En palabras de los expertos en tecnología de enfriamiento, existe al menos una brecha de 20 años entre la tecnología actual basada en la compresión de vapor para refrigeración, enfriamiento y HVAC, y lo que hemos definido como tecnologías alternativas. También hay una gran cantidad de esfuerzo científico para dotar a esta tecnología de compresión de vapor con más grados de libertad para implementar algoritmos de optimización de energía más precisos. De esta manera, como primer paso para obtener algoritmos de control más robustos en intercambiadores de calor de unidades de condensadores y evaporadores, los autores han desarrollado algunos sistemas de instrumentación para analizar el comportamiento del aire que fluye a través de las cuchillas rígidas de este tipo de dispositivos. Sin embargo, este esfuerzo anterior se informó anteriormente como un modelo modal vibracional completo para la grilla rígida en cuestión; Debido a sus 16 grados de libertad espacial y su 16 ° orden dinámico, su redisolución de modelo en línea mientras la unidad de intercambiador de calor está funcionando es casi imposible con una computadora normal. Por lo tanto, para obtener un algoritmo con menos consumo de recursos computacionales y con la misma precisión que el modelo modal completo, los autores han informado en este documento, la implementación de un modelo de matriz de función de transferencia de orden dinámico reducido. Reducción que, como se describe, se basa en el promedio de los polos y la selección de ceros, a partir de los gráficos experimentales establecidos de la magnitud espectral de frecuencia de un conjunto de pruebas de impacto (prueba modal experimental) realizadas en LaNITeF-CIDESI. La predicción numérica de la matriz de la función de transferencia del modelo dinámico de orden reducido se ha validado con el espectro experimental. Según la hipótesis, que debido al ángulo incidente, la vibración espectral de resonancia es excitada por el flujo de aire laminar, mientras que la turbulencia del flujo de aire no excita la espectral vibracional de resonancia, la relación de turbulencia del flujo de aire incidente se ha analizado desde un prueba de túnel de viento. Como conclusión principal, los autores han desarrollado y validado un nuevo sistema de instrumentación para analizar la relación de turbulencia del flujo de aire incidente en una red rígida, que puede ser parte de una unidad de condensador o evaporador de un sistema de enfriamiento convencional, mediante la implementación de la transferencia correspondiente. modelo matricial de funciones con orden dinámico reducido.
