CONSTRUCTION AND ANALYSIS OF A CONTROL VALVE IN AN OPEN LOOP COOLING SYSTEM

CONSTRUCCION Y ANALISIS DE UNA VALVULA DE CONTROL EN LAZO ABIERTO EN UN SISTEMA DE REFRIGERACION
MSc(c). Emil Hernández Arroyo.

Abstract: This deals with the project of design, construction and implementation of a control valve in open loop for the cooling system of the pilot plant, located in the laboratory of the Universidad Pontificia Bolivariana Bucaramanga branch. The design parameters are determined by the properties of the system named above, and its construction is made simple and economical. Similarly, adjusting for control, a LOGO! RC 12/24. The result is the graphic output flow vs. temperature in the heat exchangers. It also proposes the optimal working temperature for the cooling system.

Keywords : Flow, valve, cooling system, open loop control.

Resumen: Este documento se basa en el desarrollo del proyecto para el diseño, construcción e implementación de una válvula de control en lazo abierto, para el sistema de enfriamiento de la planta piloto, ubicada en el laboratorio de la Universidad Pontificia Bolivariana seccional Bucaramanga. Los parámetros de diseño se determinan según las propiedades de funcionamiento del sistema anteriormente nombrado; y su construcción se hace de forma sencilla y económica. De igual forma, se adapta para su control, un LOGO! 12/24 RC. Como resultado, se obtiene la grafica caudal vs temperatura de salida en los intercambiadores de calor. También, se propone la temperatura óptima de trabajo, para el sistema de enfriamiento.

Palabras clave: Flujo, válvula, sistema de refrigeración, control en lazo abierto.
