sistemas de controle
trocadores de calor
Abstract in Portuguese
O objetivo do trabalho é apresentar o desenvolvimento, simulação e resultados práticos de um Sistema de controle de temperatura, para Experimentos Biomédicos que utilizam soluções aquecidas com vazão variável. O Sistema utiliza um Trocador de Calor projetado para aquecer uma solução que entra no dispositivo a uma temperatura inferior ou igual à do ambiente e sai com o valor programado. A solução é aquecida a partir da água de um reservatório com temperatura controlada. O Controlador de temperatura é do tipo proporcional-integral-derivativo digital e utiliza um microcontrolador para implementação do algoritmo de controle, da aquisição do sinal dos sensores de temperatura, do comando de atuadores e da interface com o usuário

Abstract in English
The objective of the work is to present the development, simulation and practical results of a temperature control System for Biomedical Experiments that utilize heated solutions with variable outflow. The System uses a Heat Exchanger designed to heat the solution that enters into device with a lower or the same temperature as the environment and leaves with the programmed value. The Biomedical solution is heated using the Heat Exchanger and water of the reservoir where the temperature is controlled. The digital proportional-integral-derivative temperature Controller takes use of a microcontroller for implementation of the control algorithm, data acquisition of the temperature sensors, command of actuators and user interface
