Adaptive control of air temperature through spraying of water

Resumo

The use of electric energy for acclimatization is increasing in the entire world, what encourages the interests for researches in alternative sources of energy, in development of new equipment. Nowadays, acclimatization by absorption, evaporative cooling and desiccant cooling researches are accomplish aiming the reduction in the use of electric energy. In this paper, air cooling of an environment is proposed by spraying of water. This system, named simulator, is made of two parts. The first aim is to production of air under determinate condition and the second has the objective of reduce the air temperature of a recipient through spraying of water. In the proposed adaptive temperature controller, the system parameters are estimated in real time such as the controller design and its parameters. As experimental results are shown: temperature response, the system parameters estimates, the controller parameters, control variable and estimation error.
