A comparative analysis of temperature control algorithms for spray booths

Authors present a development of the temperature control system in the spray booth equipped with the two - state burner. The paper presents results of temperature control for different conditions of the external air temperature. A typical two-state algorithm isn’t enough effective to minimise temperature fluctuation amplitudes inside a spray booth. Minimisation of the number of burner ignitions with acceptable fluctuation amplitudes of the temperature is possible by means of : modification of the measurement loop, modifications of the two-state algorithm. Minimisation of number of burner ignitions will increase durability of the burner and decrease consumption fuel used to start the burner. In the final part of the article selected results of real time experiments were presented and shortly analysed.
