The aim of this work was to propose the innovation of ventilator line in the laboratory of air-conditioning technique, to change power drive of ventilator and to propose a method of data logging. A substantial part of work was measurement of ventilator characteristic. It carried out first on ventilator line with an original direct-current motor powered by Ward-Leonard aggregate and after power drive change on ventilator line with an induction motor powered by frequency charger. The ventilator characteristic was measured at different revolutions that were operated by frequency of alternating current generated by the frequency charger. The measurements revealed a drawback of ventilator line consisting in too great pressure losses caused mainly by an orifice plate. They did not make it possible to realise complete measurement of ventilator characteristic. It was proposed to change the original orifice plate with diameter d = 54.77 mm for a new one with greater diameter (maximally d = 80.32). Such measure will decrease pressure losses several times. A method of automatic data logging for measurement on ventilator line was proposed. Necessary ranges of pressure sensors, temperature sensors, and air-humidity sensors used on ventilator line were estimated from supposed fluid-flow values and from the other conditions on the ventilator line. All sensors can be connected to the data logging system ADAM 5000 which is at disposal in the laboratory and which is connected to a computer. It would make it possible to process all measurement by computer. |
