20.500.12556/RUL-139642 Primerjava med linearno in nelinearno karakteristiko regulacijskega ventila Comparison between linear and non-linear characteristics of a control valve Za regulacijo temperature v sobi se uporablja hladilno/grelna enota, ki se regulira preko regulacijskega ventila s pogonom. Za dobro ugodje in optimalno kontrolo potrebujemo linearen odziv sistema. V diplomskem delu je predstavljena zasnova in sestava merilne proge, na kateri smo izvajali meritve o vplivu pretočne karakteristike regulacijskega ventila na odziv sistema. Meritve smo izvedeli s prilagojeno in neprilagojeno karakteristiko regulacijskega ventila s pogonom glede na enoto in opazovali vpliv skupne karakteristike na regulacijsko sposobnost sistema. The room temperature is controlled by a cooling/heating unit, which is regulated by control valve with actuator. For good comfort and optimal control, we need a linear response from the system. The thesis presents the design and construction of the measurement line on which We performed measurements on the influence of the flow characteristic of the control valve and actuator on the system response. We made measurements with the linear valve and actuator characteristic and with characteristic of valve and actuator fitted to characteristic of cooling/heating unit and observed the effect of the overall characteristic on the control capability of the system. regulacijski ventil karakteristika regulacijskega ventila tlačno neodvisen regulacijski ventil odziv sistema alfa krivulja področja hladilne moči prilagojena karakteristika ventila control valve control valve characteristic pressure independent control valve system response cooling load alpha value curve fitted control valve characteristic true false false [J.
