Abstract
Prispevek predstavlja krmiljenje hladilnih sistemov. Namen raziskave je pomoč pri projektiranju hladilnih sistemov oziroma pri določevanju optimalnih parametrov, ki vplivajo na delovanje hladilnih sistemov. Za obravnavo je bila potrebna analiza trenutnega stanja ponudnikov oziroma izdelovalcev opreme za krmiljenje hladilnih sistemov. Opremo lahko delimo na dva dela. Obstaja oprema za krmiljenje preprostih hladilnih sistemov, ki se največkrat sestoji iz elektronskih termostatov za krmiljenje elementov v hladilnih komorah ali miniaturnih mikroprocesorskih naprav za krmiljenje manjsih kompresorskih agregatov. Uporaba nastete opreme je postala ze sirokoporabna, tako da sta njena prednost nizka cena in preprosta uporaba. Slabe lastnosti omenjene opreme pa so predvsem neuporabnost za zahtevnejse hladilne sisteme ter nezmožnost optimizacije hladilnih sistemov v smislu povečevanja hladilnega stevila in varčevanja z električno energijo. Poudarek prispevka je zaradi naštetih dejstev predvsem v krmiljenju zahtevnejših hladilnih sistemov z uporabo prostoprogramljivih mikroprocesorjev in sistema SCADA.

Title:Control in refrigeration systems
Abstract:
This paper describes the control of refrigeration systems. The goal of the research is to support the design of refrigeration systems and to define the optimum parameters that influence refrigerating systems. A second aim of the investigation was an analysis of currently available control equipment for refrigeration systems and the producers. The equipment can be divided into two segments: equipment for the control of simple refrigeration systems, which consists of electronic thermostats for controlling the elements of the refrigeration rooms; and miniature microprocessor-based equipment used for controlling the smallest compressor aggregates. The advantages of this equipment are its his wide consumption, low cost and simple usage. Its drawbacks are inappropriateness for complex refrigeration systems in the senseof increasing the coefficient of performance (COP) and the consumption ofelectrical energy. The main emphasis of the paper is on the control of complex refrigeration systems based on programmable microprocessors and SCADA (supervisory control and data acquisition) systems.

Keywords:refrigeration systems, control systems, control equipment, SCADA systems
