Development of an Optimised Control System for Multi-Temperature Refrigeration Systems

Popis výsledku v původním jazyce

The development of refrigerated transport technology has been forced in last year to improve temperature control techniques, provide greater capacity and flexibility without compromising either reliability or incresing capital cost. The main control variables were identified and a simplified fuzzy logic control algorithm was developed and applied to the modified system. System performance during cooling was recorded and compared with performance achieved when two different control algorithms were applied to the standard multi-zone refrigeration system with on/off type flow control valves. Using on/off-type control valves on the evaporator inlet line highlighted that set-point temperature control was sensitive to the frequency of activation, with temperature control improving as activation level increased. To verify the performance of this control system in the real life environment the same modified refrigeration system design was installed within a 12 m long trailer.
