Design of high efficiency controller orient multi - evaporator refrigeration system
In terms of the high - efficient control problem of multi - vaporator refrigeration system, an accuracy control method based on model prediction control was proposed. The model distributed several single controllers on the multi evaporators so as to control the indexes such as refrigeration capacity and superheat of the whole refrigeration system. By modeling and analyzing the refrigeration cycles in the multi - vaporator compressors, the detailed relational expressions were given out so that the controllers based on model prediction were designed. The tests and simulations all show that the response actions of controllers are basically accordance with the refrigeration demands.
