文摘

Modelling, optimization and control of vapour compression refrigeration systems. A control-oriented reduced model based on the moving boundary approach is presented. Steady-state global optimization of a one-stage, one-load-demand cycle. The control problem is underactuated when seeking the optimum. Controllability study reveals some issues when optimally controlling the cycle.
