Abstract

The technical theory of VRV central mini air-conditioners is analyzed in this paper, aim at the limitation of fuzzy control and PID control for superheat control, the fuzzy control with variable region method is used to control evaporator-superheat, the problem of refrigerating matching and the superheat control definition for more than one evaporator in VRV central mini air-conditioners is solved. Simulation results show that fuzzy control with variable region for VRV central mini air-conditioners is superior to fuzzy control in the superheat control definition.
