Abstract: In order to realize the high-precision temperature control of domestic refrigerator chilling chamber and freezing chamber, save power and energy, the functional topology relation diagram of domestic refrigerator is established, and the simulation models of domestic refrigerator chilling chamber, freezing chamber, PID controller, condenser, heat exchanger and so on are designed based on AMESim. The PID controller is debugged by simulation test, and the more appropriate control parameters are obtained. By setting the temperature of environment and the control temperature of chilling chamber and freezing chamber, the tracking temperature situation of the refrigerator is obtained. The results show that the controller has reached a higher control accuracy and level, which provides a reference for the PI control and simulation of the gas-liquid two-phase flow temperature of the domestic inverter refrigerator.

Keywords: domestic refrigerator; two-phase flow; temperature control; PID controller; computer simulation
