Based on the component models of refrigerator-freezer (RF) described in Part 1, algorithm for system simulation of a natural convection bypass two-circuit cycle refrigerator-freezer is further put forward, and the system simulation is first done in this part. Then the system model is validated by experiments carried out on a Haier BCD-188F RF charged with R600a. Tests show that simulated results are in good agreement with the experimental data, which leads to the conclusion that the simulation model can be used to analyze dynamic characteristics of bypass two-circuit cycle refrigerator-freezers and optimize the units. After the validation, improvement of BCD-188F is done with the help of simulation program, and an improved prototype of BCD-188F is made. Tests on the prototype show that it is qualified and reaches the expected goal.
