Using this model simulates and analyses the steady state characters and coupling relationship between the two evaporators. Finds that the coupling relationship can be attributed to the flow distribution ratio between the two expansion valves and the effect of the pressure at the common outlet and that there is a maximum value for refrigerating capacity and COP respectively when increasing the authority expansion...
