Two evaporators with an expansion valve
Because the greater the pressure drop is large, resulting in the flow of liquid to the flow of less, have flow to the resistance of the smaller side.
Due to A pressure drop caused by B supply too much liquid back to the suction pipe, easy to return to the compressor, resulting in liquid hit.
If the evaporator is far from the title A, the other is the name B; expansion valve close to B, the temperature is wrapped in the total return air pipe, then
