Are there any problems associated with using oversized liquid recievers.

Basically i have pumpdown 15-16kg of charge, thus require about 18kg of pumpdown capacity. However have 28kg liquid reciever.

Is there problems with using oversized liquid reciever?? Will this result in gas being sucked out of liquid reciever back into the cycle thus reducing efficiency of system.

Also what problems are there associated if gas state refrigerant is drawn out of liquid reciever back into the cycle
