An air conditioning system includes a supplemental storage container that allows for transferring refrigerant into or out of an air conditioning or refrigeration system based upon different operating conditions. In one example, a controller controls the operation of valves that selectively couple the storage container to the high pressure side or the low pressure side of the system. Depending on operating conditions, when it is desirable to increase an amount of refrigerant in the system, refrigerant is transferred from the storage container to the low pressure side of the air conditioning or refrigeration system. Under conditions where the amount of refrigerant in the system is above a desired amount, refrigerant can be transferred from the high side of air conditioning system to the storage container to bring the pressure within the system closer to the desired level.
