  • Air conditioning system with refrigerant charge management
    Patent number: 6735964
    Abstract: An air conditioning system includes an outdoor unit and multiple indoor units. Each of the indoor units has its own coil assembly and fan and is dedicated to heating a particular area within a building, for example. Not all of the indoor units operate at the same time. Managing the refrigerant charge level within the active part of the system includes controlling an amount of refrigerant flow through the inactive indoor units. When the active part of the system does not have an adequate charge, an increased return flow from the inactive indoor units to the outdoor unit serves to increase the charge. Under circumstances where there is an overcharge in the active part of the system, the inactive indoor units are effectively used as storage for excess refrigerant on a temporary basis.
