Claim:
1. A split air conditioning system for conditioning a plurality of zones within a single living area of a building, the split air conditioning system comprising: a single outdoor unit comprising: a compressor; a condenser; and a condenser fan associated with the condenser that moves air to cool the condenser; a refrigerant flow pathway comprised of a plurality of refrigerant conduits having a common refrigerant flow path, portion and at least two divergent flow path portions, a first divergent flow path portion that delivers refrigerant to a first evaporator configured to operate at a first evaporator pressure and a second divergent flow path portion that delivers refrigerant to a second evaporator such that the first evaporator and second evaporator are in parallel with one another; at least one throttling device wherein a throttling device is positioned along the common refrigerant flow path portion when a single throttling device is used and a first throttling device is positioned along the first divergent flow path portion and a second throttling device is positioned along the second divergent flow path portion when two or more throttling devices are employed; a portioning device configured to selectively and proportionately regulate the flow of a refrigerant fluid to the first evaporator and the second evaporator, respectively; wherein the compressor is configured to be capable of simultaneously driving both the first evaporator and the second evaporator at their full cooling capacity and wherein the first evaporator is positioned within a housing of a first indoor air unit positioned within the single living area of the building and the second evaporator is positioned within a housing of a second indoor air unit and both the first and second indoor air units each further comprise a fan configured to drive air across the first evaporator of the first indoor air unit and across the second evaporator of the second indoor air unit; and wherein the first evaporator is a disjointed evaporator and the second evaporator is a disjointed evaporator such that each indoor air unit is configured to control the ratio of the latent to sensible cooling capacity of the evaporator, fan speed, and proportional flow of refrigerant to different evaporator sections of the disjointed evaporators.
