Split air conditioning system with a single outdoor unit

A split air conditioning system for conditioning a plurality of zones within the same interior room of a building, the split air conditioning system comprising:

• a single outdoor unit comprising:
• a housing with a compressor;
• a condenser;
• and a condenser fan positioned within the housing wherein the condenser fan is associated with the condenser and configured to move air to cool the condenser and the compressor is a dual suction, variable speed compressor capable of and configured to deliver full cooling capacity to both a first evaporator and a second evaporator;
• 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 that delivers refrigerant to the first evaporator wherein the first evaporator is configured to operate at a first evaporator pressure and the second divergent flow path that delivers refrigerant to the second evaporator wherein the second evaporator is configured to operate at a second evaporator pressure and the first evaporator and second evaporator are in parallel with one another;
• at least two throttling devices wherein a first throttling device is positioned along the first divergent flow path to receive refrigerant fluid prior to the first evaporator and a second throttling device is positioned along the second divergent flow path to receive refrigerant fluid prior to the second evaporator;
• a first variable speed fan configured to move air across the first evaporator;
• a second variable speed fan configured to move air across the second evaporator;
• 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 plurality of refrigerant conduits making up the refrigerant flow path are free of any check valves.
