An air conditioning system has one expansion valve supplying refrigerant to two evaporators. A vapor quality of a refrigerant has an initial value at a primary inlet of a primary evaporator, and has a resultant value at the primary outlet. The primary evaporator has a bypass inlet at a first location where the vapor quality of the refrigerant is less than about 80% of the resultant value. A secondary evaporator has a secondary inlet receiving a bypass portion of the metered flow of refrigerant split-off at a second location of the primary evaporator between the first location and the expansion valve. The secondary outlet is connected to the bypass inlet. Thus, cooling can be achieved for two different zones using only one expansion valve. |
