Patent ID: 8677779

Claim:
An air conditioning system comprising: a compressor for compressing a refrigerant; an expansion valve coupled to the compressor for providing a metered flow of the compressed refrigerant; a primary evaporator for cooling a primary airflow and having a primary refrigerant path between a primary inlet and a primary outlet, wherein the primary inlet is coupled to the expansion valve for receiving the metered flow of refrigerant, wherein a vapor quality of the refrigerant has an initial value at the primary inlet and a resultant value at the primary outlet, and wherein the primary evaporator has a bypass inlet connected to the primary refrigerant path at a first location where the vapor quality of the refrigerant is less than 80% of the resultant value; and a secondary evaporator for cooling a secondary airflow and having a secondary inlet and a secondary outlet, wherein the secondary inlet receives a bypass portion of the metered flow of refrigerant split-off at a second location of the refrigerant path between the first location and the expansion valve, and wherein the secondary outlet is connected to the bypass inlet.
