Abstract
An air conditioning system including a refrigeration system with two evaporators having dissimilar heat transfer surfaces which combine to produce a cooling effect. The first evaporator includes a first heat transfer surface with a high efficiency or heat rejection (heat absorption) rate which is optimally configured for use in an environment having a low humidity level. The second evaporator includes a second heat transfer surface with a lower efficiency or lower heat rejection (heat absorption) rate as compared to the first heat transfer surface but which performs better in environments having higher humidity levels. Refrigerant to the first and second evaporators is controlled for a given ambient air humidity level to attain maximum efficiency. A cooling method for a refrigeration system is also provided.
