The present invention provides a vehicle air-conditioning system in which an air for air-conditioning is cooled at a first evaporator, is heated at a condenser, and is supplied to a vehicle interior in heating operation. The object of the present invention is to suppress a dew condensation at the first evaporator to prevent a freeze of the dew condensation water even if the temperature of the air for air-conditioning introduced from the outside of the vehicle is low. The above object is achieved by disposing a second evaporator between an automated expansion valve to decompress the refrigerant exhausted from a compressor and the first evaporator so as to reduce the absorbed heat at the first evaporator.

In an air conditioning system a method for controlling enthalpy in the environment of a structure is disclosed. The blower speed is controlled in such a manner as to maintain the prescribed dew point temperature of the air passing over the evaporator coils. When the air to be cooled contains high relative humidity, a greater quantity of latent heat is rejected into the evaporator, resulting in less sensible heat being rejected. This results in higher sensible temperature of air passing over the evaporator coils and thus the blower speed is reduced in and effort to maintain dew point. Maintaining the prescribed dew point ensures that the air in the space is continuously maintained at the optimum humidity levels without the use of humidity sensors. Enthalpy is determined by observing relative blower speed and the refrigeration compressor is modulated based on the blower speed.
