Method for utilization of enthalpy of evaporation of water in air conditioning apparatus of vehicle, involves comparing current blowing out temperature with certain maximum blowing out temperature of vaporizer

摘要

The method involves determining actual gradient of absolute water content of discharged air using dew point of air at output of a vaporizer. The dew point of air at the output of the vaporizer is determined over air inlet temperature and humidity and current blowing out temperature of vaporizer. A desired maximum blowing out temperature of vaporizer is determined. The current blowing out temperature is compared with the certain maximum blowing out temperature, for enabling utilization of the evaporation enthalpy of the water for inner space refrigeration of a vehicle. Independent claims are included for the following: (1) device for utilization of enthalpy of evaporation of water for inner space refrigeration of vehicle; and (2) air conditioning apparatus.
