Theoretical research on air cooling dehumidification process

Analyses the air cooling dehumidification process in the surface air cooler and the variation of the coefficient of performance (COP) of cold source with evaporation temperature. Presents an ideal air cooling dehumidification process. Gives a mathematical expression of the air specific enthalpy in the cooling dehumidification process. Establishes a polynomial equation and differential equation of the comprehensive energy efficiency ratio (EER) of cold source in the ideal air cooling dehumidification process. Obtains the maximum of EER, and plots the curves of the variations of both the air specific enthalpy and the humidity ratio with the dry-bulb temperature.
