For the efficient operation of the cooling and dehumidification system

the relationship between dehumidification and the inlet air speed

dry bulb temperature

and relative humidity of evaporator is numerically analyzed. The results show that

when inlet air temperature and humidity are kept constant

dehumidification capacity increases first and then decreases with an increase in the inlet air speed. When the moisture content and the speed of the inlet air are constant

the dehumidification capacity gradually decreases with an increase in the dry bulb temperature of the inlet air. When the dry bulb temperature of inlet air is between 21-36 ℃ and its relative humidity is between 40% and 85%

the difference between the wet bulb temperature of inlet air- and its evaporation temperature at the optimum COP is about 10 ℃. There is a nearly linear relationship between the corresponding evaporation temperature at the optimal COP and the evaporation temperature with the maximum dehumidification capacity. After compared with the test data

it shows the error of the numerical model is less than 10%.
