If we are unaware of the actual process (i.e) humidification and cooling, it is clear from the term "evaporative cooling" that the process must involve addiction of latent heat for evaporation and removal of sensible heat that is cooling.

Latent/Sensible Heat extended definition. Latent and sensible heat are types of energy released or absorbed in the atmosphere. Latent heat is related to changes in phase between liquids, gases, and solids. Sensible heat is related to changes in temperature of a gas or object with no change in phase.

@Sai.
Sensible heat means the change in temperature without change in phases.
Sensible heat means the change in temperature without change in phases.

Let us take a simple practical example of refrigerator. In freezer section (called as evaporator) refrigerant enters in liquid state and exits in gaseous state. To convert ammonia from liquid to gaseous state we add first sensible heat (subcooled liquid to saturated liquid) and then we add latent heat which converts it saturated liquid to gaseous form.

Sensible Heat: Q=mCp ΔT.
where, m=mass flow rate
Cp=Heat capacity at constant pressure
ΔT = Temperature Const.
where, m=mass flow rate
Cp=Heat capacity at constant pressure
ΔT = Temperature Const.

For cooling process we have to remove the sensible heat and for humidification we have to give the latent heat.

Can anyone tell me how to convert chlorine from liquid to gas?

Sensible change in temperature of gas is the latent heat required to vaporise the liquid and process is also known as adiabatic saturation, and temperature of gas is adiabatic saturation temperature or wet bulb temperature.
