Heat source temperature is the core factor of the salt-water separation.
The HP's cold side temperature and power, the thermal
energy acquired by the droplets, and the evaporation intensity
all increase with the growth of the heat source temperature. Decreasing
cooling water temperature has limited influence on the
evaporation intensity when the heat source temperature is
relatively low. The heat source temperature is also the key factor
of the equilibrium pressure in the evaporator.
