One technique they're experimenting with is so-called "dew-point cooling," which relies on the natural energy produced by evaporating water, rather than fossil fuels.

With the use of frozen water units, modular units and natural cooling system for HIMOD flagship series will have the obvious effect for the energy saving.

A hydraulic computation equation for water distribution sytem of counterflow type natural draft cooling tower has been established by applying Bernoulli Equation.
