How Evaporative Cooling Works

Nature-inspired cooling that’s green, clean, and renewable.

Dry air energy refers to the amount of energy (cold) that unsaturated air tends to be saturated. It is expressed as the difference between the enthalpy value corresponding to the dry bulb temperature of dry air and the enthalpy value corresponding to the dew point temperature of dry air.

When you walk along the beach, the cool sea breeze brings relaxation. At the edge of a waterfall, you feel nature’s magic — coolness and freshness from water evaporation. JHCOOL harnesses this natural process.

Our evaporative air coolers use a wet curtain system. Hot air passes through the moist pad, water absorbs heat, and the outgoing air becomes cool, moist, and fresh — all without harmful refrigerants.

“

Before installing the JH air cooler, we were using traditional ammonia refrigeration. Electricity cost exceeded 15,000 per year. In 2013, introduced by friends, I learned about JHCOOL’s reputation. After visiting their factory and seeing the cooling effect, I installed 20 units. The advantages: energy saving, environmental protection, cooling, and dust removal.
