Evaporative cooler - Wikipedia
Direct evaporative cooling (open circuit) is used to lower the temperature and increase the humidity of air by using latent heat of evaporation, changing liquid water to water vapor. In this process, the energy in the air does not change.
Evaporative Cooling 101 | EVAPCO
Direct evaporative cooling. Direct evaporative cooling systems put the process fluid, typically water, into direct contact with air. Water flows through fill as a fan draws air across it, facilitating the transfer of heat from the warm water to the cooler air.
Direct vs Indirect Evaporative Cooling: What is the Difference
2023年4月26日 · In a direct evaporative cooling system, water evaporates into the air stream through the engineered pad to offer the cooling effect. But, an indirect evaporative cooling system uses evaporating water to cool the airstream passing through the heat exchanger.
Evaporative Cooling - The Engineering ToolBox
In a direct evaporative cooling system - outside air is pulled through a water-saturated medium (typical cellulose) - or air is sprayed with water - and cooled by evaporation. The cooled air is circulated by a blower. Moisture can be added to the air stream until saturation.
Understanding Direct Evaporative Cooling Units: Energy-Efficient ...
