Dry Air Cooling to Cool Glycol Mixed Water

Dry Air Cooling to Cool Glycol Mixed Water

Using dry air cooling to cool glycol-mixed water is a common method in various industrial processes and HVAC (Heating, Ventilation, and Air Conditioning) applications. Dry air cooling systems employ air as the cooling medium without the need for evaporative cooling or direct contact with water. Here's how it works:

1. Heat Exchanger (Air-to-Water): In a dry air cooling system, there is a heat exchanger designed to transfer heat from the glycol-mixed water (or any other process fluid) to the ambient air. The glycol-mixed water, which carries heat from a process or a cooling loop, flows through the tubes or channels of the heat exchanger.

2. Airflow: Ambient air is drawn into the dry air cooling system by fans or blowers. The airflow can be natural or forced, depending on the application and cooling requirements. The air is directed over the surface of the heat exchanger.

3. Heat Transfer: As the ambient air passes over the heat exchanger's surface, it absorbs the heat from the glycol-mixed water within the tubes or channels. Heat transfer occurs as the warm process fluid gives off heat to the cooler air, causing the fluid to lose thermal energy and lower its temperature.

4. Discharge of Heated Air: The now-heated air is expelled from the system into the surrounding environment. In some cases, the discharge air may be directed upward to minimize its impact on nearby structures.

5. Cooling Effect: The process is continuous, and the glycol-mixed water's temperature gradually decreases as it flows through the heat exchanger. The cooled glycol-mixed water can then be recirculated through the cooling loop to remove more heat from the process it serves.
