Air cooler ventilation method:
There are two ways of air cooler ventilation: blast and induced air.
①Blow-type air cooler: The air first flows through the ventilator and then into the tube bundle.
②Induced-draft air cooler: The air first flows through the tube bundle and then into the ventilator.
The operating cost of the former is more economical, the generated turbulence is beneficial to heat transfer, and it is used more. The latter has a uniform airflow distribution, which is conducive to precise temperature control and low noise, which is the direction of development.
The outlet temperature of the hot fluid is mainly controlled by adjusting the air volume through the tube bundle, that is, adjusting the inclination angle of the blades, the rotation speed of the fan, and the opening degree of the shutters.
For fluids that are easy to condense and freeze in winter, hot air circulation or steam heating can be used to adjust the fluid outlet temperature.
