Composite Flow Closed Circuit Cooling Tower
I. Overview
Closed-loop composite cooling towers, sometimes abbreviated as composite closed towers, are named for the mixing of spray water with hot air. The spray water flows downward from above, with the wind divided into two paths: one part of the cool air flows downward from above, and the other enters horizontally from the side, exchanging heat with the descending spray water through the packing, thereby reducing the temperature of the spray water.
Comprised mainly of heat exchange coils, spray irrigation water system, exhaust system, and frame housing.
Section II: Process of Operation
The spray pump draws water from the sump, pumps it to the upper part of the heat exchange coil, and sprays it in an umbrella shape through nozzles, covering the external surface of the pipe material continuously and evenly, forming a thin water film. Part of the water absorbs the heat energy of the high-temperature refrigerant inside the pipe, converting it into latent heat of vaporization, evaporating into a gas state. The refrigerant inside the pipe is cooled and condensed or cooled down, while the water that does not evaporate falls back into the spray water sump.
The ventilation system features a top-mounted fan designed for intake. It draws air from inside the tower and exhausts it outward. Cool, dry air outside the tower enters the tower through the heat exchanger coils and the intake grates. It flows downward through the coils from the top, carrying away the evaporated water vapor and increasing the humidity and temperature of the air. Additionally, cold, dry air is also drawn in on the tower's side, where it exchanges heat with the descending spray water through the packing. The two warm, moist air streams are eventually exhausted outside the tower by the fan.
In the spray trough, a float valve is installed. When the water level is low, it automatically replenishes the supply to maintain a consistent water level in the trough.
III. Working Principle
The working fluid (water, oil, or other liquids) flows through the coil, with the coil exterior wrapped in spray water. Heat from the fluid is transferred through the tube walls, forming saturated steam with water and air. The heat is then exhausted into the atmosphere by a fan. During the recirculation process, the spray water is cooled through PVC finned radiators, creating cold water that flows in the same direction as the fresh air. The coil primarily relies on the湿热 heat conduction method. A key feature of the composite closed-loop cooling tower's working principle is its ability to significantly inhibit the formation of scale on the coil exterior.
