I. Overview

Composite closed-loop cooling towers, sometimes abbreviated as composite closed towers, are named due to the mixing of spray water and hot air. The spray water flows from top to bottom, while the wind is divided into two paths: one part of the cold air flows from top to bottom, and the other enters horizontally from the side, crossing with the falling spray water through the packing to exchange heat and lower the temperature of the spray water.

Comprised mainly of heat exchanger coils, spray water system, exhaust system, and frame shell.

II. Process:

The spray pump draws water from the water tank, pumps it to the upper part of the heat exchange coil, and sprays it in an umbrella shape through nozzles, covering the outer 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 material is cooled and condensed or cooled down, while the water that does not evaporate falls back into the spray water tank.

The exhaust system features an intake-type top fan, drawing air from inside the tower and expelling it outward. Cool, dry air outside the tower enters the tower through the heat exchanger coils and the inlet grille. It flows downward from the top of the heat exchanger coils, carrying away the evaporated water vapor, thereby increasing the humidity and temperature of the air. Additionally, cold, dry air is also drawn in from the side of the tower, where it exchanges heat with the descending spray water through the packing. The two parts of warm, moist air are finally 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 working principle is its ability to significantly inhibit the formation of scale on the coil exterior.
