Knowledge Base

Q

The design of a closed cooling tower water circulation system requires a comprehensive consideration of multiple factors. ###System composition It mainly consists of an inner loop and an outer loop. Internal circulation refers to the flow of cooling medium (such as process water) inside the coil to remove heat; External circulation refers to the spraying of water outside the tower, which absorbs heat through contact with coils and evaporates to dissipate heat. ###Design points 1. * * Traffic calculation

Q

The control system of a 100 ton closed cooling tower mainly consists of the following parts: -* * Temperature control * *: Real time monitoring of cooling water temperature through temperature sensors. When the water temperature is higher than the set value, the control system will automatically increase the fan speed or turn on more fans to accelerate air flow and enhance heat dissipation; After the water temperature drops to a certain extent, the fan speed decreases or some fans are turned off
