Why is a return pipe needed in a circulating water tank?
Thread Content
Our company’s circulating pool is equipped with a return pipe; having just the return pipeline is sufficient – why is it necessary to have an additional return pipe?
This return pipe can regulate the temperature of the circulating water, especially in areas with large temperature differences in cold regions.
We usually don’t use it; when the temperature of the circulating water drops, the fan can be turned off, which not only raises the water temperature but also reduces energy consumption
The methods for adjusting water temperature are as follows: 1. Adjustment of the fan blade angle； 2. In systems with multiple turbines, it is possible to increase or decrease the operation status of individual units ； 3. Use the short route for return water, rather than spray cooling. In cold and frigid regions, using the return flow from a near-path circulation in conjunction with fan blades at a small angle can achieve fine-tuning effects. It is a control method that primarily selects the appropriate control measure based on changes in atmospheric temperature and return water temperature. For reference.
