The choice of switching the cooling method of a glass fiber cooling tower from outdoor to a specific temperature point directly affects the system's cooling hours. Assuming the calculated water wetness required to end air conditioning at this moment is 12.7°C, considering the cooling tower's cooling range, pipeline, and heat exchanger losses, which cause the water temperature to rise by 4.5°C, it can be determined that the cooling tower cooling method can be switched to when the outdoor wet bulb temperature is equal to or below 8.2°C.

After selecting the glass fiber cooling tower in the system based on the summer cooling load and outdoor wet bulb temperature, it is also necessary to verify its cooling capacity under the cooling tower's cooling mode.

In indirect cooling systems, plate heat exchangers should be selected. Compared to traditional tube-and-shell heat exchangers, plate heat exchangers have superior heat transfer capabilities.

In direct chilled water systems, a bypass should be installed for the chilled water pump in the cooling water loop. When using cooling towers for chilled water supply, the chilled water pump is turned off, and the cooling water bypasses through the chilled water pump. At this moment, the circulation water power is supplied by the chilled water pump. Therefore, when planning the system, consideration should be given to changing the chilled water pump.

In direct chilled system planning, it is crucial to emphasize the sterilization and filtration of cooling water to prevent blockage of the terminal coils.

Considering that the cooling tower's cold amplitude (the difference between the outlet water temperature of the cooling tower and the outdoor wet bulb temperature) decreases with the increase in the scale of the cooling fillers under specific outdoor wet bulb temperatures and building loads, it is feasible to use a series configuration of cooling towers in a multi-tower system to enhance the cooling effect. This method can improve the outdoor changeover temperature for the cooling tower's cooling mode and subsequently increase the duration of cooling supply.

Glassfiber Reinforced Plastic (GRP) Cooling Tower manufacturers take into account that the primary function of cooling towers for cooling is during the winter, when filtration is most needed. Therefore, in regions with lower temperatures during winter, anti-freezing equipment should be installed in the cooling water system, such as setting auxiliary pipes or adding heaters.

Our Glass Reinforced Plastic (GRP) Sewage Covers are suitable for various industries including oil, chemical, urban sewage treatment, food, metallurgy, compound fertilizer, and light textile dyeing. They offer excellent effects in odor control and anti-corrosion insulation. What are the product's notable features?

1. Strong Corrosion Resistance: This product is manufactured using acid and alkali-resistant, corrosion-resistant resins as the base material, with an excellent curing formula and advanced curing process. Based on the specific conditions and shapes of each wastewater pond, a particular mold is confirmed for the outer mold curing and shaping process.

2. Cost-effective and Long-lasting: Compared to other wastewater treatment deodorization solutions, it offers lower costs, simpler installation, and a longer service life.

3. Lightweight and High-Strength, Easy to Install: The glass fiber gas collection hood has a density only 1/3 to 1/4 that of steel products, with high curing degree and heavy load-bearing capacity, offering high strength. It is suitable for large-span pool structures. Additionally, the lid can be divided into several small pieces for easy transportation and installation.
