In terms of water quality, what should I pay attention to? If the water quality of the local water source is not suitable for the underground wet curtain air cooler, the corresponding technical measures can be taken to meet the requirements. The commonly used solutions are as follows:
1. Sand remover and sedimentation tank
When the water content in the water source is high, a cyclone sand remover can be installed in the water supply pipeline to reduce the sediment concentration in the water. If the project site is relatively large, it is also possible to build a sedimentation tank to remove sand. The sand removal cost of the sedimentation tank is lower than that of the sand remover, but the floor space is large!
2, water purification filter
Some water sources have a large turbidity, you can install a water purification filter to prevent the surface area of the heat exchanger!
3, high quality heat exchanger
Since most of the groundwater has a high degree of salinity and hardness, it is necessary to use a heat exchanger with a good material quality. When the salinity of the water source is 350~500mg/L, a stainless steel plate heat exchanger can be installed. When the water source salinity is greater than 500mg/L, a corrosion-resistant titanium plate heat exchanger or a volumetric heat exchanger should be installed in the system.
