Detailed description of the cooling tower can be a combination of a combination of convenient ways to meet different application requirements, users can also make a decision based on a combination of site conditions, and in accordance with the characteristics of the building users to adjust the appearance of the tower. If the user space is very limited. I also can be designed for the special requirements of users, to meet user requirements for thermal performance and noise. Save power with small ventilation resistance filler and fiberglass wing designed by Tsinghua University for efficient fan cooling tower design, thereby reducing the motor is equipped with power, ultra-low-noise type with a motor power of smaller, more economical power, according to user requirements, equipped with two-speed motors to save power. This series of convenient modular design of the cooling tower, cooling tower adjacent air chamber separated from each other, can be under the premise of the normal operation of the cooling tower, maintenance repair, cleaning fillers, water pipes and water tank maintenance work more convenient.
