Special Issue Information

Dear Colleagues,

As terminal cold sources, large-scale cooling systems are widely used in thermodynamic systems, especially in thermodynamic power stations with conventional, nuclear, or solar energy. With the increasing need for energy and water savings, as well as carbon and drainage reduction, cooling processes and technologies have attracted widespread attention thanks to their crucial impacts on the safety, economy and environmental friendliness of thermodynamic processes. Comprehensive studies on cooling systems would lay good foundations for the development of innovative cooling processes and technologies with high cooling efficiency, low water consumption and good intelligence. This Special Issue provides a forum for authors to present novel studies on cooling theory, processes, technology, apparatus, and systems, as well as comprehensive reviews on state-of-the-art developments in cooling systems. Topics of interest for publication include, but are not limited to:

  • Once-through cooling system;
  • Mechanical draft cooling system;
  • Natural draft wet cooling system;
  • Natural draft dry cooling system;
  • Direct air cooling condenser;
  • Dew Point indirect evaporative cooling system;
  • Solar cooling system;
  • Aerodynamic field reconstruction;
  • Heat transfer intensification;
  • Plume abatement;
  • Water saving and drainage reduction;
  • Energy saving and anti-freezing;
  • Intelligent diagnosis and operation.

Thermal power units play a crucial role in the deep peak regulation of power generation. During deep peak regulation, the load of the unit changes significantly, causing fluctuations in the inlet water temperature of the cooling tower and the water temperature in the filler. Therefore, in cold regions in winter, cooling towers have a high risk of freezing, which threatens the economic and safe operation of the unit. This paper establishes a three-dimensional numerical model based on constant heat dissipation and explores the average and minimum water temperatures at the bottom of filler under different water distribution methods, crosswind velocities, and ambient temperatures. The results show that the water distribution method has a significant impact on the water temperature at the filler bottom. Reducing the water distribution area can significantly increase the minimum water temperature at the filler bottom and reduce the risk of freezing. Although the presence of crosswind is not conducive to the cooling performance of the cooling tower, the higher the crosswind velocity, the higher the minimum outlet water temperature at the filler bottom and the lower the risk of freezing. The minimum water temperature at the filler bottom is approximately linearly related to the ambient temperature and is less affected by the unit load at the same temperature. Full article
