In airports and subway stations, the ambient temperature is typically maintained at comfortable levels thanks to large scale air conditioners. Because of the heavy demand of these locations, cooling tower systems need to be paired with the central air conditioning system.

• Many subway stations are surrounded by residential areas, so noise should be stringently controlled.
• The space between the air outlet and the ceiling should be considered.

Based on the many years of experience in producing heat-rejection devices, Liangken recommends using square shape crossflow cooling tower which can be easily combined with multi sets to satisfy cooling requirements for large water flow. The notable thing is that the air inlet of the cooling tower should not be blocked and the height should be above 3m from buildings during the installation of the evaporative cooling system.
