Air-cooled tower
Definition: The temperature difference between the inlet and outlet water. For industrial cooling towers, the typical range is 10–25°C (at a wet-bulb temperature of 28°C)7; for civil‑use cooling towers, the typical range is 5–8°C.

Basic Performance Parameters
Cooling water temperature difference (ΔT)
Definition: The difference between the inlet water temperature and the outlet water temperature. Typical ranges for industrial cooling towers are 10–25°C (at a wet-bulb temperature of 28°C)7, while for residential cooling towers they are 5–8°C.
Cooling water volume
Unit: cubic meters per hour (m³/h). This directly determines the size of the tower. For example, in industrial applications, typical ranges are 700–1000 m³/h.

Environmental Adaptability Parameters
Wet-bulb temperature (τ)
Design basis: The performance of the air-cooled tower is referenced to τ = 28°C; actual selection requires correction.
Cooling range index: the difference between the outlet water temperature and the wet-bulb temperature is ≤5°C (high-efficiency model).
