Abstract：
Compares the thermal calculation methods for surface air coolers including dry-bulb temperature efficiency method， wet-bulb temperature efficiency method， wet-dry cooling conditions equivalent method and so on from theory basement，calculation process and precision. The results show that the wet-dry cooling conditions equivalent method is clear in its physical meaning and is simpler in calculation process and has higher precision.
