Using multiple regression method, establishes mathematical models for air coolers and fan coils respectively and obtains their performance equations under large tempe rature difference conditions. Quantitatively analyses the influence of chilled w ater with large temperature difference on cooling capacity and dehumidifying eff ects of air coolers and fan coils.
