Abstract
Evaporative cooling is energy efficient and environment protective. However, little research has been done on the simplified and applied thermo-technical calculation method. In order to improve the practicability and advantage of evaporative cooling unit, and make the unit manufacture standard, a thermo-technical calculation for a plate indirect evaporative cooling unit and a packing direct evaporative cooling unit are simplified by experiments base on engineering optimization theory. In the experiments, an optimal water-spraying density was gained for the packing direct evaporative cooling unit, with the aluminum foil packing specific surface area of 500m2/m3; as well as an optimal water-spraying density for plate indirect evaporative cooling unit, with primary air channel length of 4mm, and secondary air channel length of 6mm.
