A dual spray nozzle type cooling tower is provided to extract moisture contained in the atmospheric air of high temperature and high humidity, which passes through fillers, by low temperature water sprayed by second spray nozzles, thereby preventing generation of a large amount of water bubbles like white smoke when the air is discharged to the outside. A dual spray nozzle type cooling tower includes an outer body(3) formed with an atmospheric air inlet at the lower part, and a suction fan(5) for inhaling the atmospheric air into the outer body. A plurality of first spray nozzles(7) spray cooling water transferred from an indoor unit(10) of a central cooling system. Fillers(9) absorb the sprayed cooling water. A water collecting tub(19) collects the cooling water passing through the fillers. A plurality of second spray nozzles(21) spray low temperature water over the fillers. A low temperature water tub(25) is connected to the second spray nozzles via a low temperature water supply pipe(27) and receives the low temperature water. A pump(26) is mounted to the low temperature water supply pipe for boosting the water stored in the low temperature water tub to the second spray nozzles. The water collecting tub is mounted with a water level sensor and connected to a recovery pipe(29) of the water tub, wherein the recovery pipe is mounted with a pump(28) for transferring the water collected in the water collecting tub to the low temperature water tub. |
