1, the cooling tower design of meteorological conditions
atmospheric pressure:P =99.4×103 kPa
Dry bulb temperature:θ =31.5℃
Wet bulb temperature:τ =28℃(Square and ordinary type are 27 degrees centigrade)
The cooling tower design parameters of 1. standard type: the inlet water temperature of 37 degrees, the column temperature is 32 C.

2, the temperature of inlet water temperature: 43 degrees Celsius, the column temperature is 33 C.

3, high temperature, inlet water temperature of 60 DEG C, the column temperature is 35 C.

4, ordinary type: the inlet water temperature of 37 DEG C, the column temperature is 32 C.

5, a large tower: the inlet water temperature of 42 degrees, the column temperature is 32 C.

6, cooling water Q (m3/h)
Needless to say, when the cooling water tower will be selected to calculate the coefficient multiplied by 1.15 can be.

7, the import column temperature
An important parameter selection of cooling tower, cooling tower tower type design standard of civil case as the water temperature is 37 degrees centigrade, the water temperature is 32 degrees Celsius, and the tower is 5 DEG C; industrial cooling tower design is generally divided into 65 DEG -45 DEG, 43 DEG -33 DEG, 40 DEG -32 DEG and other files, import temperature of 8 tower -20 oc.

8, the wet bulb temperature (T c)
The cooling tower backwater and the water temperature difference is generally called cooling range it mainly depends on the wet bulb temperature of the surrounding air. Effect of cold water cooling tower outlet temperature and inlet temperature difference or wet bulb temperature close to the measured value. Therefore. Local variations of wet bulb temperature directly influences the cooling effect of cooling tower.

9, dry bulb temperature 0 (c)
The air cooling tower is used to realize the air conduction heat dissipation is mainly affected by the air dry bulb temperature. Because the air dry bulb temperature is higher, the specific heat, heat absorption capacity is limited, and the cooling efficiency is low, therefore, need the air cooler with large surface area, so that the high cost of air cooler.
