The cooling tower selection must have the following four parameters:
- Circulating water flow Q (m3/h) (or the matched host parameters, the cooling water flow Q of the cooling tower can be obtained by calculation);
- Inlet water temperature t1;
- Outlet water temperature t2;
- Wet bulb temperature τ.
Common formulas for selecting cooling towers with known basic parameters:
Cooling water volume = host cooling capacity (KW) × 1.2 × 1.25 × 861/5000 (m3/h)
Cooling water volume = host condenser heat load (kcal/h) × 1.2/5000 (m3/h)
Cooling water volume = host condenser heat load (m3/h) × 1.2 (m3/h)
Cooling water volume = host cooling capacity (cooling ton) × 0.8 (m3/h)
Cooling water volume = heat load of main engine evaporator (kcal/h) × 1.5 × 1.25/5000 (m3/h)
Cooling water volume = heat load of main engine evaporator (m3/h)×1.2×1.25 (m3/h)
Cooling water volume = heat load of main engine evaporator (cooling tons) × 1.2 × 1.25 × 3024/5000 (m3/h)
Note: 1.2 is the selection margin and 1.25 is the condenser load factor.
Example: The cooling capacity per 1 million kcal of lithium bromide host is:
Working condition ①: inlet temperature 37.5℃; outlet temperature 32℃; wet bulb temperature 28℃, (cooling water flow rate: 300~330m3/h), 350-400T cooling tower should be selected;
Working condition ②: inlet temperature is 37°C, outlet temperature is 30°C, wet bulb temperature is 28°C, (cooling water flow rate: 248m3/h), 450T tower should be selected.
