cooling tower capacity

Dear Moideen

What is the power consumption for 450 Ton chiller it may be around 270 to 275 kW. If it is so then the nominal capacity of cooling tower required will be around 422 TR (528 THR). In other words you might be having 6% margin in cooling tower capacity.

The design wet bulb temp is 86 F and in summer you say it goes to 88 F. This will reduce the cooling tower capacity by around 17 to 20%. Or your condensing temperature will shoot up by 2 F. This will increase the power required for the chiller and condenser heat rejection.

dear , CHILLER COP is .8kw/ton.so the electrical power is 360kw on full load.considering the peak wetbulb temp.shoul be increased 25% higher capacity(450*1.25).
