notes

Common methods of modulating this water temperature include controlling the cooling tower fans or using a cooling-tower bypass pipe. Controlling the cooling tower fans, either by cycling fans on and off or by using a variable- speed drive on the fans, allows the system to control the temperature of the water leaving the tower sump. The diverting valve on the cooling-tower bypass pipe diverts warmer water leaving the condenser and mixes it with cooler water from the cooling tower to modulate the temperature of the water entering the condenser.

Each of these options has the effect of varying the temperature of the water entering the condenser, ensuring an acceptable condensing pressure and temperature.

Another example is a system that must start and operate during cooler weather. The cold tower water would force the condensing pressure down to the point where the system could not operate. In this example, the temperature of the water entering the condenser is controlled by a diverting valve and a cooling- tower bypass pipe.

If the entering water temperature causes the condensing pressure to become too low, the valve begins to divert the warm water that is leaving the condenser and mixes it with the cool tower water, producing a controlled water temperature entering the condenser. In this example, by diverting 65°F [18°C] water leaving the condenser and mixing it with the 40°F [4°C] tower water, the condenser is provided with 55°F [13°C] condensing water. This warmer condensing water results in a higher condensing pressure.
