Figure 36  Isometric 01 – Chilled Water Cooling

The system distributes chilled water to several buildings in a desert environment. 

During periods of extreme temperature, stand-by equipment may be brought into operation.


The calculated solution shows the flows and pressures throughout the system for normal operation when the following are all fully operational:


   2 x Air Cooled Liquid Chillers

   2 x Chilled Water Pumps

   3 x Air Handling Units

   1 x Fan Coil Unit


'Stand-By' equipment not in operation:


   1 x Air Cooled Liquid Chiller

   1 x Chilled Water Pump

   3 x Air Handling Units

   1 x Fan Coil Unit


Appropriate pipes have been closed to isolate the 'Stand-By' parts of the circuit.
