The Cooling System option determines the cooling technology. The following options are available:
•Once-Through: (This is the default.) Cooling water is withdrawn from a natural waterbody, passed through the steam condenser and returned to the waterbody. (See Water results for more details.)
•Wet Cooling Tower: Cooling water is recirculated through the wet tower and back to the condenser. The tower mainly relies on the latent heat of water evaporation to transfer waste heat to the atmosphere. (See Wet Cooling Tower or Wet Unit parameters and Wet Cooling Tower or Wet Unit results for more details.)
•Air Cooled Condenser: The air cooled condenser utilizes the sensible heating of atmospheric air passed across finned-tube heat exchangers to reject heat. (See Air Cooled Condenser or Dry Unit parameters and Air Cooled Condenser or Dry Unit results for more details.)
•Hybrid Cooling System: A hybrid cooling system consists of both wet and dry cooling units and uses a dry cooling unit as the primary cooling system and a wet cooling system just during the summer or a peak period, thereby reducing water consumption. This option is not compatible with the chemical looping CO2 capture technology. (See Hybrid Cooling System parameters and Hybrid Cooling System results for more details.)
