User's manual for the IIHR model of dry-wet cooling tower economics

Technical Report ·
OSTI ID:7302895

This manual provides brief, easy-to-read, and easy-to-follow directions for the use of an IIHR computer model for determining the economics of a specific type of dry-wet cooling tower. The cooling system represented by the model consists of a separate mechanical, induced-draft ''dry'' tower of the indirect type and a mechanical, induced-draft, crossflow ''wet'' tower, each with its own fans receiving air in parallel. They are connected in a series water flow with the dry tower placed first, the wet tower next and a surface condenser receiving cold water from the wet tower and supplying hot water to the dry tower. The model considers operation of the system in all three possible modes: dry cooling only, wet cooling only, or both dry and wet cooling, and uses the lowest-cost mode for each set of meteorological conditions and power loading.
