The use of cold seawater to replace water chilled by air conditioning and refrigeration compressors and their auxiliaries represents a cost effective savings applied to the largest single power in Waikiki. Of the 107 Megawatts used here, 51.4 are identifiable with air conditioning that is subject to energy reduction by the use of cold seawater. The project will consist of laying on ocean intake pipe a minimum of 48 inches in diameter approximately three miles offshore to a depth of 1680 feet. Water will be pumped to a machine room which will house a bank of titanium plate heat exchangers and salt water and chilled water pumps. Here the salt water will cool fresh water which will be circulated through a district cooling system to users in Waikiki. A second seawater pipe will return the slightly warmed water approximately one mile offshore. The scope of the work covered by this application is to specifically attain greater detail into this already well accepted general plan using advanced district cooling and DOE technologies already accepted, so that construction costs and economics can be accurately ascertained. The ultimate goal being to obtain construction financing and have this project become a reality. 21 figs.
