The sealake water air conditioning AC work at CEL and related efforts by others are summarized, along with annotated references. Computer models for estimating the capital costs and energy use for sealake water air conditioning AC systems are introduced, and the output from these models exercised on two Naval facilities are presented. It was found that 1 the computer models produced reasonable estimates of the capital cost and energy use of seawater AC systems 2 the capital cost and energy use of such systems are sensitive to the pipeline length, which is dependent on the seawater temperature near the seafloor 3 at a hypothetical typical Naval facility represented by the average of the two trial facilities, seawater AC requires 80 less energy than conventional AC, but the capital cost of seawater AC is 60 greater and 4 at this typical facility the life cycle cost for seawater AC is 25 less than that of conventional AC. Sealake water AC is recommended for consideration as an alternative to conventional AC at Naval facilities that adjoin bodies of water, and it is also recommended that the computer models be used to make estimates of the capital cost and energy use of sea or lake water AC systems.
