Abstract

The cost of electricity is very high in most of the Pacific Island Countries. Also, being tropical countries, they require a considerable amount of energy to condition hot and
humid climate conditions to the required human comfort conditions. Increase in the number of buildings with development makes it necessary to find new air conditioning
techniques. Seawater air-conditioning (SWAC) is a relatively new concept that utilizes water from the deep ocean where the temperature is considerably lower (typically 4-7oC) to provide cooling to buildings. Moreover, deep seawater has vast minerals and resources that can be used for quaculture, desalination, and energy production. This project focuses on feasibility study and design of a seawater air-conditioning system for USP Tuvalu campus. The first phase of the project included a feasibility check to see if the necessary resources are available, which included the measurement of seawater temperature at different depths, estimation of the total air-conditioning load for the USP Tuvalu campus using
CAMEL software, and sizing the major components of the system.

The second phase of the project included sizing the chilled water loop components for lab testing of a scaled-down model of the campus, the calculation of ductwork and the air
handling unit, dimensional analysis of model and construction and testing of the model and its cooling, and finally a study of the economic viability of seawater air conditioning of the USP Tuvalu Campus.
