Abstract
Use of heat from seawater could be different from the weather conditions of a coastal city and seawater temperatures near the city. It will be a good option to use surface layer water with Heat Pump system for using seawater cooling/heating in Jeju. The study investigates the proper depth for seawater heat gain of Jeju area in Korea. Sampling points are 0, 10, 20, 30m from the surface of the Sea. Seawater temperature does not change significantly according to the depth in winter, while the temperature is quite different according to the depth in summer. In this study, it is analyzed to compare existing system and seawater heat source system for target buildings on Jeju. And this systems are calculated a initial cost.
