| Abstract |
The purpose of this study is to suggest the cost characteristics of process phase of project in life cycle cost analysis of primary cooling system. In order to select economical primary cooling system in early heat source plan stages, the research investigates cost items and cost characteristics during project process phases such as planning/design, construction, maintenance/management, and demolition/sell phases. The study also analyze the life cycle cost by capacity leading to suggest the most economical primary cooling system as well as develop life cycle cost rate characteristics in each project phase.
The main results are as follows;
(1) During the LCC analysis of primary cooling system, the project phases divided into planning/design, construction, maintenance/management, and demolition/sell phases. and established cost items of each phases.
(2) In the LCC analysis of primary cooling system, the order of the rates in each phases shows maintenance/management, construction, planning/design, and demolition/sell phases.
(3) The result of capacity base LCC15 of primary cooling system shows that the absorption chiller-heater system for urban gas is advantageous for less than 500USRT, and ice storage method is advantageous for more than 500USRT. |
