The purpose of this study is to suggest the life cycle cost analysis of primary cooling system in service life. During the life cycle cost analysis of primary cooling system, the project phases divided into planning/design, equipment construction, maintenance/management, and demolition/sell phases. and established cost items of each phases.
The main results are as follows;
(1) The result of capacity base LCC10～LCC20 of primary cooling system indicates that the absorption chiller-heater system for urban gas is better for less than 600USRT, and ice storage method is better for more than 600USRT.
(2) In the LCC10～LCC20 of primary cooling system, the order of the average rates in each phases indicates maintenance /management, equipment construction, planning/design, and demolition/sell phases.
(3) In the LCC10～LCC20 of primary cooling system, of the influence factor of service life indicates energy cost, water service and drainage cost, operation labor cost, maintenance cost, tax, fire insurance cost, initial interest cost, demolition labor cost, construction waste cost, sale and remain cost.
