摘要：
In this paper, an economic analysis of systems adopted as the perimeter zone system in office buildings such as convector, fan coil unit(FCU) and fan powered unit(FPU) was performed, with the variable air volume(VAV) system applied in the interior zone. The initial cost of each alternative, such as the construction cost of the air conditioning system, was determined by planning and design, and energy cost as running cost was calculated on the basis of the energy consumption of each system using a computer simulation. Economic analysis was performed using life cycle cost(LCC), with the present value method for the air conditioning system in the perimeter zone. The results show that FPU is the most economical air conditioning system. When VAV is applied to the interior zone, LCC of the FCU is reduced by 6% and the cost of FPU is reduced 9% less than that of the convector system.
