대학 건물에서 히트 펌프 냉난방 시스템의 경제성 분석

Abstract

This research is a thing about a LCC analysis to Heat Pump system of university building by reduction of electric power costs for education and incentive. Produced details item different expense of EHP and GHP equipment construction step and preservation administration step. Analysis result is as following. 1) Substance discount rate in LCC analysis of target system to apply in variable item of necessary expense equipment construction step and preservation administration step has calculated. Substance discount rate calculated by 2.87% as result that calculate taking advantage of existing data of fixed deposit interest and prices of commodities geometrical ration etc. 2) Executed LCC analysis for target system after lowering whole curriculum reduction of electric power costs for education. Analysis result, energy cost-cutting effect of EHP appears greatly than GHP unlike existent study finding, EHP decided by economical system. 3) Sensitivity analysis executed by incentive 500,000 won per units and geometrical ration of gas expense by 1%. As a result, because lowering effect of electric charges appears greatly, EHP decided by more economical system than GHP. As research result of front is different from existent study finding, EHP by lowering of electric charges for alteration and education of governmental frequent volunteer system was decided by more economical system than GHP. If energy expense in LCC increases by scale increase of target building, deflection is expected to be big. Hereafter, energy guideline of government dimension, support system and many reviews about fare system and research are judged to need by solution way for national energy supply and demand's problem and efficient utilization. This research is as result that is refuted in diffusion activation policy of gas cold room for existing cold room electric power substitution effect. Therefore, systematic volunteer system and thesis of standard of diffusion policy of government dimension are considered to need.
