A Study on analyze of energy saving rate by retrofitting multi air-conditioner from conventional type to high efficient type using Energyplus

Energyplus를 이용한 고효율 멀티에어컨디셔너의 에너지절감 효과 분석

The objective of this study is to analyze the energy saving rate by retrofitting multi air conditioner from conventional type to high efficient type using Energyplus 4.0 which was developed for simulating a building energy by D.O.E. Generally, Multi air conditioner system was installed for both the cooling and the heating in a building. However, it was difficult to estimate the energy saving rate in the case of retrofitting multi air conditioner from conventional type to high efficient type. In the present study, annual energy consumptions of them were evaluated for same building and climate condition.
