Abstract
The air conditioner is a technology that cross-exchanges air inside and outside the building and improves the energy efficiency of the building. In addition, a technology for connecting a heat pump has been proposed to improve the temperature exchange efficiency of an air conditioner. In this study, the air conditioner system was divided into a model to which no heat pump was applied and a model to which a heat pump was applied; in addition, a numerical analysis model was constructed using the Peng-Robinson equation and the IDEAL equation. In the case of the applied environment, the results of the relative humidity of 35%, 40% and 45% were compared, and it was confirmed that there was a difference of about two degrees depending on the state equation used. In this analysis, the General (A) mode and Bypass (B) mode of the air conditioner process were analyzed using the Peng-Robinson state equation.
