습공기선도를 이용한 실내환경 초기분석

A MS Windows based program is developed to analyze indoor environment using psychrometrics. This program uses the fundamental equations of psychrometrics, specifically the inter-relationships between various thermodynamic properties of atmospheric air. Various thermodynamic parameters such as, relative humidity, wet-bulb temperature, enthalpy, and specific volume are illustrated in the form of constant lines with the variable barometric pressure. In addition, the seasonal indoor comfort zone for the summer and the winter are also illustrated. The collected data of any indoor space using a computerized data logger can be directly imported to the program, and can be used to analyze the indoor environment and HVAC systems.
