에너지 절약을 위한 공조기 운전 프로그램 개발 소개

A program that could analyze AHU operation and provide an energy conservation measure is developed. This program makes it easy to understand AHU operation by visualizing it on a psychometric chart. The goal of the program is to propose a method of conserving energy by predicting supply air temperature (SAT) and relative humidity. This program is written in C++, and the prediction is made through an R Program. The program has three screens, and their respective functions are: 1)　Operation?View: The AHU operation status can be viewed in real time on the psychometric chart, and historical data for AHU operation can be verified.　2) SAT Prediction?View: The SAT for a 24-hour period can be viewed, and the predicted SAT of the next 12 hours can be displayed as a graph.　3) OAF(Outdoor air fraction) & ECM(Energy Conservation measure)?View: The status of OAF of the past 12 hours and the energy efficient OAF of the next 12 hours is displayed. Through this program, energy conservation during the operational stage can be expected.
