퍼스날 컴퓨터에 의한 실내열환경과 에너지소비량 예측을 위한 시스템 시뮬레이션 프로그램의 개발

Abstract

Recently, most of buildings involving commercial building have been air-conditioning system, which realize comfort environment. Air-conditioning system, which was aimed to make cool or warm as required, has changed. In modern time, major emphasis is placed on keeping a building comfort and led to reduce energy costs. So, good system design only consummates well-controlled system. Good system design is based on the suitable system scheme, precise calculation of system load and prediction of annual energy consumption and indoor thermal environments. It is usually necessary to calculate system load precisely to design well. Recently, it tends to use personal computers among engineers during to time saving and precise calculation. Therefore, in the part of HVAC design, the rapid population of PC has been made to deepen importance of PC. And so, this study is intended to develop simulation program which enables to predict indoor thermal environment and energy consumption using PC: As follow, this is titled to ACLS/92. Given weather and operation conditions to model building and air-conditioning system, we can find the variable values of coil loads, radiation air-conditioning loads, indoors temperature and humidity through PC calculation. As a result, we can obtain as follows: 1. We can predict comfort thermal environment by simulating indoor surface temperature. 2. Considering mean efficiency of system enables to obtain precise energy consumption. Especially, on the base of variable indoor temperature and humidity energy consumption using this computer simulation program can be compared with that of traditional operating system.
