The purpose of this study is to evaluate the air diffusion performance of a range of indoor units for room airconditioners; the wall-mounted type, floor-standing type, and ceiling-mounted type. These types of units, which have been widely used in housing spaces, will be studied with respect to thermal comfort and the energy performance using CFD analysis. In this study, current air conditioning status and related problems in housing spaces are examined, and a CFD analysis is performed in order to compare and analyze the thermal comfort and energy efficiency across each type of indoor-unit using the PMV, ADPI, EUC and FCEI indexes. The analysis results collectively considering thermal comfort and energy performance indicated that the ceiling-mounted type 4-way indoor unit showed the best diffusion performance in terms of thermal comfort, and had the second best diffusion performance in terms of energy performance after the wall-mounted type under certain conditions.

In this study, the influence of energy factors on energy consumption in a selected office building is analyzed by sensitivity analysis. Dominant energy factors of each building and system are determined. Then, the energy management schemes for these factors are suggested. If this method is applied to other office buildings, it may be possible to work out a strategy of energy diagnosis and retrofit more efficiently.

Recently, As the residential building becomes large-scale and high-rise, the water supply pressure go up. The water hammering is problem on cold & hot water manifold system by quick closure of valve. It bring on junction vice-leakage and damage of machinery and tools. It is required to a appropriate solution in occurring water hammering and discomfortable use of cold & hot water manifold system on account of the difference of water supply pressure on top and bottom floor. Thus, the purpose of this study is to present plan data for performance improvement of cold & hot water manifold system through finding out factors of cold & hot water system and evaluating performance cold & hot water manifold system with piping network analysis.
Mock-up 실험을 통한 고층 주거건물 급수?급탕 헤더시스템의 유량 밸런싱 방안에 관한 연구

Today in residential buildings, cold & hot water supply system is composed of boiler, pipe, and faucet and so on. That is the equipment function with one system. Specially, high-rise residential buildings bring on discomfortable use and unexpected conditions on account of faucet outlet pressure rise and the difference of water supply pressure between top and bottom floor. Cold & hot water manifold system introduces positively for supplying cold & hot water more stably from residential buildings. But, the plan data is insufficient for manifold system. If water pressure is not appropriate, it loses the function of water supply system. The researches became accomplished which solve the problems about difference of water pressure between top and bottom floor and unbalance of flow rates with introduction of many water supply system and vertical zoning methods. But, the researches leave something to be desired about decrease of water pressure and flow rate or change of hot water supply because of simultaneous waste flow rate in a household. Thus, the purpose of this study is to present flow balancing plan data for performance improvement of cold & hot water manifold system through evaluating performance of alternative plans with mock-up test.

Recently the domestic apartment must maintain water pressure and secure flow rates pertinently according to going on high-rise and high grade. Specially, cold & hot water manifold system introduces positively for supplying cold & hot water more stably from residential buildings. But, the plan data is insufficient for manifold system. If water pressure is not appropriate, it loses the function of water supply system. When water pressure is high too much, equipments are damaged and occurred noise and vibration by water hammering. Thus, the purpose of this study is to evaluate performance of piping types for water supply pressure as analyzing the change aspect of pressure, flow rates and temperature simultaneously in use through piping network analysis.

As the structure, material and construction of building develop continuously, so the recent residential buildings are being large, high-rise and group. High-rise residential buildings consume a lot of energy on supplying cold and hot water. As well, high-rise residential buildings bring on discomfortable use and unexpected conditions on account of faucet outlet pressure rise and the difference of water supply pressure between top floor and bottom floor. Thus, the purpose of this study is to research on using conditions of cold and hot water supply system through field measurement in high-rise residential buildings and to analyze problems.

본 연구에서는 대공간의 동계시 인체발열에 따른 실내온열환경의 변화를 실측하고 난방조건 및 외부환경과 관련하여 대공간에서 형성되는 실내온열환경의 특성을 파악하는 것을 목적으로 한다. 본 논문에서는 대공간의 실내수직 및 수평온도분포, 객석의 온도분포, 실내표면온도분포, 객석의 풍속분포, 실내온열쾌적성 등의 실내온열환경을 검토한다. The purpose of this study is to grasp the characteristic of indoor thermal environment from large enclosures in connection with heating condition and outdoor environment. This study has measured indoor thermal environment in accordance with heat loads from occupant for large enclosures in winter. We examined indoor thermal environment of the large enclosures in this study which include temperature distribution vertical, horizontal, seat and surface and thermal comfort environment.
