| 요약1 |
본 연구에서는 부산시내의 업무용빌딩 5개소를 방문하여 부하계산 결과에 의해 결정된 부하량 그리고 할증률 및 안전율 등을 고려하여 선정된 열원장비의 용량과를 비교하고 또한 각 냉열원장비의 용량별 가동시간 을 일일정비 가동현황을 분석하여 비교함으로써 장비의 적정 용량에 대한 기초자료를 제공하고자 하며 장비선정 과정에서 고려하여야 할 요소들에 관하여 고찰해 보고자 한다. |
| 요약2 |
The basic factors determining the amount of energy used in office buildings are the weather conditions and building factors. But the real energy consumer is central plant equipment such as boilers and chillers that produce thermal energy for heating and cooling. Inaccurate decision of the primary equipment's size can cause a high initial-cost, an excessive equipment space, a wasted energy by low operation-efficiency and shortening of the machine's life.In this reason, the decision of optimal size for a central plant equipment is very important. There are several factors for the decision such as an orientating factor, a safety factor(equipment factor), piping losses and simultaneous usage factor applied in the sizing process except a basic cooling load. But there is no standard method for applying those factors. Usually, factors are applied individually by experience or custom of each engineer.In this study, the authors emphasize the meaning and the problem of those factors, examine them by analyzing factors which was applied to actual practices, and propose the recommendation value of safety, load, operation factors and application methods. |
