태양열을 활용한 천정형 공조기 부하운전 특성 평가

Abstract

In recent years, it is common to satisfy the thermal comfort and productivity of workers because the workers need to improve the work environment in industry. The air-conditioning system in industry, most equipment involve the factors that make it difficult to heating design because of the thermal load, high heights and the shortage of the installation space. In existing design, we carried out design by intuition and experience of the designer in large span , But it is necessary to realize the problem in large span and to consider the developing air quality and thermal environment according to requirement of workers about environment improvement. Also, at the moment, people use the fossil thoughtlessly, so it happened the shortage of energy resource. In order to alternate it, the world has focused the development. of renewal energy. Of them, the solar thermal system is used easily despite of low cost and short study period and is available in a various field. Nowadays, the solar thermal energy is mostly used for domestic hot water system to heat floor with water. But, there needs a lot of hot water when it applied to hot water heating system, and the equipment also becomes huge. So, it needed the alternative system. In this study, in order to replace the existing system, it considers the characteristics about the large span and it installed the solar thermal system with solar collector and thermal storage in ceiling space and it performs heating through the air-handling unit.
