Spatial Distribution Characteristics of Internal Load and Analysis of Impact on Designing Air-conditioning Load in Office Building

Qi Zhang, Da Yan, Dandan Zhu

Abstract: By the daily experience and professional research, we found that the value of internal load is random. Thus, a difficulty arises when designing air-conditioning system, calculating the building load and sizing the equipment. After a survey in an office building, we found the characteristics of internal load distribution can be defined by a distribution function. Since cooling load is not sure in the designing phase, over sizing air-conditioning equipment has been a common practice in order to ensure occupants comfort. In the investigation, it has been analyzed the detailed characteristics of internal load and this paper will propose a new design method based on the distribution characteristics observed.
