【摘要】 本文提出建筑物的室内负荷分布不均匀性的描述方法,在此基础上利用多联机空调系统仿真平台,以制冷工况下室内机连续运行的多联机为对象,研究室内负荷不均匀性对多联机系统部分负荷特性的影响规律。指出在室内外环境参数不变的条件下,多联机空调系统在部分负荷下的COP是由负荷率和负荷不均匀指数两个参数决定的一个"性能域",并分析性能域存在的原因。更多还原

【Abstract】 The description methods of the indoor load distribution are presented in this paper. Based on the simulation platform of Multiple-split air conditioning (MSAC) system, the part load performances of MSAC system under different indoor load distributions are studied. As a result, it is found that when the indoor and outdoor conditions (temperature and relative humidity) keep constant, the system COP will be within a "performance domain" related to the system load ratio and the indoor load unevenness index. Then it further analyzes the factors which influence the shape of performance domain.更多还原
