摘要(Abstract):

通过对夏热冬冷地区数码涡旋多联式空调系统制热运行的试验研究,得出了室内机小时制热量、系统小时耗功和小时供热性能系数随室内温度和室外温度的变化规律,小时供热性能系数随部分负荷率的变化规律,并对除霜工况进行了分析。
The operating characteristics of DVM air-conditioning system under heating condition in hot summer and cold winter zone is studied by experiments.The variation of indoor unit hourly heating capacity,hourly energy consumption of the system,and the hourly heating performance factor(HHPF) with indoor and outdoor air temperature are obtained.Meanwhile,the influence of part load ratio to hourly heating performance factor(HHPF) is analyzed.The operating characteristic under defrosting condition is obtained,too.
