数码涡旋多联式空调系统冬季运行特性实测
Field test of operating characteristics of DVM systems in winter
摘要：
研究了数码涡旋多联式空调系统的冬季运行状况和节能性能，分析了影响系统小时平均供热性能系数HHPF的主要因素，得到了系统HHPF随室内机开机率、室外环境温度和室内设定温度的变化规律以及数码涡旋多联式空调系统部分负荷运行特性。通过计算每个工况点压缩机运行容量百分比，分析了室内机开机率和室外环境温度对压缩机运行容量百分比的影响。

Abstract：
Studies operating characteristics and energy consumption of the DVM (digital variable multi-unit) air conditioning system，analyses influencing factors of HHPF(hourly heating performance factor), and obtains the variety patterns of HHPF with the indoor-unit on/off ratio, outdoor temperature and indoor set temperature, and performances under partial loads. With the calculation of compressor output ratio of each testing condition, analyses the impact of the indoor-unit on/off ratio and outdoor temperature on the compressor output ratio.
