摘　　要：随着全球对可再生能源和环保意识的日益增强,光伏直驱变频多联机作为一种高效节能的空调系统,在办公建筑中的应用逐渐受到关注。然而,严寒地区的气候条件给光伏直驱变频多联机的运行带来了严峻的挑战。因此,对光伏直驱变频多联机系统在严寒地区办公建筑全年的运行情况进行实验研究。实验表明,系统在夏季某白天制冷的实验条件下,太阳能保证率为67.43%,COP_(c)为3.81;系统在冬季某白天供暖的实验条件下,太阳能保证率为56.79%,COP_(h)为3.23。对全年的运行数据进行分析,全年能源消耗效率(APF)数值为4.04,空调季节的太阳能保证率为50.26%,采暖季节的太阳能保证率为56.76%。光伏直驱变频多联机系统在严寒地区办公建筑运行时,能够较好地利用太阳能,减少电网侧的能耗。With the increasing global awareness of renewable energy and environmental protection,the application of photovoltaic direct-driven VRV system as an energy-efficient air-conditioning system in office buildings is gradually gaining attention.However,the climatic conditions of severe cold regions bring severe challenges to the operation of photovoltaic direct-driven VRV system.Therefore,this study conducts an experimental study by examining the year-round operation of a photovoltaic direct-driven VRV system in an office building in severe cold region.An experimental study was conducted to investigate the year-round operation of a photovoltaic direct-driven VRV system in office building in severe cold region.The experiments show that the system has a solar guarantee of 67.43% and a COP_(c) of 3.81 under the experimental conditions of daytime cooling at a certain time in summer,and a solar guarantee of 56.79%and a COP_(h) of 3.23 under the experimental conditions of daytime heating at a certain time in winter.The analysis of the annual operating data shows that the annual energy consumption efficiency(APF)value is 4.04,and the solar energy guarantee is 50.26% for the air-conditioning season and 56.76% for the heating season.The photovoltaic direct-driven VRV system is able to better utilize solar energy and reduce grid-side energy consumption when operating in office buildings in severe cold regions.
