【摘要】 水冷(热)变频多联空调(VRF)是近年来发展起来的一种新型产品,它运行效率高,节能性好。为评价该变频多联空调系统的能耗特征,在建筑能耗动态模拟软件EnergyPlus的基础上,开发了水冷(热)变频多联空调系统(water cooled/heated-VRF)的全年能耗计算模块,并在一典型的商业建筑模型基础上,与已有的常见的空调系统作了建筑物全年总能耗仿真比较。结果表明,在辅助设备及锅炉燃气能耗较大的情况下,空冷VRF系统比较节能,同时在冬季耗能较低的情况下,水冷(热)VRF系统与中央空调系统相比更为节能。更多还原

【Abstract】 Water-cooled/heated variable refrigerant flow (VRF) is a new kind of product. It has good performance of the energy saving. To evaluate energy consumption features of the new-generation system, an energy calculation module for the system was developed based on the dynamic building energy simulation program, EnergyPlus. A building energy comparison between the water-cooled/heated VRF system and other air conditioning systems was implemented, using a typical commercial building model. Simulation results show that because of the large energy consumption of the assistant equipments and the boiler gas for other systems, the air-cooled/heated VRF system is the most energy saving. If the heating load in winter is small, the water-cooled/heated VRF system will be more energy saving than the central air conditioning system.更多还原
