2种典型的多联机空调设计方案在深圳某办公楼的应用分析与能耗对比

The Comparison of Energy Consumption and Application Analysis on Two Typical Design Schemes of VRF System in One Office Building in Shenzhen

多联机空调系统以其良好的适应性、节约建筑空间、施工安装方便的特点被越来越多的新建、改建建筑所采用。论文以深圳某典型办公楼为研究对象,分析了2种典型的多联机空调系统的设计方案,并对这2种方案的能耗进行了详细计算与对比。结果表明:该项目在相同的冷负荷与相同的室外、室内环境条件下,集中设置顶出风多联机空调系统,比在每层分散设置侧出风小型多联机空调系统全天能耗更低,且节能率为26.6%.

VRF system is being used by more and more new-built and remodeled buildings because of it's great adaptation, space-saving and easy installation. Taking a typical office building in Shenzhen as the research object, this paper analyzes two typical design schemes of VRF system, and makes detailed calculation and comparison of the energy consumption of the two schemes. The results show that under the same cooling load and the same outdoor and indoor environment, the project centralizes the ejection air VRF system, which has lower energy consumption and 26.6% energy saving rate than the small VRF system with side-outlet air on each floor.
