水冷直膨式空调机组与水冷多联机组合系统在地铁车站的应用分析

Application of water-cooled direct-expansion air conditioning unit and water-cooled VRF combination system to subway stations

以实际工程为例,提出了一种新的地铁空调设计方案,用水冷直膨式空调机组与水冷多联机系统取代冷水机组。与传统空调系统在初投资、运行能耗等方面进行了对比分析。结果表明,水冷直膨式空调机组与水冷多联机组合系统相比于传统系统,初投资增加约42.5%,节能率约为27.9%。

Taking a practical project as an example,a new air conditioning design scheme for the subway is proposed,in which the water-cooled direct-expansion air conditioning unit and the water-cooled VRF system are used to replace water chillers.The combination system is compared with the traditional air conditioning system in the initial investment and the operation energy consumption.The result shows that the combination system has an initial investment increase of about 42.5%and saves energy by about 27.9%compared with the traditional system.
