It now maintains operations in 80 countries and employs more than 131,000 people. In 1988, after two years of construction, the new headquarters for Bouygues Construction was officially opened for business. Named Challenger, the complex became a technological showcase for late 20th century architecture.Site InformationBouygues decided to convert their headquarters into an eco-conscious building by significantly reducing its energy footprint. The LG MULTI V Water system was chosen as the ideal HVAC solution for this project. The system not only saves energy but also reduces water usage as it recycles water in order to regulate the temperature of the building. With LG’s advanced technology, the building’s water consumption was reduced by more than 70 percent.LG SolutionBouygues ChallengerLG MULTI V Water Solution with Geothermal Application.REFERENCE SITEOUTDOOR UNITS REFERENCE SITE100 I 101Note 1.

2. 正文2.1 系统整体设计优化系统整体设计优化是VRV多联机系统中非常重要的一环，它涉及到整个系统的性能、效率和稳定性。
在实际工程中，系统整体设计优化可以通过以下几个方面来实现。
两面出风嵌入式的机型比较适合使用在较为狭长的空间，如办公室、走到。
天花板藏风管式可使用在狭长型空间、L型房间、挑高空间、小空间等场合。
薄型天花板藏风管式一般用在宾馆、住宅以及小型办公室。
落地暗藏式一般使用于层高较高、或层高较低但不适合吊顶的空间。
送风方式一般为上送下回。
壁挂式常用于面积较小、不适合做吊顶或不希望装变化的改造项目中。
2.2主机侧设备水源多联机室外机系统与风冷多联机室外机系统基本相同，都是由：换热器、压缩机、气液分离器、油分离器、四通换向阀、电子膨胀阀、电磁阀、压力开关、毛细管、压力传感器等组成。
但是与风冷多联机不同的是，水源多联机制冷时冷却介质是水，而不像传统风冷多联机的室外机那样冷却介质是空气。
因此，冷凝器结构形式不同，风冷多联机系统为强迫对流风冷冷凝器，一般采用肋片管式换热器。
水冷多联机系统为套管式水冷冷凝器。

水源侧系统一般水管路的系统形式有以下几种方式：1）夏季采用水源多联机，冬季采用集中式供暖。
2）夏季冬夏均采用水源多联机。
3）如过渡季节需要同时供热、供冷，水源侧系统可采用热回收式系统，如图四。

4.1骋望骊都项目本工程为骋望置业骋望骊都华庭住宅楼小区，总建筑面积为22万平方米，此次设计为会所，主要由活动室、茶室、健身房、泳池等组成。
关于水冷多联空调系统设计的探讨摘要：多联机是一种新型的空调系统，在我国得到了广泛的应用，它具有系统简单、舒适节能、设计灵活、安装简便而且可靠性较高等优点，已经成为了国内的空调领域当中一种较为重要的空调系统。
通过与风机多联空调系统的对比，结合工程案例，总结出水冷多联空调系统的一些特点，以及设计工程中的一些注意事项。
关键词：风冷多联空调系统水冷多联空调系统特点注意事项1.水冷多联空调系统的原理多联机空调系统按外机冷却形式主要分为风冷多联机和水冷多联机两种。
这两种形式的空调系统的循环原理大致相同，其工作原理是：由控制系统采集室内舒适性参数、室外环境参数和表征制冷系统运行状况的状态参数，根据系统运行优化准则和人体舒适性准则，通过变频等手段调节压缩机输气量，并控制电子膨胀阀等一切可控部件，保证室内环境的舒适性，并使空调系统稳定工作在最佳工作状态。
两者主要不同的地方就是室外机的换热介质存在着一定的差异。
在水冷多联空调系统运行的时候，风冷多联的室外机的换热介质是空气，而水冷多联的室外机系统的换热介质是水。
由于水冷多联空调系统有独特的换热器结构，在对相同热量进行交换时就会让水冷换热器的面积减少很多。
所以，水冷多联系统的室外机的体积相对来说比较小，安装比较方便灵活。
2.水冷多联空调系统的特点2.1传统的风冷多联机由于连管长度限度，无法应用到高落差的建筑物上，而水冷多联空调以水管连接，基本无管长限制，尤其适用于高层建筑或大型楼宇。
同时由于采用水作为冷热源，主机无需与室外空气直接换热，因此基本不用考虑散热问题，可方便的设置在当层或者集中放置在设备机房内，大大的提高了建筑的空间利用率，且无需开百叶，不会对建筑外立面的美观性造成影响，震动以及噪音小。
2.2水冷多联空调系统采用水来冷却，冷凝温度低，COP能效高达5.8，节能效果明显，运行费用低。
2.3水冷多联空调系统可实现内外区分，可满足现代建筑物在同一时间不同区域制热和制冷的需求，系统通过温控阀切换其工作状态；当系统冷负荷为主要负荷时，自动启动冷却塔进行散热；当系统热负荷为主要负荷时，自动开启锅炉提供热源；当冷热负荷基本相等时，冷却塔和锅炉都无须开启，即通过热回收便可满足空调要求，避免产生多余的电费，并且当冷热平衡时，热回收的效率最大。
