艾默⽣-PEX空调技术参数说明投标货物型号及主要技术参数说明⼀、前⾔针对机房空调市场不断发展的现状，为了提⾼我司机房空调在市场上的竞争能⼒，满⾜客户⽇益严格的性能要求，公司推出了 Liebert.PEX 系列机房空调产品，该系列产品在⾼可靠性、灵活性、⽣命周期内节能等⽅⾯具有明显的市场竞争优势。
Liebert.PEX 系列产品是基于艾默⽣全球研发与设计平台的⾼端机组，针对全球销售，全球同步上市。
⼆、整机系统说明Liebert.PEX 系列空调产品在送风⽅式上分为上出风和下出风两类产品，在系统配置上分为风冷型、⽔冷型、⼄⼆醇冷却、冷冻⽔型。
上送风机组外观下送风机组外观1、容量说明Liebert.PEX 系列机组增加了⼤容量机组，最⼤容量机组 P3100 制冷量达到了 100kW （8.6 万⼤卡），。
2、制冷系统配置说明为了加强 Liebert.PEX 机组在市场上的竞争能⼒，除了在⼤容量机组上采⽤双压缩机制冷系统外，也推出了⼤容量单压缩机制冷系统的机组，单压缩机系统最⼤制冷量达到了 53kW ，具有很强的市场竞争⼒。
在产品性能⽅⾯ Liebert.PEX 机组的单压缩机⼤容量系统 P2045 和 P2055 采⽤双风机双电机系统结构，使送风系统的功能更强⼤，调节范围更宽。
当机房有多台机组同时使⽤时，单系统机组可以作为⼀个模块来应⽤，不会影响整个机房的整体性能。
关于压缩机、风机数量，以及结构、冷量、主机尺⼨的描述见下表。
下表中的冷量数据为风冷、⽔冷机组下送风机型的数据，除冷量数据外，其它数据与上送风机型相同。
Liebert.PEX 系统描述简表3、风机系统机组送风机外余压可以根据⽤户要求进⾏⾮标调整，对于风帽送风机外余压标准为25Pa，地板下送风标准为75Pa，对于风道送风产品标准送风压⼒为100Pa，风压调整范围为25～200Pa。
超过200Pa 的风压要求请提前向公司申请。
4、电加热器加热量标准为⼀级，在需要增加加热量时可以增加第⼆级加热器。
