1、 - 摘要南京某中型办公建筑面积3610 m2，建筑物高度23m，地上主体建筑六层，框框架结构，室内外高差0.8m。空调建筑为一小型建筑，选用多联机VRV3空调系统；它集变频、变容等技术于一身，具有使用节能、舒适、控制、灵活等特点，通过包不同容量机组的组合和布置可以满足不同规模建筑物的要求，特别是在小于10000平米的舒适性空调系统内。VRV空调系统全称为Variable Refrigerant Volume系统，即变制冷剂流量系统。系统结构上类似于分体式空调机组，采用一台室外机对应一组室内机（一般可达16台）。控制技术上采用变频控制方式，按室内机开启的数量控制室外机内的涡旋式压缩机转速，进行
2、制冷剂流量的控制。 VRV空调系统与全空气系统，全水系统、空气水系统相比，更能满足用户个性化的使用要求，设备占用的建筑空间比较小，而且更节能。该系统采用网络控制，变频多联机运行状态可以通过LONWORKS或BACnet网关接口上传信号至建筑物自控中心BAS或BMS系统，自控中心经该网关口下传信号至变频多联机设备，从而实现对整个空调系统的管理。网络控制的功能：室温监视、运行状态监视、压缩机运行状态监视、室内风扇运行状态、空调报警信息和错误代码、ON/OFF控制和监视、温度设定和监视、空调机模式设定和监视、遥控器模式设定和监视、滤网信号监视和复位、风向设定和监视、遥控器禁止设定。关键词：VRV、变
