  空调机组采用全空气空调系统。新风由室外新风管引入，经过初效过滤后在净化空调机组内与室内回风混合，混合后的空气处理到送风要求后送入办公区域。

    监视初效空气过滤器状态，过滤器设置风压差开关，压差开关动作设定值在0~300Pa范围内可调整，当过滤器前后压差⊿P>设定值时，压差开关动作，系统产生报警信号，提醒管理人员进行更换或清洗；

送风机运行状态、故障监测显示，取送风机配电盘里触点作为风机运行状态信号，当触点闭合时风机运行，触点断开时风机停止；

监控新风温度、送风温度、送风湿度、室内温度和室内湿度。

监视送风机和排风机运行状态，故障报警，手自动状态。

2、控 制 内 容：

    2.1、根据回风温度设定值，调节表冷器电动调节阀开度，以使室内温度保持设定要求值。
    2.2、空调机组停机时让水阀有20%的开度，保证空调机组在使用前能对房间进行预冷（夏季）或预热（冬季）；

    2.3、新风阀与送风机连锁，风机停止时自动关闭新风阀。

    2.4、电加热与风机连锁保护，如果风机未开启，不能开启电加热

    2.5、电加热过热保护功能，设送风温度高温报警，例如：当送风温度高于40度时强制关闭电加热。

    2.6、采用新风温度作为盘管防冻的参考温度，在冬季时，当盘管温度值低于设定值时,自动开启水空调阀门，停止新风机组，关闭新风阀，并中央主机报警；

    2.7、频率控制:根据设定好的送风压力，自动调节变频器频率。
