    (1)每台净化机组均配置一套两通调节阀,一套温、湿度探头,该两通调节阀设置于机组回水总管上,温、湿度探头设置于手术室回风总管上,温、湿度探头采集到信号后传递给DDC,DDC再通过所设定的温度来控制两通调节阀的开启度。
    (1) each purification units are equipped with a set of two valves, a temperature and humidity sensor, the two valve is arranged on the return pipe unit, temperature and humidity of air duct on the probe set in the operation room, the temperature and humidity probe collected signal transmitted to the DDC, DDC through the set temperature to control the two valve opening.
    (2)DDC实行湿度优先控制,在夏季工况下:新风表冷器先进行一次降温除湿,新、回风混合后在空气处理机组上进行二次降温除湿,直到湿度满足DDC设定的标准,这时DDC再通过辅助电加热器工作来达到设定的温、湿度。冬季工况下,由湿膜加湿器对空气进行加湿,使湿度满足要求。
    (2) DDC implementation of humidity control in summer, under the conditions of air cooler: a first cooling dehumidification, new, mixed air after the air handling unit two cooling dehumidification, until the humidity meet the DDC standards set by DDC, then the auxiliary electric heater work to achieve temperature and humidity setting the. In winter, humidification of air is made by wet film humidifier to satisfy the requirement of humidity.

    (3)辅助电加热器的开关程序通过DDC来控制,当风管内的空气温度小于所设定的温度时电加热自动打开,反之则关闭,电加热器本身还带有过热保护装置,当其温度超过90度时,电加热器自动关闭。
    (3) switching auxiliary electric heater is controlled by DDC, when the wind pipe of the air temperature is less than the setting temperature of electric heating automatically open, and closed the electric heater itself with overheating protection device, when the temperature exceeds 90 degrees, the electric heater automatically shut down.
    (4)新风净化机组与空气净化机组实现连锁控制,即系统内只要有一台空气净化机组打开,其对应的新风净化机组必须先打开,只有当共用该新风系统的空气净化机组全部关闭时,所属新风净化机组才能关闭。
    (4) the chain control unit and air purification air purification unit, namely the system as long as there is an air purification unit is opened, the corresponding air purification unit must be open, only when sharing the new air system air purification units are closed, belongs to the air purifying unit shut down.
    (5)排风机与空气净化机组实现连锁控制,即空气净化机组打开,其对应的排风机就开始工作,只有当共用该排风系统的空气净化机组将全部关闭时,所属排风机才能先关闭。为了保证手术室的正压,建议甲方在非手术室时段将新风机及排风机开启。
    (5) chain control machine and air exhaust purification unit, air purification unit is opened, the exhaust fan starts to work, only when the common exhaust system air purification unit will be fully closed, the exhaust fan can be shut off. In order to ensure the positive pressure in the operation room, it is recommended that party a open the new air blower and exhaust fan in the non operation room period.
