  • 如何避免层流手术室新风空调机组盘管被冻?
    来源:http://www.sdyhrs.com 浏览: 发布日期:2019-07-01
    冬季北方寒冷地区新风空调机组常出现盘管冻裂问题,这样严重影响手术室的正常维护,下面层流手术室装修公司就给大家总结一下防止层流手术室新风空调机组盘管被动的几个技巧!
    In winter, the problem of coil freezing crack often occurs in fresh air air air conditioning units in northern cold areas, which seriously affects the normal maintenance of the operating room. The following laminar flow operating room decoration company will summarize some skills to prevent the passive coil of fresh air air conditioning units in laminar flow operating room.
    盘管冻裂主要有以下几个方面的原因:一、新风空调机组停止工作的情况下,机房内没有采暖措施,温度低于-0℃以下,系统水泵停止工作,并且新风空调机组盘管内没有放水,或盘管设计不合理盘管内的水放不干净,又或是新风密闭阀关闭不严等;
    The main reasons for coil freezing crack are as follows: 1. When fresh air air conditioning unit stops working, there is no heating measure in the room, the temperature is below -0 C, the system pump stops working, and there is no water in the coil of fresh air conditioning unit, or the water in the coil is not clean or new when the coil design is unreasonable. The air-tight valves are not closed properly.
    二、新风空调机组正常工作的情况下,空调水系统设计的水力失调,水流量不足,或是盘管水量设计偏小,又或是双冷源蒸发温度对水盘管的影响等。对于新凤空调机组停止工作的情况下解决新风机组防冻的措施有:在施工时建议院方在机房内设置采暖设施;在冬季到来之前,将新风空调机组冷盘管内水放干净,定期检查新风密闭阀的关闭情况,发现关闭不严及时修理;在空调机组定购时选择有排空设计的冷水盘管,并设置停机保温防冻装置(见图8)。
    2. Under the normal working condition of fresh air air conditioning units, the design of water system of air conditioning is out of balance, the water flow is insufficient, or the design of coil water flow is too small, or the influence of evaporation temperature of double cooling sources on coil water. For Xinfeng Air Conditioning Unit to stop working, measures to solve the freeze prevention of fresh air units are as follows: during construction, the hospital is advised to install heating facilities in the machine room; before winter comes, the water in the cold coil of fresh air conditioning unit is cleaned, the closure of the fresh air sealing valve is checked regularly, and timely repair is found to be improper; When ordering air-conditioning units, cold water coils with exhaust design are selected, and freeze-proof devices for insulation and freeze-proof are installed (see Fig. 8).

    对于新风空调机组正常工作的情况下解决新风机组防冻的措施有:在空调水系统设计时进行水力计算,避免水力失调及水流量不足的问题;在新风机组进风处设置新风电预热,将新风预热到5℃。由于新风空调机组冷盘管冻裂现象出现比普遍,也引起空调机组厂家的重视,在新风空调机组的设计上也有不错的措施:如新风机组组采用新风旁通设计、冷水盘管为顺流式设计(见图9)、双冷源新风空调机组内的表冷器与蒸发器的布置、蒸汽盘管破真空阀、疏水阀的安装等。
    For the normal operation of fresh air air conditioning units, the measures to solve the freeze prevention of fresh air units are as follows: hydraulic calculation is carried out in the design of air conditioning water system to avoid hydraulic imbalance and insufficient water flow; fresh air power is preheated at the intake of fresh air units, and the fresh air is preheated to 5 C. As the phenomenon of freezing crack in the cold coil of fresh air air conditioning units is more common, it also attracts the attention of air conditioning units manufacturers. There are also good measures in the design of fresh air conditioning units, such as new air bypass design for fresh air units, downstream design for cold water coils (see Fig. 9), surface cooler and steam in double cold source fresh air conditioning units. Arrangement of generator, installation of steam coil breaking vacuum valve and trap, etc.
