空调机组盘管冻裂的根源及防治方法

空调机组盘管冻裂的根源及防治方法

发布日期:2018-04-09 作者:地源热泵公司 点击:

为了防止风机盘管冻裂现象的发生,通常我们会对其做保温处理,甚至加设局部防冻采暖。但冻裂事件仍然时有发生,给很多人造成了严重的损失。根据原因,大致有以下几点:

In order to prevent the occurrence of cracking phenomenon of fan coil, we usually do the heat treatment, even adding local heating antifreeze. But the cracking events still occur, causing serious losses to many people. According to the reasons, there are roughly the following points:

1、脏堵。

1, dirty plugging.

脏堵是比较常见的一个问题,一般造成脏堵的物质为铁屑,尘土,泥沙,杂草。通常为了保持水质的稳定性,系统中需加入适量的六偏磷酸钠,但热水中还是很容易溶入少量氧气,久而久之造成金属管道和设备腐蚀而产生铁锈。

Dirty plugging is one of the most common problems. Generally, the dirty materials are iron filings, dust, sediment and weeds. Usually in order to maintain the stability of water quality, the system needs to add a proper amount of six sodium hexametaphosphate, but the hot water is easy to dissolve into a small amount of oxygen, the passage of time caused corrosion of metal pipes and equipment and rust.

2、气堵。

2. Gas block.

气堵也是一种比较常见的问题,通常造成气堵的原因有以下几点:

Gas block is also a common problem, usually caused by gas plugging for the following reasons:

清洗充水阶段部分空气未被排出;供热阶段水中溢出的空气及蒸发的水蒸气;由多次更换水质而导致系统中气体含量的增加;部分排气阀自动部件损坏,排气系统不理想。

Part of the air is not discharged during the filling stage; the water overflows and evaporates in the heating stage; the increase of the gas content in the system is caused by the repeated replacement of the water quality; the part of the exhaust valve is damaged automatically and the exhaust system is not ideal.

3、室外气温的影响。

3. Influence of outdoor air temperature.

在建筑物不同部位,所对应的气温不同,加上北侧缺少阳光照射,所以相对温度较低,容易冻裂。

In different parts of buildings, corresponding to the different temperatures, with the lack of sunlight, so relatively low temperature, easy cracking.

4.管理疏漏。

4. management oversight.

不能忽略管路中的水流声;重视压力表的偶尔较大幅度波动;各阀门应处于正确的开(闭)状态。

The water flow in the pipeline can not be ignored; attention should be paid to the occasional fluctuation of the pressure gauge; the valves should be in the right open (closed) state.
