為了防止風(fēng)機(jī)盤(pán)管凍裂現(xiàn)象的發(fā)生，通常我們會(huì)對(duì)其做保溫處理，甚至加設(shè)局部防凍采暖。但凍裂事件仍然時(shí)有發(fā)生，給很多人造成了嚴(yán)重的損失。根據(jù)原因，大致有以下幾點(diǎn)：

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、臟堵。

1, dirty plugging.

臟堵是比較常見(jiàn)的一個(gè)問(wèn)題，一般造成臟堵的物質(zhì)為鐵屑，塵土，泥沙，雜草。通常為了保持水質(zhì)的穩(wěn)定性，系統(tǒng)中需加入適量的六偏磷酸鈉，但熱水中還是很容易溶入少量氧氣，久而久之造成金屬管道和設(shè)備腐蝕而產(chǎn)生鐵銹。

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、氣堵。

2. Gas block.

氣堵也是一種比較常見(jiàn)的問(wèn)題，通常造成氣堵的原因有以下幾點(diǎn)：

Gas block is also a common problem, usually caused by gas plugging for the following reasons:清洗充水階段部分空氣未被排出；供熱階段水中溢出的空氣及蒸發(fā)的水蒸氣；由多次更換水質(zhì)而導(dǎo)致系統(tǒng)中氣體含量的增加；部分排氣閥自動(dòng)部件損壞，排氣系統(tǒng)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、室外氣溫的影響。

3. Influence of outdoor air temperature.

在建筑物不同部位，所對(duì)應(yīng)的氣溫不同，加上北側(cè)缺少陽(yáng)光照射，所以相對(duì)溫度較低，容易凍裂。

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聲；重視壓力表的偶爾較大幅度波動(dòng)；各閥門(mén)應(yīng)處于正確的開(kāi)（閉）狀態(tài)。

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.
