空气能出现高压保护故障主要原因在制冷剂充注量过多以及截流过大或者排气温度过高，高压端蒸汽量大排不掉所造成的。<br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">

空气能出现低压保护故障主要原因在制冷剂充注量不足或泄露以及截流过小，低压端在气液两相状态时缺液所造成的。</span></p>

① 0℃以下结霜。<br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">
② 0℃以上化作水。<br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">
③ 水流淌下来，汽化，而在化霜过程中，翅片上的水还有没有完全汽化干净,机组又进入了下一轮制热程序，机组又开始结霜，而霜就成冰了。空气中残留下来的是霜，而翅片上残留下来的水在低于0℃时就形成冰了。<br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">
<br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">
<strong style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"> 4、怎样除霜？</strong><br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">
① 应用小循环系统使机组得到休息。缩减其化霜的时间，同时能保证蓄热水箱有足够温度的热水，并且确保能效比的提高。<br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">
② 四通阀转向，把制冷变成制热，蒸发器上有霜，让系统反过来工作，蒸发器变成冷凝器，让加热的水把霜化去，这是一种常用的方法。空调化霜也是采用这种方法。</span></p>

④最简单最原始控制除霜的方式是定时除霜，大约40分钟左右，机组就进入除霜阶段，无论有霜无霜，照常工作，这种除霜控制简单而且成本低。<br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">
⑥定时除霜加温度除霜加湿度除霜。<br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">
<br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">
<strong style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box !important; word-wrap: break-word !important;"> 5、如果停水空气能的电源插头要不要拨掉？</strong><br style="margin: 0px; padding: 0px; max-width: 100%; font-family: "microsoft yahei"; font-size: 14px; line-height: 28px; box-sizing: border-box !important; word-wrap: break-word !important;">
不需要，一般所有的承压式水箱容器的热水设备在停水的时候都没有必要把电源拔掉，承压式的工作原理是运用水本身的压力由一端进，再由另一端被水的压力挤出，基本上进水压力和出水压力几乎相近，而出水压力的损失是由于水在容器和管道的阻力所造成的。</span></p>
