请教,空调室外机不运行。 室内风扇工作正常。怎讲?

我觉得,由于室外温度较低时,冷却液不会吸收很多的热量,所以无需室外风扇启动降温冷却液。空调机工作原理毕竟与热泵不同。空调只是简单地输送室内热量由冷却液降温。

理解错误。
 
我家空调风扇真的是气温低时就不工作,气温回升时,就自动启动了。开始我也怕空调坏了,毕竟我家空调已经二十年了,每年天气刚开始热,我会试着启动空调系统,看看空调有没有问题,室外温度低于25摄氏度时,我把空调设在22度强制空调工作,就有这样的室外风扇不启动的情况出现。今年天气冷热变化大,也时常会有这样的空调在工作,感觉到出风口有冷气出来,室外风扇不工作的情况出现。


谢谢,如果我的空调也是这个情况就好了。 请问你还记得当时的室内温度是多少?

那是不可能的。

空调室外机没有温控系统,就是开和关,跟压缩机连动。

我是根据事实推论的,当我打开空调后,室内出风口有冷气了出来,上午趁天气凉爽,出去散步回家,看了空调室外风扇一眼,发觉风扇没有工作,赶紧进屋检查空调状态,出风口还有冷气出来。到了中午天气炎热了,再去查看风扇已经是嗡嗡嗡地运转中。所以我推测当气温不高时,室内温度也不是很高,冷却液没有承载太多的热量,因而风扇没有被启动散热。
 
If your AC unit isn't turning on, start by checking the thermostat, circuit breaker, and air filter. If those are all in order, consider the indoor shut-off switch, a tripped fuse, or potential wiring issues. If the problem persists, a faulty compressor or other component might be the culprit, requiring professional assistance.

Here's a more detailed breakdown:

1. Check the Thermostat:
  • Ensure the thermostat is set to "cool" and that the temperature is set lower than the current room temperature.
  • Verify the thermostat is functioning correctly, including checking batteries if needed.
    • If the thermostat screen is blank or not displaying correctly, it may need new batteries.
2. Inspect the Air Filter:
    • A dirty or clogged air filter can restrict airflow, preventing the AC from turning on.
    • Replace the filter if it's dirty or heavily clogged.
3. Check the Circuit Breaker:
    • Verify the circuit breaker for the AC unit isn't tripped.
    • Reset the breaker if it's tripped and ensure it stays in the "on" position.
4. Check the Indoor Shut-Off Switch:
    • Make sure the indoor shut-off switch (often mistaken for a light switch) isn't in the off position.
    • If it's in the off position, flip it back to the on position.
5. Look for a Tripped Fuse:
    • Check for a blown fuse, especially in the unit's shut-off box at the outside unit.
    • If a fuse is blown, it needs to be replaced.
6. Inspect Wiring:
    • Look for frayed, damaged, or loose wires, especially in the thermostat and unit's wiring.
    • Ensure all wires are securely connected.
7. Consider Other Potential Issues:
    • Low Refrigerant: If the AC is running, but not cooling effectively, it could be a sign of low refrigerant, which can prevent the unit from turning on.
    • Compressor Failure: A burnt-out or failing compressor motor can prevent the AC from turning on.
    • Clogged Drain Line: A clogged condensate drain line can also prevent the AC from turning on.
    • Faulty Capacitor: A failing capacitor can prevent the AC from starting.
8. When to Call a Professional:
    • If you've checked all of the above and the AC still isn't working, it's best to contact a qualified HVAC technician.
    • Electrical problems, compressor issues, and refrigerant leaks should be handled by professionals.

我知道我的前述话语看似不可能,可我家的实际情况就是这样。我家设置的空调温度比较高,25摄氏度,风扇设置“on”,室内空气有流动就会感觉舒服很多,这样设置是为了不让室内外温度差别过大。出风口出来的风是由锅炉自身的风扇带动的,与室外风扇无关,室外风扇只是起到冷却冷却液的作用。有一年我们启动了空调,觉得出风口出来的风不是很冷,后来发现原来冬季罩室外风扇的套子没有卸掉,把罩套取了,立即冷风就来了。
 
正常情况室外机风扇不会长时间不转,基本应该处于运转状态。如果不转,也基本是有问题。
另外,在制冷模式下,如果设定的目标温度是20摄氏度,那么出风口的温度应该会达到15摄氏度甚至更低,看看出风口温度。
 
如果风扇在on上而不是Auto,风扇应该一直转,与空调启不启动没关系了。空调没启动你也觉得风是凉的那是因为地下室的冷空气循环到室内。
 
风扇一直on的好处是可以平衡整个房子的湿度,不至于地下室太潮湿。我是设到每小时开15分钟
 
鼓风机设在"自动"。
 
风扇设在自动,空气交换机也可以启动风扇。也就是风扇启动不一定非要空调启动。
