关于暖通空调系统和雨要知道什么

With all the recent precipitation, now’s a good time to go over the effects of rain on your heating and air conditioning system.

\r\n

Luckily, your outdoor HVAC units are designed to withstand harsh weather conditions, such as rain, snow, and even a little hail. Unfortunately, if there are bad weather conditions, you may have to wait for a technician to service your HVAC unit, especially if it’s on the roof.

HVAC Design

\r\n

Your air conditioner utilizes heat pump technology to pump heat from inside your home to the outdoor environment. The outdoor unit can either be an air conditioner or a heat pump capable of both heating and cooling.

\r\n

As a “split system,” one unit is located inside (evaporator coil and blower) and the other unit is located outside (compressor and condenser).

\r\n

Since the outdoor unit is exposed to the elements, it has been built to withstand extreme conditions. This is done by sealing electrical components from the rain and using sturdy, corrosion-proof materials, such as copper, aluminum, and plastics.

\r\n

Despite all the precautions, your HVAC system is still vulnerable to damage from falling tree limbs, wind-driven debris, flooding rains, and salty air.

\r\n

Regular maintenance, which includes a full cleaning, is the best way to ward off costly repairs and improve energy efficiency.

\r\n

Is Your Outdoor HVAC Unit at Risk in the Rain?

\r\n

Your outdoor heat pump unit is really only susceptible to damage in flooding situations. If water starts to partially submerge the unit, the wiring, electronics, and motor could get damaged. The heat pump can work in the rain, but not in the water.

\r\n

If the outdoor unit is partially or fully submerged, turn off the HVAC system at the electrical panel. Have a professional inspect the system before turning it back on again.

\r\n

Other than extreme situations, your outdoor unit should be fine. It’s perfectly safe to run your heater or air conditioner while it’s raining or storming outside.

\r\n

Should You Cover the Outdoor Unit? 

\r\n

Since your condenser unit has been built to withstand moisture and extreme temperatures, it’s generally not a good idea to cover it. Some people choose to cover their units in the winter to protect it from rain, snow, leaves, and debris, but this can cause more harm than good.

\r\n

If moisture is allowed to evaporate, there’s no problem. Moisture may collect in the cover and the trapped condensation can lead to corrosion and other damage.

\r\n

Do NOT stack anything on top of the unit, especially when it’s running. It needs proper airflow to perform correctly. If you are worried about something falling down and damaging your unit, you may be able to build an awning-type shelter above the unit, but speak with a professional HVAC technician first.

\r\n

Can HVAC Technicians Service Units in the Rain?

\r\n

As a general rule, technicians do not service outdoor units in the rain. Besides the obvious danger of working on electrical components in the rain, moisture could cause damage to the unit. If the unit is on the roof, things are even more dangerous. Not only does the rain make everything slippery, but there may also be high winds and lightning.

\r\n

If the weather is bad enough, it’s just not safe for technicians to work on the outdoor unit. Sometimes, however, we will visit a home in bad weather in cases of an emergency. Always check first, but don’t be surprised if a technician has to wait for the weather to clear before servicing your unit, especially if it’s on the roof.

考虑到最近的降水,现在是时候回顾一下降雨对供暖和空调系统的影响了。bob国际娱乐

幸运的是,您的室外暖通空调机组的设计可以承受恶劣的天气条件,如雨,雪,甚至一点冰雹。不幸的是,如果天气条件恶劣,你可能不得不等待技术人员来维修你的HVAC机组,特别是如果它在屋顶上。

暖通空调设计

你的空调利用热泵技术将热量从室内泵到室外环境。室外机可以是空调或热泵既能加热又能冷却。

作为一个“分割系统”,一个单元位于内部(蒸发器线圈和鼓风机),另一个单元位于外部(压缩机和冷凝器)。

由于室外机暴露在元素中,所以它被建造成可以承受极端条件。这是通过密封电气元件,使用坚固的,耐腐蚀的材料,如铜,铝和塑料来实现的。

尽管采取了所有的预防措施,你的暖通空调系统仍然容易受到掉落的树枝、风吹的碎片、洪水和咸空气的破坏。

定期维护其中包括全面清洁,是避免昂贵维修和提高能源效率的最佳方式。

你的室外暖通空调在雨中有危险吗?

您的室外热泵机组实际上只在洪水情况下容易损坏。如果水开始部分淹没设备,接线、电子设备和电机可能会损坏。热泵可以在雨中工作,但不能在水中工作。

如果室外机部分或全部淹水,请关闭电气面板上的暖通系统。请专业人员检查系统后再重新开机。

除了极端情况,你的室外机应该没问题。在下雨或暴风雨的时候,打开暖气或空调是非常安全的。

你应该盖住室外机吗?

因为你的冷凝器可以承受潮气和极端温度,所以把它盖起来通常不是一个好主意。有些人选择在冬天盖住他们的单位,以保护它免受雨、雪、树叶和碎片的伤害,但这可能弊大于利。

如果允许水分蒸发,就没有问题。湿气可能会聚集在盖子内,冷凝物可能导致腐蚀和其他损坏。

不要将任何东西堆叠在设备顶部,特别是在运行时。它需要适当的气流才能正常工作。如果你担心有东西掉下来损坏你的房子,你可以在房子上面搭一个遮阳篷,但要先和专业的暖通空调技术人员谈谈。

暖通空调技术人员能在雨中为单位服务吗?

一般来说,技术人员不会在雨中维修室外设备。除了在雨中操作电气元件的明显危险外,湿气还可能对设备造成损坏。如果机组在屋顶上,情况就更危险了。雨水不仅会让一切变得很滑,而且还可能会有大风和闪电。

如果天气够坏,技术人员在户外设备上工作就不安全了。然而,有时,我们会在恶劣的天气下访问一个家庭,以应对紧急情况。一定要先检查,但如果技术人员必须等到天气放晴后才能维修你的设备,尤其是在屋顶上的设备,不要感到惊讶。
