移機后出現制冷效果差該如何排查
移機后出現制冷效果差該如何排查：
How to check the poor refrigeration effect after moving the machine:
1、首先檢查外機上的銅螺絲帽是否有水珠，如果有水珠，就證明空調內還有缺氟缺氨；如果沒水珠，可進一步檢查空調外機是否有東西阻擋，比如防盜網、鐵柵欄都會影響空調散熱效果。
1. First, check whether there are water drops on the copper screw cap on
the external machine. If there are water drops, it proves that there is
a lack of fluorine and ammonia in the air conditioner; If there is no
water drop, you can further check whether there is something blocking
the external unit of the air conditioner, such as anti-theft net and
iron fence, which will affect the heat dissipation effect of the air
conditioner.
2、排除以上原因的話，可查看空調外機散熱板是否有積塵。
2. If the above reasons are eliminated, check whether there is dust on
the cooling plate of the external unit of the air conditioner.
3、內機如果長期未清洗，也會影響制冷效果。而線路老化或負荷過大等原因造成的電壓不穩也會導致空調制冷效果不好。
3. If the internal machine is not cleaned for a long time, it will also
affect the refrigeration effect. The unstable voltage caused by aging
lines or excessive load will also lead to poor refrigeration effect of
air conditioning.
4、房間過大，空調馬力不足，會造成人感覺空調不制冷。
4. If the room is too large and the horsepower of the air conditioner is
insufficient, adults will feel that the air conditioner does not cool.
5、空調安裝不合理，通風管過長，熱傳遞效率低也會造成不制冷。
5. Unreasonable installation of air conditioner, too long ventilation
pipe and low heat transfer efficiency will also lead to non
refrigeration.
6、室外溫度超過43度時，大多數空調難以把室內熱量傳遞給室外，造成不制冷。
6. When the outdoor temperature exceeds 43 ℃, most air conditioners are
difficult to transfer indoor heat to the outside, resulting in non
refrigeration.
