移机后出现制冷效果差该如何排查：
How to check the poor refrigeration effect after moving the machine:
1、首先检查外机上的铜螺丝帽是否有水珠，如果有水珠，就证明空调内还有缺氟缺氨；如果没水珠，可进一步检查空调外机是否有东西阻挡，比如防盗网、铁栅栏都会影响空调散热效果。
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、排除以上原因的话，可查看空调外机散热板是否有积尘。
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、内机如果长期未清洗，也会影响制冷效果。而线路老化或负荷过大等原因造成的电压不稳也会导致空调制冷效果不好。
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、房间过大，空调马力不足，会造成人感觉空调不制冷。
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、空调安装不合理，通风管过长，热传递效率低也会造成不制冷。
5. Unreasonable installation of air conditioner, too long ventilation pipe and low heat transfer efficiency will also lead to non refrigeration.
6、室外温度超过43度时，大多数空调难以把室内热量传递给室外，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.
