Air conditioning refrigeration is normal, but the room temperature just can't come down. Why?

The air conditioning refrigeration effect is not good, or the room is not well sealed and insulated.

When the air conditioner works for about half an hour, measure the temperature difference between the inlet and outlet of the indoor unit with a thermometer. If the temperature difference is about 12 degrees, it shows that the air conditioning has good refrigeration performance, which is mostly caused by poor sealing and heat preservation conditions of the room. If the temperature is too low, it means that the air conditioning refrigeration effect is not good, so you should contact the seller in time or return or repair after sale.

1.5 air conditioning refrigeration capacity of 3500W is suitable for rooms around 18 square meters. Room 14 square meter can be equipped with 1.2 air conditioner, with a cooling capacity of 3200W W, and the cooling effect of 1.5 air conditioner is poor. If the room is well sealed and insulated, there must be something wrong with the air conditioner, or the power supply voltage is unstable or too low.

Precautions for use:

1, the power supply voltage should not fluctuate too much (10% fluctuation is allowed), the air conditioner should be powered by a dedicated line, and the single-phase three hole socket should be used, and the plug should be plugged to the end.

2. The casing of the indoor unit should be cleaned frequently. Generally, it can be wiped clean with a clean dry cloth or neutral detergent. It is absolutely not allowed to rinse directly with water. If it is wiped with a cloth, it should be done after the power is cut off.

3. The indoor temperature should not be adjusted too low, otherwise it will be harmful to human body, and the set temperature should be adjusted appropriately.
