Why is air conditioning not cooling?

In the hot summer, the most comfortable thing is to eat a cold watermelon while eating ice watermelon. However, this kind of comfortable enjoyment is sometimes difficult to achieve because the air conditioner is not cooled. Recently, Mr. Li, who lives in Houkou, Hankou, is faced with such a problem. When the temperature rises at 32 °C and 34 °C, the air conditioner of his own home is always weak. The socket is replaced and the remote control battery is still not cooled. Then, why is the air conditioner not cooling in summer, and what causes the air conditioner not to cool? Let's take a look at the introduction of the comfort 100 network expert.

 

1. The indoor area is too large and the cooling capacity of the air conditioner is too small. It is like a bull-drawn cart, a small power or an old air conditioner that delivers cold air to a large room. The cooling effect is of course not obvious. There is also a poor indoor airtightness, or an increase in heat sources ( such as computers, rice cookers, etc. ) , which will also cause the cooling effect of the air conditioner to decrease, causing the user to have the illusion that the cooling effect is reduced.

 

2. The outdoor unit is easy to absorb dust and debris due to exposure. If it is not cleaned for a long time, it will affect the heat dissipation performance of the machine and reduce the cooling effect of the air conditioner. In addition, the filter network has too much ash, which blocks the air circulation, and also causes the internal cooling capacity of the machine to be brought out by the flowing air in time, resulting in insufficient cooling capacity.

 

3. The power supply voltage is too low, causing the air conditioner to be difficult to start, stop after starting, or the fuse is blown. This is not a fault. As long as the power supply is checked, the voltage of the grid is too low. The user should install a power regulator to make the voltage reach 220V , so that the air conditioner can be used normally.

 

4 , the problem of the compressor, the use of the time is too long, the compressor is aging, the effect is not enough before, like the sound of air conditioning, the vibration is relatively large, you need to consider whether the compressor problem, such problems can only find professionals to maintain, Or consider buying a new machine.

 

5 , lack of snow species ( Freon ) , the lack of snow for air conditioning is a normal situation, this is usually the case with old air conditioners used for 3-4 years. Old-fashioned air conditioners use Freon as a refrigerant, and the refrigerant will volatilize. If the air conditioner is improperly installed, it will cause snow leakage. When the summer temperature is 33 degrees, the indoor temperature is about 28 degrees. When you find the thin tube frosting from the outdoor unit, or if there is more dripping than usual, you can explain the lack of air conditioning and lack of snow.

 

6. The copper tube between the indoor and outdoor units of the air conditioner is too long. When installing the air conditioner, if the distance of the outdoor unit is too far to reduce the noise, the air duct is too long and the transmission distance is too far, so that the cooling effect of the air conditioner is greatly reduced. This also reminds us to find an experienced professional company when installing air conditioners.
