How to repair and maintain the central air conditioning frost

With the arrival of the hot summer, more and more families will open the central air conditioning, many users find that when using the central air conditioning, there is condensation at the outlet, and sometimes it will drip down, wetting the ground, this situation is some common central air conditioning so what is the reason for the central air conditioning frost?

First, the central air conditioning frost reasons

1, the central air conditioning tuyere area of the air humidity is large;

2. Due to the unreasonable setting of the new exhaust system in the central air conditioning area, excessive negative pressure occurs, which makes the unarranged outdoor air enter the room, and then increases the humidity of the air and its condensation dew point;

3, the central air conditioner itself uses a large temperature difference to supply air, and the machine itself is not equipped with air supply and cold volume, resulting in too much cold volume and too little air volume;

4, central air conditioning tuyere, air supply outlet use aluminum material, due to good thermal conductivity, making the surface temperature of tuyere data is too low and condensation dew;

Second, the central air conditioning frost maintenance methods

1, as far as possible to reduce the number of doors open, check whether the indoor and the outside world is not sealed;

2, increase the central air conditioning air supply volume, as far as possible to adjust the wind speed to high or open the regulating valve as far as possible;

3, if the central air conditioning tuyere for the side of the wind, the transverse louver as far as possible to blow out, to prevent the louver after condensation to the outflow;

4, if conditions, you can stick a thin PE insulation board at the end of the central air conditioning tuyere;

5, choose (ABS) plastic tuyere;

6, appropriate improvement of air supply temperature.
