One of the most frustrating issues with a screen air conditioner is when it starts to ice up. For the owner of the air conditioner is may be perplexing.

Any time the airflow through an ac is restricted the cooling system becomes affected. If taken fully to extremes the critical pressure-temperature balance of the cooling coil may be changed. Should they drop too low the cooling coils surface temperature can drop below the dew point temperature of the area godrej 1 ton 3 star inverter split ac.When this happens the cooling coil will begin to operate as a fridge as opposed to an air conditioner. Rather than merely cooling the air it will collect and hold moisture. The moisture will freeze onto the cooling coil where it will be as ice.

The principal job of an ac would be to de-humidify, not refrigerate, the area air. By eliminating the moisture from the area air it gives us a feeling of comfort. To do this although temperature of the cooling coil must continually be higher than the room’s dew point. If it’s allowed to drop below the dew point the air conditioner will start to produce ice.

To avoid this replace or clean your filter every couple of weeks of the cooling season. In case a smoker do it every week. To completely clean filter remove from air conditioner, wet thoroughly, and lay in bottom of a sink. Sprinkle detergent (laundry detergent works well) onto filter surface. Allow to sit for some minutes. Add tepid to warm water to sink so that filter is completely covered. Soak for 15 minutes. Remove from water and rinse. Allow to air dry.

An ac requires regular maintenance. Usually every several years. Annually would be best, but this is costly until you do it yourself. During cleaning the cooling coil ought to be degreased and washed to eliminate accumulated dirt and debris. Degreasing is important to eliminate any coatings on the coil. If not done greasy residue can trap and hold air borne particles. They’ll build on the coil and affect heat transfer. If left too long this may result in the cooling coil becoming partially blocked. This can create a lower airflow.

The condenser coil is the one at a corner of the air conditioner. Its job would be to dissipate the warmth that’s being taken from the room. Just as the cooling coil it too must certanly be cleaned every few years. Because the condenser is on the outside of the home it becomes confronted with a lot of dirt, pollen, and smog. Since airflow direction is from inside to outside it is the interior surface of the condenser that becomes dirty. Therefore to completely clean this part the air conditioner must certanly be completely disassembled. If not cleaned regularly an airflow blockage here may also burn up the compressor. Before this happens although lowering of airflow will affect the entire operation. This may result in the compressor efficiency dropping, the interior pressure-temperature relationships being affected, and the resultant production of ice on the cooling coil.

As describe above an inefficient compressor may cause icing up. If the compressor is not able to pump the refrigerant properly the cooing coil may not get cold enough to shut off the cold control. It may hover just above the cut off point. When this happens the cooling coil will begin to refrigerate. Ice on the cooling coil will result. If the compressor itself is responsible the air conditioner must be replaced. But note that many icing issues are misdiagnosed as bad compressors when they certainly were actually among the other faults discussed in this article.

Both scenarios may result in and icing condition. If your air conditioner was repaired recently suspect an excessive amount of refrigerant. Combined with an airflow problem this is difficult to diagnose. If not repaired recently then suspect airflow problems before considering a refrigerant imbalance.

Icing can occur if the surface temperature falls below 60 Degrees Fahrenheit. If the surface temperature is too low the air conditioner pressure-temperatures may be affected. When the surface temperature falls the cooling coil temperature may also fall. So much that the coil will refrigerate the area air. This can lead to the cooling coil beginning to produce ice. This issue is more prevalent in the fall. If it’s hot through the day but cold at night suspect this issue as the cause of icing up. If this issue is suspected try running the air conditioner in the fan only position. Leave the re-circulating vent open. This can circulate the area air without cooling it, while bringing in a little bit of outside air during the night.
