One of the most frustrating issues with a window air conditioning equipment is if it starts to ice up. For the owner of the air conditioner is can be perplexing.
When this problem occurs a lot of people immediately think it is the fault of the refrigerant gas. More regularly the cause is the result of other difficulties.
It is most often the result of poor airflow.
Any time the airflow via an air conditioner is fixed the coolant system becomes affected. If taken up to extremes the critical pressure-temperature balance of the cooling coil could be changed. If they drop too low the cooling coils surface temperature can drop below the dew point temperature of the area. When this happens the cooling coil will quickly operate as a refrigerator instead of an air conditioner. Instead of simply cooling the air it’ll collect and hold moisture. The moisture will freeze onto the cooling coil where it’ll appear as ice.
The principal job of an air conditioner would be to de-humidify, not refrigerate, the room air. By removing the moisture from the room air it gives us a feeling of comfort. To get this done although temperature of the cooling coil should always be greater than the room’s dew point. If it’s allowed to drop below the dew point the air conditioner will start to produce ice.
With this information at heart the following are a few problems that can lead to your air conditioner icing up:
1. Dirty filter.
In order to avoid this replace or clean your filter every couple of weeks of the cooling season. If a smoker do it weekly. To completely clean filter remove from air conditioning equipment, wet thoroughly, and lay in bottom of a sink. Sprinkle detergent (laundry detergent works well) onto filter surface. Allow to sit for a couple of minutes. Add hot water to sink so that filter is totally covered. Soak for quarter-hour. Remove from water and rinse. Allow to air dry.
2. Dirty or blocked cooling coil.
An air conditioning equipment requires regular maintenance. Usually every two or three years. Every year would be best, but this can be costly unless you do it yourself. During cleaning the cooling coil should be degreased and washed to remove accumulated dirt and debris. Degreasing is important to eliminate any coatings on the coil. Or even done greasy residue can trap and hold air borne particles. They’ll build-up on the coil and affect heat transfer. If left too much time this can bring about the cooling coil becoming partially blocked. This can produce a lower airflow.
3. Dirty or blocked condenser coil.
The condenser coil is the one guiding the air conditioning equipment. Its job would be to dissipate the heat that is being removed from the room. Similar to the cooling coil it too should be cleaned every few years. Since the condenser is on the outside of the house it becomes exposed to lots of dirt, pollen, and smog. Since airflow direction is from inside to outside it’s the inside surface of the condenser that becomes dirty. Therefore to clean this part the air conditioner must be completely disassembled. If not cleaned regularly an airflow blockage here may also burn out the compressor. Before this happens though the lowering of airflow will affect the overall operation. This can bring about the compressor efficiency dropping, the inner pressure-temperature relationships being affected, and the resultant production of ice on the cooling coil.
4. Inefficient compressor.
As describe above an inefficient compressor can cause icing up. If the compressor struggles to pump the refrigerant properly the cooing coil may not get cold enough to shut down the cold control. It could hover just above the take off point. At these times the cooling coil will quickly refrigerate. Ice on the cooling coil will result. If the compressor itself reaches fault the air conditioner will have to be replaced. But remember that many icing problems are misdiagnosed as bad compressors if they were actually one of the other faults discussed in this posting.
5. Not enough refrigerant. An excessive amount of refrigerant.
Both scenarios can lead to and icing condition. If your air conditioner was repaired recently suspect an excessive amount of refrigerant. Blended with an airflow problem this can be difficult to diagnose. Or even repaired recently then suspect airflow problems before considering a refrigerant imbalance.
6. Outdoor temperature too low.
Icing can occur if купить обогреватель в Днепре falls below 60 Degrees Fahrenheit. If the outside temperature is too low the air conditioning equipment pressure-temperatures can be affected. When the outside temperature falls the cooling coil temperature may also fall. So much that the coil will refrigerate the area air. This will bring about the cooling coil beginning to produce ice. This issue is more prevalent in the fall. If it is hot throughout the day but cold at night suspect this problem as the reason behind icing up. If this problem is suspected try running the air conditioning equipment in the fan only position. Leave the re-circulating vent open. This can circulate the area air without cooling it, while attracting a small amount of outside air during the night.
