One of the very most frustrating problems with a window air conditioning equipment is if it starts to ice up. For the owner of the air conditioner is could be perplexing.
When this problem occurs a lot of people immediately believe that it is the fault of the refrigerant gas. More often the cause is the consequence of other difficulties.
It is most often the result of poor airflow.
Any time the airflow through an air conditioner is restricted the cooling system becomes affected. If taken to extremes the critical pressure-temperature balance of the cooling coil could be changed. Should they drop too low the cooling coils surface temperature can drop below the dew point temperature of the room. At these times the cooling coil will begin to operate as a refrigerator rather than an air conditioner. Instead of simply cooling the air it will collect and hold moisture. The moisture will freeze onto the cooling coil where it will appear as ice.
The principal job of an air conditioning equipment would be to de-humidify, not refrigerate, the area air. By detatching the moisture from the room air it gives us a sense of comfort. To do this though the temperature of the cooling coil should always be higher than the room’s dew point. If it’s permitted 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 result in your air conditioning equipment icing up:
1. Dirty filter.
In order to avoid this replace or clean your filter every little while of the cooling season. In case a smoker do it weekly. To completely clean filter remove from air conditioner, wet thoroughly, and lay in bottom of a sink. Sprinkle detergent (laundry detergent is effective) onto filter surface. Allow to sit for a couple of minutes. Add hot water to sink so that filter is completely covered. Soak for a 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 several years. Every year would be best, but this can be costly unless you do it yourself. During cleaning the cooling coil ought to be degreased and washed to remove accumulated dirt and debris. Degreasing is important to remove 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 will produce a lower airflow.
3. Dirty or blocked condenser coil.
інтернет-магазин обігрівачів may be the one at the rear of the air conditioner. Its job is to dissipate the heat that is being removed from the area. Just like the cooling coil it too should be cleaned every few years. Since the condenser is on the outside of the home it becomes exposed to lots of dirt, pollen, and smog. Since airflow direction is from inside to outside it is the inside surface of the condenser that becomes dirty. Therefore to clean this part the air conditioning equipment must be completely disassembled. Or even cleaned regularly an airflow blockage here can even burn up the compressor. Before this happens although lowering of airflow will affect the overall operation. This can result in 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 might not get cold enough to shut off the cold control. It can hover just above the cut off point. When this happens the cooling coil will quickly refrigerate. Ice on the cooling coil will result. If the compressor itself is at fault the air conditioner should be replaced. But remember that many icing problems are misdiagnosed as bad compressors when they were actually among the other faults discussed in the following paragraphs.
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 too much refrigerant. Blended with an airflow problem this is often difficult to diagnose. If not repaired recently then suspect airflow problems before considering a refrigerant imbalance.
6. Outdoor temperature too low.
Icing can occur if the exterior temperature falls below 60 Degrees Fahrenheit. If the outside temperature is too low the air conditioner pressure-temperatures can be affected. When the outside temperature falls the cooling coil temperature will also fall. So much that the coil will refrigerate the room air. This will bring about the cooling coil beginning to produce ice. This problem is more prevalent in the fall. If it is hot during the day but cold during the night suspect this problem because 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 will circulate the area air without cooling it, while attracting a small amount of outside air at night time.
