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 can be perplexing.
When интернет магазин интер-климат occurs most people immediately believe that it is the fault of the refrigerant gas. More regularly the cause is the result of other difficulties.
It is most often the consequence of poor airflow.
Any time the airflow through an air conditioner is restricted the cooling system becomes affected. If taken up to extremes the critical pressure-temperature balance of the cooling coil can be changed. If they drop too low the cooling coils surface temperature can drop below the dew point temperature of the room. When this happens 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’ll appear as ice.
The principal job of an air conditioning equipment is to de-humidify, not refrigerate, the area air. By removing the moisture from the area 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 permitted to drop below the dew point the air conditioner will begin to produce ice.
With this information at heart the following are several problems that can result in your air conditioner icing up:
1. Dirty filter.
To avoid this replace or clean your filter every little while 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 is effective) onto filter surface. Allow to sit for a couple of minutes. Add warm water to sink in order that filter is completely covered. Soak for 15 minutes. Remove from water and rinse. Allow to air dry.
2. Dirty or blocked cooling coil.
An air conditioner requires regular maintenance. Usually every several years. Every year would be best, but this could 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 essential to remove any coatings on the coil. If not done greasy residue can trap and hold air borne particles. They will build up on the coil and affect heat transfer. If left too long this can result in the cooling coil becoming partially blocked. This will 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 externally of the home it becomes exposed to many 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 out the compressor. Before this happens though the lowering of airflow will affect the entire operation. This can bring about the compressor efficiency dropping, the internal 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 is not able to pump the refrigerant properly the cooing coil might not get cold enough to shut down the cold control. It can 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 should be replaced. But note that many icing problems are misdiagnosed as bad compressors if they were actually among the other faults discussed in this post.
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 is often 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 the exterior temperature falls below 60 Degrees Fahrenheit. If the exterior temperature is too low the air conditioner pressure-temperatures can be affected. Once the outside temperature falls the cooling coil temperature will also fall. So much that the coil will refrigerate the area air. This will result in the cooling coil beginning to produce ice. This problem is more frequent 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 will circulate the area air without cooling it, while bringing in handful of outside air during the night.
