10 Best Practices For AIR CONDITIONER
One of the most frustrating problems with a window air conditioner is if it starts to ice up. For who owns 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. обогреватель is the result of other difficulties.
It is most often the consequence of poor airflow.
Any time the airflow through an air conditioner is fixed the coolant system becomes affected. If taken 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 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 will appear as ice.
The primary job of an air conditioner is to de-humidify, not refrigerate, the room air. By detatching the moisture from the room air it gives us a feeling of comfort. To do this though the temperature of the cooling coil should always be higher than the room’s dew point. If it is 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 result in your air conditioning equipment 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 is effective) onto filter surface. Allow to sit for a few minutes. Add hot water to sink in order that filter is totally 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 will be best, but this could be costly unless you do-it-yourself. During cleaning the cooling coil should be degreased and washed to eliminate accumulated dirt and debris. Degreasing is important 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 can produce a lower airflow.
3. Dirty or blocked condenser coil.
The condenser coil is the one at the rear of the air conditioning equipment. 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. Because 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. If not cleaned regularly an airflow blockage here can even burn out the compressor. Before this happens although lowering of airflow will affect the entire 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 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 begin to refrigerate. Ice on the cooling coil will result. If the compressor itself reaches fault the air conditioner will have to 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 result in 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. Or even repaired recently then suspect airflow problems before considering a refrigerant imbalance.
6. Outdoor temperature too low.
Icing can occur if the outside 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 issue is more prevalent in the fall. If it’s hot during the day but cold at night suspect this problem because 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 room air without cooling it, while bringing in a small amount of outside air during the night.
