Turn Your AIR CONDITIONER Into A High Performing Machine
One of the most frustrating problems with a window air conditioning equipment is if it starts to ice up. For who owns the air conditioner is could be perplexing.
When this problem occurs most people immediately believe that it is the fault of the refrigerant gas. More often the cause is the result of other difficulties.
It is most often the result 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 could be changed. Should they drop too low the cooling coils surface temperature can drop below the dew point temperature of the area. At these times the cooling coil will quickly operate as a refrigerator rather than an air conditioner. Rather than 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 area air it gives us a sense of comfort. To get this done although temperature of the cooling coil must 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 in mind the following are several problems that can lead to 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 conditioner, 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 so 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 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 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 much time 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 conditioner. Its job is to dissipate the heat that is being removed from the area. Similar to the cooling coil it too must be cleaned every few years. Because the condenser is externally 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 completely 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 although lowering of airflow will affect the overall operation. This can result in 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 интернет-центр климатической техники is not able to pump the refrigerant properly the cooing coil may not get cold enough to shut off the cold control. It could 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 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 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 conditioning equipment was repaired recently suspect an excessive amount of 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 outside temperature falls below 60 Degrees Fahrenheit. If the outside temperature is too low the air conditioning equipment pressure-temperatures can be affected. Once the outside temperature falls the cooling coil temperature may 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 is hot throughout the day but cold during the night suspect this problem because the cause of 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 room air without cooling it, while attracting a small amount of outside air at night time.
