Take 10 Minutes to Get Started With AIR CONDITIONER

One of the 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 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 via an air conditioner is restricted 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 room. At 冷氣機雪種價錢 cooling coil will begin to operate as a refrigerator rather than an air conditioner. Rather than 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 conditioner is to de-humidify, not refrigerate, the area air. By detatching the moisture from the area air it gives us a sense of comfort. To do this though the 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 conditioning equipment will begin to produce ice.

With this information at heart the following are a few problems that can lead to your air conditioning equipment icing up:

1. Dirty filter.
To avoid this replace or clean your filter every little while of the cooling season. In case a smoker do it weekly. To 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 tepid to warm 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 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 eliminate any coatings on the coil. Or even 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 bring about 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 is to dissipate the heat that is being removed from the area. Similar to the cooling coil it too should be cleaned every few years. Because the condenser is externally of the house it becomes exposed to many 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 conditioning equipment 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 could 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 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 note that many icing problems are misdiagnosed as bad compressors when 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. Mixed with an airflow problem this could be 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 exterior 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 problem is more prevalent in the fall. If it’s hot during the day but cold during the night suspect this problem as the reason behind icing up. If this issue 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 attracting handful of outside air during the night.
