Why You Never See AIR CONDITIONER That Actually Works

One of the very most frustrating problems with a window air conditioner is if it starts to ice up. For who owns the air conditioner is could be perplexing.

When this problem occurs a lot of people immediately think 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 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 can 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 instead of 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 primary job of an air conditioner would be to de-humidify, not refrigerate, the room air. By removing the moisture from the room air it gives us a sense of comfort. To get this done although 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 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 every week. 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 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 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 eliminate 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’ll 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 at the rear of the air conditioner. Its job would be to dissipate the heat that is being removed from the area. Just like the cooling coil it too must be cleaned every few years. Since the condenser is externally of the home it becomes exposed to plenty of 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 空氣淨化機推薦 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 off the cold control. It could hover just above the cut 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 when they were actually one of the other faults discussed in this article.

5. Not enough refrigerant. Too much refrigerant.
Both scenarios can result in and icing condition. If your air conditioning equipment was repaired recently suspect too much 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 outside temperature falls below 60 Degrees Fahrenheit. If the outside temperature is too low the air conditioning equipment 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 area air. This will bring about the cooling coil starting to produce ice. This issue is more frequent in the fall. If it’s hot throughout the day but cold during the night suspect this problem because the reason behind icing up. If this problem is suspected try running the air conditioner in the fan only position. Leave the re-circulating vent open. This will circulate the room air without cooling it, while attracting handful of outside air at night time.
