Why Most People Will Never Be Great At AIR CONDITIONER

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

แอร์บ้านราคาถูก When this problem 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 result of poor airflow.

Any time the airflow via an air conditioner is fixed the coolant system becomes affected. If taken up 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 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 would be 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 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 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.
In order to avoid this replace or clean your filter every couple of weeks 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 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 conditioning equipment requires regular maintenance. Usually every two or three years. Every year will 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 eliminate any coatings on the coil. Or even done greasy residue can trap and hold air borne particles. They’ll 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 at the rear of the air conditioning equipment. Its job is to dissipate the heat that’s being removed from the area. Similar to the cooling coil it too should be cleaned every few years. Because the condenser is on the outside of the house 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 completely clean this part the air conditioner must be completely disassembled. Or even cleaned regularly an airflow blockage here may also burn up the compressor. Before this happens although lowering of airflow will affect the overall 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 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 take off point. At these times the cooling coil will quickly refrigerate. Ice on the cooling coil will result. If the compressor itself is at fault the air conditioner should be replaced. But remember that many icing problems are misdiagnosed as bad compressors if they were actually among the other faults discussed in this posting.

5. Not enough refrigerant. Too much refrigerant.
Both scenarios can result in and icing condition. If your air conditioning equipment 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 outside 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 will also fall. So much that the coil will refrigerate the room 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 as the cause of icing up. If this problem is suspected try running the air conditioner 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.
