How To Start A Business With AIR CONDITIONER

One of the very most frustrating problems with a window air conditioner is if it starts to ice up. For the owner of 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 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 can be changed. If they drop too low the cooling coils surface temperature can drop below the dew point temperature of the area. When this happens the cooling coil will quickly 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 will appear as ice.

The principal job of an air conditioning equipment would be to de-humidify, not refrigerate, the room air. By detatching the moisture from the area air it gives us a sense of comfort. To do this although temperature of the cooling coil must always be greater than the room’s dew point. If it’s permitted to drop below the dew point the air conditioning equipment will start to produce ice.

With this information in mind the following are several problems that can result in your air conditioning equipment icing up:

1. Dirty filter.
To avoid интер-климат or clean your filter every couple of weeks of the cooling season. If a smoker do it every week. 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 couple of minutes. Add hot water to sink so that filter is totally covered. Soak for quarter-hour. 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 will be best, but this is often costly unless you do-it-yourself. During cleaning the cooling coil should 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 may be the one at the rear of the air conditioner. Its job would be to dissipate the heat that is being removed from the room. Similar to the cooling coil it too should be cleaned every few years. Since the condenser is on the outside of the home it becomes exposed to lots 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 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 though the lowering of airflow will affect the overall operation. This can result in 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 may not get cold enough to shut down the cold control. It could 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 remember that many icing problems are misdiagnosed as bad compressors when they were actually among the other faults discussed in the following paragraphs.

5. Not enough refrigerant. Too much refrigerant.
Both scenarios can lead to and icing condition. If your air conditioning equipment was repaired recently suspect an excessive amount of refrigerant. Mixed with an airflow problem this can 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 may also fall. So much that the coil will refrigerate the area air. This will result in the cooling coil starting 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 as 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 can circulate the room air without cooling it, while attracting handful of outside air at night time.
