One of the most frustrating problems with a window ac is if it starts to ice up. For the master of the ac is could be perplexing.
Any moment the airflow through an air conditioner is restricted the cooling 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 godrej 1 ton 3 star inverter split ac.When this occurs the cooling coil will start to operate as a fridge as opposed to an air conditioner. Rather than cooling the air it will collect and hold moisture. The moisture will freeze onto the cooling coil where it can look as ice.
The principal job of an air conditioner is always to de-humidify, not refrigerate, the room air. By eliminating the moisture from the room air it provides us a feeling of comfort. To do this although the temperature of the cooling coil must continually be higher compared to room’s dew point. When it is permitted to drop below the dew point the ac will begin to produce ice.
To prevent this replace or clean your filter every number of weeks of the cooling season. If a smoker do it every week. To clean filter remove from ac, wet thoroughly, and lay in bottom of a sink. Sprinkle detergent (laundry detergent works well) onto filter surface. Allow to sit for some 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.
An air conditioning equipment requires regular maintenance. Usually every several years. Annually will be best, but this is costly unless you do it yourself. During cleaning the cooling coil must certanly be degreased and washed to get rid of accumulated dirt and debris. Degreasing is very important to get rid of 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 may result in the cooling coil becoming partially blocked. This will make a lower airflow.
The condenser coil is the one at a corner of the air conditioner. Its job is always to dissipate the heat that is being taken off the room. Just like the cooling coil it too must certanly be cleaned every few years. Since the condenser is on the exterior of the house it becomes subjected 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 completely clean this part the ac must certanly be completely disassembled. If not cleaned regularly an airflow blockage here will even burn out the compressor. Before this happens although the lowering of airflow will affect the general operation. This may result in the compressor efficiency dropping, the inner pressure-temperature relationships being affected, and the resultant production of ice on the cooling coil.
As describe above an inefficient compressor may cause icing up. If the compressor is incapable of pump the refrigerant properly the cooing coil might not get cold enough to shut off the cold control. It may hover just above the cut off point. When this occurs the cooling coil will start to refrigerate. Ice on the cooling coil will result. If the compressor itself is to blame the ac will have to be replaced. But note that numerous icing issues are misdiagnosed as bad compressors when these were actually one of many other faults discussed in this article.
Both scenarios may result in and icing condition. If your ac was repaired recently suspect an excessive amount of refrigerant. Mixed with an airflow problem this is difficult to diagnose. If not repaired recently then suspect airflow problems before considering a refrigerant imbalance.
Icing can occur if the surface temperature falls below 60 Degrees Fahrenheit. If the surface temperature is too low the ac pressure-temperatures could be affected. When the surface temperature falls the cooling coil temperature will also fall. So much that the coil will refrigerate the room air. This can lead to the cooling coil beginning to create ice. This problem is more prevalent in the fall. When it is hot throughout the day but cold during the night suspect this dilemma as the reason for icing up. If this dilemma is suspected try running the ac in the fan only position. Leave the re-circulating vent open. This will circulate the room air without cooling it, while bringing in a small amount of outside air during the night.
