When this issue happens many people promptly assume it is the mistake of the refrigerant gas. More frequently the reason is the outcome of other problems. It is most often the outcome of poor airflow. Any time the airflow via an air conditioning unit is limited the cooling system comes to be affected. If required to extremes the essential pressure-temperature balance of the air conditioning coil can be transformed. If they drop as well low the air conditioning coils surface area temperature can go down listed below the dew point temperature of the room.

When this takes place the cooling coil will certainly begin to operate as a fridge instead of an 冷氣機. As opposed to simply cooling the air it will gather and also hold wetness. The wetness will certainly ice up onto the cooling coil where it will certainly appear as ice. The key work of an air conditioning unit is to de-humidify, not cool, the area air. By removing the moisture from the room air it provides us a feeling of convenience. To do this though the temperature level of the cooling coil must constantly be greater than the space’s humidity.

During cleansing the air conditioning coil should be degreased as well as cleaned to eliminate gathered dirt and debris. Degreasing is essential to eliminate any type of finishes on the coil. Otherwise done oily deposit can catch as well as hold air borne particles. They will develop on the coil and also impact heat transfer. If left also long this can result in the air conditioning coil becoming partially blocked. This will certainly create a reduced air movement.
