Determine whether it is necessary to refuel the air conditioner at home, its owner may well be on his own. Special knowledge and equipment for this are not required. There are two main signs that Freon in the system is not enough. About them, and also about, how to charge the air conditioner at home, read on.
Causes of Freon Leaks
-
Pressure meterPoor pipe connections. All connections freonotrassy produced by rolling. If technology was broken during the fastening process, leaks are inevitable. They will become noticeable in just a few months of operation of the equipment, since with a shortage of 15 - 18% of the refrigerant, the cooling efficiency decreases markedly. Therefore, the work is carried out not according to the norms of filling the air conditioner, but according to the condition of the equipment;
- Natural evaporation. Often, no matter how tight the tubes are connected, freon evaporates in an amount of 5 - 8% per year.
Particularly careful should be the owners who have saved on installation. If it was conducted by a lone handicraftsman, rather than a master from a specialized company, the likelihood of poor-quality connections is significantly increased.
So, to understand: is it necessary to refuel an air conditioner, any user of climatic equipment can.
When to refuel an air conditioner?
How often do I need to refuel an air conditioner? As soon as the homeowner discovers the following symptoms, individually or in combination:
- Air conditioning blows but does not cool. Less refrigerant carries less cold. Therefore, the effect of the system is reduced;
- At the pipe joints and fittings, ice freezes, frost. In especially severe cases, the outdoor unit is also covered with hoarfrost. This is explained by the fact that to compress a small amount of refrigerant, the compressor has to work with increased load. By the way, it wears out faster. And this is the main danger of a lack of refrigerant in the system;
- After reinstallation. In the process of dismantling, part of the refrigerant necessarily evaporates. Therefore, it is necessary to automatically charge the air conditioner when it is installed in a new place;
- After repair of the outdoor unit. The air conditioner must be charged when there is a possibility of abundant evaporation of the refrigerant. In some cases, it is necessary to completely drain the freon for repair.
Air conditioner refueling rates
Automatic refueling of air conditioners is possible, unfortunately, only for automotive climatic equipment, but not for home. Refueling of household and industrial systems is carried out under the control of pressure gauges, scales or visually.
Norms for refueling air conditioners do not exist.
Add refrigerant as much as it evaporated or leaked. If the equipment is refueling from scratch, the instructions contain recommendations for operating pressure. They are guided by them when it is necessary to refuel the air conditioner.
