Air conditioner gas recharging is a technical process to restore the efficiency of air conditioners that have lost their cooling performance or are not working at all.<\/p>\n\n\n\n

In many systems, from domestic split air conditioners to commercial systems and even vehicle air conditioners, it is necessary to refill the refrigerant gas that decreases or decreases over time.<\/p>\n\n\n\n

In this article, you will find every detail, from the process of pumping gas into the air conditioner, the types of gas used, gas calculation according to BTU and safety warnings.<\/p>\n\n\n\n

What is Air Conditioner Gas Charging?<\/h2>\n\n\n\n

Air conditioner gas recharging is the process of refilling the refrigerant (gas) circulating in the system in case of a shortage. This gas is the main component that provides the air cooling cycle of the air conditioning system. When the gas is missing, the air conditioner cannot function properly, it will not cool and the compressor may even be damaged.<\/p>\n\n\n\n

How Do We Know When the Air Conditioner is Out of Gas?<\/h2>\n\n\n\n

The air conditioner may need to be gassed in the following cases: <\/h3>\n\n\n\n

Signs Indicating Lack of Gas<\/p>\n\n\n\n

Air conditioning works but does not cool<\/p>\n\n\n\n

Blowing air is hot or normal<\/p>\n\n\n\n

Icing of indoor unit pipes<\/p>\n\n\n\n

Hissing sound coming from the outdoor unit<\/p>\n\n\n\n

Compressor runs continuously but no efficiency<\/p>\n\n\n\n

Types of Gas Used and Their Properties<\/p>\n\n\n\n

R22 Gas<\/h3>\n\n\n\n

Common in legacy systems<\/p>\n\n\n\n

Not used in new systems<\/p>\n\n\n\n

R410A Gas<\/h3>\n\n\n\n

Common in new generation split air conditioners<\/p>\n\n\n\n

More environmentally friendly and efficient<\/p>\n\n\n\n

Works with high pressure, requires special manifold<\/p>\n\n\n\n

R32 Gas<\/h3>\n\n\n\n

The most up-to-date and environmentally friendly gas type<\/p>\n\n\n\n

These quantities are based on standard piping lengths. Approximately +20-30 g of gas may be required for each additional meter.<\/p>\n\n\n\n

How to Calculate Gas for Split Air Conditioners?<\/h2>\n\n\n\n

The gas calculation is based on the air conditioner capacity (BTU), the pipe length and the type of gas used.<\/p>\n\n\n\n

Connection Pipe Configuration<\/p>\n\n\n\n

Standard length of connection pipe – 5m~ 7.5m~ 8m<\/p>\n\n\n\n

Minimum length of the connection pipe:<\/p>\n\n\n\n

For units with a standard connection pipe of 5m, there is no limit to the minimum length of the connection pipe. For units with 7.5 m and 8 m standard connection pipe, the minimum length of the connection pipe is 3m.<\/p>\n\n\n\n

Method for calculating the amount of additional A\/C gas oil and A\/C gas refill<\/p>\n\n\n\n

after extending the connecting pipe;<\/p>\n\n\n\n

After extending the connecting pipe length by 10m compared with the standard length, you need to add 5ml of A\/C gas oil for every additional 5m of the connecting<\/p>\n\n\n\n

pipe.<\/p>\n\n\n\n

How to calculate the additional A\/C gas filling amount (based on the liquid pipe):<\/p>\n\n\n\n

Additional A\/C gas refill amount = extended length of liquid pipe x additional<\/p>\n\n\n\n

How to Calculate Gas in VRF Air Conditioners?<\/h2>\n\n\n\n

In order to charge additional gas to Vrf Air Conditioning systems, the total liquid line of the copper pipes drawn in the system is collected. Each pipe diameter has a (kg\/m) value. Pipe diameters are multiplied by these values separately and summed.<\/p>\n\n\n\n

Additional Gas Charge Calculation Table<\/h3>\n\n\n\n

3\/4<\/td>0,25<\/td><\/tr>
7\/8<\/td>0,35<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

For example, 150 meters of liquid line was drawn in a Vrf Air Conditioning system. 50 meters of 1\/4, 50 meters of 3\/8, 50 meters of 1\/2<\/p>\n\n\n\n

50×0,022= 1,1<\/p>\n\n\n\n

50×0,054= 2,7<\/p>\n\n\n\n

50×0,11 = 5,5<\/p>\n\n\n\n

5,5+2,7+1,1= 9,3 The amount of gas to be added to the system is 9,3 kg.<\/p>\n\n\n\n

If the outdoor unit does not have gas, it is added to this calculation according to the label value on it.<\/p>\n\n\n\n

How is Air Conditioner Gas Charging Done?<\/h2>\n\n\n\n

Step-by-Step Air Conditioner Gas Refill Process<\/h3>\n\n\n\n
    \n
  • 1. The outdoor unit covers are opened and the manifold set is connected<\/li>\n\n\n\n
  • 2. Vacuuming is done (air and moisture are drawn out)<\/li>\n\n\n\n
  • 3. The required amount of gas is weighed and printed with a precision balance<\/li>\n\n\n\n
  • 4. Leakage control is performed<\/li>\n\n\n\n
  • 5. The device is started and tested.<\/li>\n<\/ul>\n\n\n\n
