How to fill the air conditioner?

Any air conditioner works on freon, which eventually ends. After that, the air conditioner starts to warm up and does not work properly. This is a sure sign that it's time to refuel the air conditioner.

Be able to refuel the air conditioner yourself - a thingnecessary. However, self-priming the air conditioner is not so simple. This can lead to breakdown and then the technician will need to take to the service, where they will take even more money.

On how to refill the air conditioner yourself, read below.

How to properly fill the air conditioner

Before you start refueling the air conditioner,You need to buy freon, which operates your air conditioner. Freon is a safe gas and is sold in many stores. You also need to know the amount you need. This can be found in the instructions for the air conditioner.

After that, take all the necessary tools.

What tools are needed to refill the air conditioner

You will need:

• Thermometer for measuring air temperature.
• Refueling time clock.
• Vacuum pump to create a vacuum in the cylinder of the air conditioner.
• Manometric station.
• Instruction from the air conditioner.

Having these tools, you can start refueling with freon air conditioner.

How to refuel an air conditioner

Before refueling, you need to determine the performance of the air conditioner. For this it is sufficient:

1. Find the outer tube of the air conditioner and insert a manometer there.
2. Measure the pressure.
3. In passing, measure the temperature of the thermometer.

If the outside temperature is 23 degrees and above, and the air conditioner works on

normal power, then the manometer should show 4-5 bars. All normal readings should be recorded in the table in the air conditioner documentation.

Connect the Freon bottle to the valve,which is located on a special tube connected to the air conditioner. See the location of the tube can be in the instructions to the air conditioner. The procedure is safe and does not require special skills.

Discontinue refueling with freon,as the temperature on the thermometer, brought to the airflow of the air conditioner, will begin to rise sharply. This will mean that the capacity of the air conditioner is full. After completion of filling, the temperature is normalized according to the data in the table in the manual.

There are several ways to refuel the air conditioner by its parameters.

Refilling the air conditioner using the manufacturer's pressure table

The injection of freon occurs through the manometric collector in small portions.

After each small dose, it is necessary to measurepressure gauge and compare the indicators with the manufacturer's table. When the pressure values ​​align with the norm in the table, stop the injection of Freon.

This method requires a lot of time and good skills. It is best to let the specialist do it.

Refilling the air conditioner by weight

The method involves weighing the refrigerant cylinderand monitoring the weight of the balloon during the injection of Freon into the air conditioner. To measure the weight of the balloon it is possible to use special scales which will show the exact value of the gas left into the air conditioner. Such watches are often sold in construction stores.

But there is one difficulty - before starting filling it is necessary to pump freon out of the air conditioner and conduct a vacuum process with a pump, which can not always be done quickly.

Also it is necessary to know exactly the required volume of gas for the air conditioner in order to properly fill it.

Refrigerant conditioning refrigeration

In this method, measure the temperature and look at its difference. Proceeding from this, and spend

refueling. But this method is not suitable for self-fueling, because it requires professional knowledge in this area. Only experienced engineers in the service center are able to conduct the procedure.

Each method has its own drawbacks and advantages, and it's up to you to decide what method it will be easier to fill the air conditioner yourself.

On how to refill the air conditioner, you can also watch a video, where they clearly show a simple way to fuel yourself.

Signs that freon is over

There are several true signs that freon in the air conditioner ends:

1. Firstly, it's heating the air conditioner unit. Freon always acts as a cooling liquid. If it ends, the air conditioner will begin to heat up, and this can lead to a serious breakdown. Then you have to repair the air conditioner, and this will hurt your wallet.
2. Secondly, if the air conditioner starts to cool badly or, on the contrary, to supercool, then this is also a sign of the ending freon.
3. Third, the appearance of frost on the outdoor unit is also a worrying sign.

How often to fill the air conditioner

All these problems can arise ifThe conditioner does not replenish within a year or more with active use. Also, if you notice all the above signs, then it is worth paying attention and refueling the air conditioner.

Air conditioning is also refueled after repair or when transferring it to a new location. In all these cases, there is a loss of refrigerant.
