How to fix air conditioner freon

If you have noticed that your air conditioner deviated in his work from a normal regime without your intervention (heavily cools the air or does not cool at all) - it is quite possible that it needs to refuel freon. It is possible to conduct it yourself, having a thermometer, a balloon with the desired refrigerant, a pressure gauge station, a cylinder with nitrogen, a vacuum pump and refueling scales. And we will tell you how to do it right.

First you need to decide which refrigerant is necessary for the full work of your air conditioner. Such information can be found in the instrument manual. Mainly in the work of modern climatic equipment, manufacturers use two types of freon - the R410A brand and the R407C brand. Both types are absolutely safe for the environment and the person.

Now exhibit the temperature of + 18c and cold mode on the device.

Next, it is necessary to check the system for tightness, and its pipelines - for moisture and air. From the first to get rid of a cylinder with nitrogen, from the second - vacuum pump.

Immediately before Freon refueling, the calculation of the refrigerant required to refuel is required. For this, there are several techniques that use the principles of calculating the mass, by pressure in the system or temperature (overheating or supercooling). The required amount of refrigerant is measured by weight.

We refuel the air conditioner by Freon using a pressure gauge station. To do this, we need a large tube that goes from the external unit of the air conditioner. We open the cap and connect the pressure gauge to it. Now turn on the system at normal speed and control the temperature of the air emerging from the device using the thermometer. The signal to the end of the refueling will be the moment when the thermometer will start moving upwards.

With refueling air conditioner Freon, watch also the testimony of the pressure gauge. In normal weather and air temperature indicators from + 23c, it should show 4-5 bar.

All data obtained during the procedure are checked with the manufacturer's tables that are attached to the device. If you do not have them - look for the necessary information on the company's website that has released your air conditioning.
