Common in most household refrigerators is a significant home appliance. It’s basically equipped with thermally insulated chamber and heat pump. It always a wonder how heat and cold air work together. However it more on mechanical and electronic and maybe chemical knowledge. read some Important steps in household Refrigerator Gas Filling process.
The amazing part of the refrigerator is that heat is generated and directed inside the fridge but on the external areas. What happens? The inside will be cooled to lower and unbearable temperatures. This in other words meaning below normal temperature thus conserving all the foods and drinks in the refrigerator.
Refrigerators can be used by families as home appliance, companies and also institutions. They main task is to keep lower temperatures and reduce bacteria’s from reproducing and thus avoid food from going bad.
Enough with the tasks and mechanism of what works where. Today in our article we focus on how to refill gas on the refrigerator. With all the questions which linger in our minds about Refrigerator Gas Filling.
Is the gas dangerous? Do I need experts to refill my refrigerator? How much does the gas go for? One can’t stop with all this question. Here we answer and educate you to fully satisfaction.
Which gas is used for refrigerator?
Before one fills Refrigerator Gas Filling, it’s proper for you to find what best for your appliance. There different gases for different use. Nonetheless in the new era refrigerators are using refrigerant by the name HFC-134a. We also have 1, 1, 1&2 Tetrafluoroethane, sounding to scientific. In greater and advanced countries Indian and Europe countries R-600a/isobutene are the gases to use for your Refrigerator Gas Filling.
The above gas are environment friendly, making them healthy for human. Though in the past years gases used haven’t been safe and with new invention the recent and upcoming gases are best for the
A gas with halo alkane refrigerant which have the thermodynamic properties are popularly known as the R-134A. This type of gas has no additional features or components, it is the best gas for refrigerators.
Itgets a high rank since it has thermodynamic properties which are closely related to R-22. This the alternative for the R-22 as most people are using it more on vehicles and AC. As we have seen the common gases for the new refrigerators are 1, 1, 1&2 Tetrafluoroethane, hydro fluorocarbons and pentafluoroethane. R-407C replacing Freon which was considered as unsafe for the environment.
Working and having the same properties of R-134A and R-407C. The R-404 has conditions as it only works for with temperatures of -45 degrees to 15. Yes this makes it unique for transport and industrial uses.
It a combination of two popular gases thus producing the R-410A. Very safe for the environment and other uses. This gas has the highest refrigeration capacity and used on commercial refrigeration and all coolant units.
With all above types of gases and only the best for your refrigerator. We now come to the process of filling the appliance. It can be done by an expert or simple the owner, have the right equipment and check for possible leakage points.
Refrigerator Gas Refilling process.
This a way to Refrigerator Gas Filling which maybe half or none and causing the refrigerator not to cool/conserve the food and drinks to the right temperatures. You need the correct gas as we have highlighted them and you can follow the steps below.
- First check the compressor and where you have the process tube.
- When get here now connect a valve on the compressor process tube.
- On the same gadget they are enclosed instruction read and also tighten all the screws.
- Ensure the compressor is well attached.
- Enter the hose mouth to the already inserted valve then open it.
- Again I insist on you reading all the instruction on the valve.
- Now check the gauge it should be off and well fixed.
- It is sometimes tricky on which side to turn off. Using the valve open any of the side and listen to the gas escapes. Here you will know which side to turn off.
- The compressor tube has gauge attached and has the negative and the positive side. It the “0” scale which is right green and the black part representing the vacuum or negative side.
A negative sign indicates your refrigerator has no coolant/gas. Remember this what you need to preserve the stuff inside. With the above procedure we have connect the valve ensured its tight and no leakage. On checking the gauge you will note how much gas will be refilled according to the readings.
- Now pick your coolant or gas can according to what fits your refrigerator. Using the gauge let the air flow
- For longer hose first close the valve which is connected to the compressor. Open the gas can then open the valve just slightly to ensure you hear the gas flow. Now quickly slacken the valve and constrict the hose then turn off the valve at the gauge.
- Assuming we are using the R-134A gas open the valve and keep the can upright.
- Give the gas sometime to flow inside the refrigerator. In like 10 minutes time check the activity happening on the gauge any increase or decrease which is bad. An increase should happen as we are aiming at getting 3-lbs. use the valve to regulate the pressure.
- Again open the valve let the gas flow keep checking in intervals of 10-15 min. check how tight the valve is and adjust.
- Finally check your gauge if it’s at the right lbs. you are good to go, the process is very simple but needs a lot of care. Check for leakages and how you set all the gauges.
It should be noted once refilled the gas should go for some years. Yes I know some will say: my refrigerator coolant/gas leaks out quickly forcing me to fill often? When this happen please check your piercing valve whether well tighten and the type. Stop leaks might also come in handy but in most cases a leak shouldn’t happen. The mistake will be at the valve check fix and your refrigerator will be cool as always.
