Can I Use Automotive R134A In A Refrigerator? [Don’t get bogged]

No. R 134A is developed for the high needs of an automobile’s air conditioning and, owing to pressure variances, cannot be applied in freezers.

Although it is efficient, the pressure and temperature requirements for a vehicle’s air conditioner and a refrigerator’s compressor are different.

The specific composition of refrigerant used in a refrigerator is designed for far lower pressure and temperature conditions than those present in an automobile.

In addition to this, refrigerators often use R22, R32, or 410A-based coolants as their cooling agent.

How to Recharge Your Refrigerator Using Freon 134a

YouTube video

The video shows how to install 134a freon to your refrigerator. First, you’ll need a few components, including a bullet piercing valve, freon, an air conditioning conversion adapter from r12 to r134a, a multi-bit screwdriver, a freon gauge, and a fridge.

After opening and inspecting your refrigerator, determine whether it needs freon. Then, the first step in adding freon is to position the bullet-piercing valve closest to the compressor. 

This bullet piercing valve has two adapters for various tube diameters; choose which one matches your tube size.

Afterward, work on installing the piercing valve. This piercing valve’s purpose is to puncture a hole in the tube so that freon may be introduced. 

It also functions as a valve that opens and closes to allow you to add, remove, and check the amount of freon. As you work on it, make sure it’s tight.

After that, uncap the piercing valve and replace it with the conversion valve. If you have a freon system and want to know how much is left in it, attach the gauge and open the valve.

After verifying the amount of freon you have, put some of it in your refrigerator if you need more. 

Remove the freon cap and place it in the recharge hose when adding freon. Always consult your owner’s handbook to determine how much freon your system requires. 

You’ll avoid overcharging it this way. When you’ve reached your desired freon level, close the valve, remove the adapter, and replace the cap.

Frequently Asked Questions

Is it true that all R134a refrigerants are the same?

Yes, practically all r134a refrigerants are the same. However, the qualities of leak detection in refrigerants might vary.

What pressure does 134a operate at in a refrigerator?

A standard pressure gauge is used in a 134a refrigerant system. The coil runs at a pressure of 57 pounds per square inch gauge for the maximum temperature. 

As a result, the common pressure gauge for R134a ranges from 22 to 57 pounds per square inch.

Is the R134A Freon used in freezers the same as the R134A Freon used in automobiles?

R-134a, an HFC, is commonly used as a refrigerant in refrigerators manufactured between 1995. The present-134a is a refrigerant found at most auto parts stores and used in refrigerators and automobiles. 

Generally, the compressor will be locked up if the incompatible refrigerants R-12 and R134a are used together.

Is it accurate to say that all R134a refrigerants are the same?

There is no difference between brands unless there is an increase in R134A indicated on the label. Some come with a leak sealant that you should never, ever use.

What is the Environmental Issue Of Synthetic Refrigerants?

CFC refrigerants were identified as a substantial contributor to pollution and ozone layer depletion in late 1980s scientific studies.

Despite their effectiveness, CFCs and HCFCs had to be phased out, and the majority of them were finally prohibited, following the Montreal Protocol laws of 1989. This restriction had little effect on HFCs, allowing them to dominate the market.
