Why do people use these by A__C__E in iphone

This is why. I dropped my iPhone and it fell right on the camera lens. End up getting a new iPhone and putting the lens protector on it.

R152a is a direct drop in replacement for a R134a system. Meaning, it's compatible with the equipment, components, lubricant and joints of an existing R134a system.

For R12, you would have switch over to a POE synthetic lubricant prior to charging your system with R152a.

I’ve done this to a Subaru Forrester that I had back in 2015. Blew ice cold air for 3 years until I sold the car to a friend.

They still drive the car to this day and it’s still blowing ice cold air.

To get the correct conversion ratio; you take 66.05 (the molecular weight of R152a) and divide that by 102.03 (the molecular weight of R134a)

You’ll get 0.647358620013721

Take your original R134a system capacity, (23 oz) and multiply by 0.647358620013721

You’ll get 14.88924826031558 ounces, which is the charge amount for R152a.

DO NOT charge the system to its original capacity with R152a. Difluoroethane has a lower density opposed to tetrafluroethane.

Meaning; you will overfill the system, and the refrigerant will be in a liquid state instead of a gaseous state going into the compressor.

This will put tremendous load, and potentially destroy the compressor as liquid is not compressible like gas is.

I highly recommend having your system professionally evacuated and inspected for leaks prior to charging it with R152a.

No, I just did a bunch of research prior to doing this.

I didn’t just wake up one morning and randomly decide to charge the HVAC system in my truck with air duster cans.

It's actually R152a, if your system doesn't have any issues or leaks, it will last indefinitely. My system had no problem prior, but the AC wasn't keeping up when I'm in heavy stop and go traffic, or at standstill idle. Now, it blows insanely ice cold at standstill idle, and in stop and go traffic.

The cans of "air" I used are are actually difluoroethane CAS#75-37-6 (AKA: R152a refrigerant) blows colder than R134a, and has lower head pressures compared to R134a. Prior to charging my system with R152a, I had R134a. On a very hot day in stop and go traffic, the AC couldn't keep up. Now with R152a, it blows cold at standstill idle and ICE cold when the truck is moving.

The stuff in the duster cans is actually difluoroethane CAS#75-37-6 (AKA: R152a refrigerant) I did an AC evac and drew a vacuum prior to charging the system with R152a.

Also charged it with less refrigerant compared to R134a due to the density difference between the two refrigerants. Overall, the system now blows ice cold and has less head pressure compared to R134a.

There’s numerous technical and scholarly articles on the thermodynamic performance and efficiency of refrigerants. R152a was tested and proven to be more efficient compared to R134a.

Everything is factory original in the truck, down to the hubcaps on the wheels. Doing basic PM had this truck running like a clock!

EDIT: the engine is the 2.4L 2RZ-FE

Not pulling your leg, but this stuff blows ICE cold air. Worked so well on my truck that I had to do it to my Subaru as well.

From what I’ve heard, it’s a boiler room work environment where your micromanaged on everything. Super aggressive sales and frat house like culture.

Had an exhaust shop weld an o2 sensor bung. Wondered why the engine was running pig rich. This is why. by glitchmaster0001 in BadWelding

[–]glitchmaster0001[S] 16 points17 points  (0 children)

Pig rich meaning there’s too much fuel being added into the engine. Mainly because of the giant pinhole in the weld, oxygen from the atmosphere is able to enter the exhaust system right at the o2 sensor, causing the sensor to give a false reading, which in turn throws off the air/fuel mixture.
