Is R152a colder than R134a?

Is R152a colder than R134a?

Turns out, r152a is also colder than r134a can get your ac, and since it’s not regulated, it is cheap and you can find it everywhere.

What is R152a refrigerant used for?

R152a is commonly used as a propellant in aerosols, as a foaming agent, or as a component of refrigerant blends, however, its classification as a slightly flammable refrigerant has limited its use in automotive and commercial refrigeration.

How much is a bottle of R410a?

R410a costs around 70$ per 25 pound jug. To buy a jug you need a CFC certification. Cost per pound could be anywhere from $25-$75 per pound, not including labor in some cases.

Is R152a flammable?

Major drawback of R152a is its flammability. However in case of a GWP limit of 150 R152a is remaining a hydro-fluorocarbon (HFC) subject to re-enforcement of regulation. The combustion gas of R152a contains harmful hydrogen fluoride.

Can you mix R152a with R134a?

(i) The mixture of R152a and R134a works safely in the system without any system modification. (ii) The discharge temperature is found to increase with the mixture of refrigerants and higher discharge temperature was recorded for 70:30 mixtures of R152a and R134a.

Is R152a compatible with mineral oil?

I found this in an online book which says that r152a is partly soluble in the mineral oil used in SO2 systems.

When can you use a disposable cylinder to recover refrigerant?

Never overfill refrigerant storage cylinders because: The internal pressure of the cylinders may rise in heated areas and cause an explosion. When can you use a disposable cylinder to recover refrigerant: Never.

Why is R410a so expensive?

The first is due to the current worldwide shortage of R125. As R125 is one of the two component refrigerants of R410a (the other is R32), any shortage of this gas significantly affects the production and consequently the price of R410a.

Is r152a compatible with mineral oil?

What lubricant is used with HFC 134a refrigerant?

Most HFC-134a systems use a synthetic lubricants called polyalkylene glycol (PAGs) or polyol esters (POEs).

Can you use R12a in a R134a system?

It’s illegal to vent R134a into the atmostphere! You don’t just blow it out! Just adding R12a to a 134a system doesn’t work very well because a 50/50 mix is very inefficient. If you don’t have a vacuum pump, you can still make it work though.
