Thread: 1985 Landrover county 110 aircon

There has been a few comments on HyChill recently. A few questions, since you're a fridgey!

Is there any reason I couldn't use HyChill in my County system? I.E. same drier, etc as used with R134a now?
Why did you choose HyChill over R134a?

Cheers.

I didn't choose Hychill,

As far as I know there is no reason you can't use Hychill.
Hychill and Ozchill refrigerants are hydrocarbons blends, usually blends of Propane and Butane.
Hydrocarbons are flammable/explosive to varying degrees when mixed with oxygen.

Don't get me wrong these refrigerants offer great improvements in efficiency and they are relatively cheap and from what I have heard the amounts of refrigerant required in a car shouldn't be enough to cause a problem.
The problem with hydrocarbon refrigerants is there are no set rules. As a refrigeration mechanic no one can tell me what standards I have to meet, what safety requirements have to be conformed to.
There are recommendations that if you search for them and are lucky you may find them and then there is hearsay. The hearsay is usually generated by the refrigerant manufacturers from either side of the argument.

The Company I work for has decided not to use these refrigerants until the rules have been set in concrete. We recognize the benefits but we recognize the risks especially when some of the equipment we work on requires 16 kg of refrigerant or more, can anyone say big buddaboom.
