Thread: York A/C compressors - repairable or not?

HR or maybe FR-12 from memory

Thanks Dave

While there may be a better replacement, at the time Care 30 was installed we had a business that were running Care products through all the freezer units, trucks and the warehouse and had found it to be more efficient than the CFC refrigerants and not carcinogenic like some of the alternative CRC replacements.

Now that I have Care 30 in the system, changing to an alternative would require a complete evacuation of the system of Care 30 and hydraulic oils, replacement of the drier and then installation of a refrigerant that I do not have. Remember I have a 1/2 full 9KG bottle of Care 30 which should last the life of the vehicle.

BTW: I should explain, my estranged from the family brother, was the "fridgy" who installed the refrigerant and hence I can't use him for maintenance.

I don't know about any newer or other types of York compressor, but the cast iron 12 cfm reciprocating units used in Clima air conditioners on mining equipment were repairable. This is one of the reasons almost all mines in Qld. then specified Clima air conditioners. Clima also used repairable electric motors in the fan sections. A machine with inoperable a/c is a "machine down" and no pit boss wants to have a big machine down waiting for parts from a capital city or overseas.

fair enough, but from what I recall of the FR-12 (or hr-12) its compatable with the 3 primary varients of refrigerant oils which was part of the reason it was chosen for my fridge. We had no way of checking or changing the oil in the compressor.

Good luck getting a compatible set of guages or are you going to do a sight glass or cold line fill?

Not a problem Dave.

Care 30 is compatible with regular mineral oils http://www.actrol.com.au/techPapers/oilChart.pdf and you just use your regular gauges as Care 30 operates at similar pressures to R12 and R134A and has a similar volumetric effect to both those refrigerants. BOC | Gas2010 | Natural Refrigerants

Hydrocarbon gas isnt legal in australia in a vehicle or system that was originally designed to operate on R12-R134A etc etc as a drop in replacment gas.ive never seen a system work better on it.

air conditioning gas is now classified and sold as a gas-as hydrocarbon gas in a bottle is as dangerous as any other flamable gas.any one can walk into a shop and buy and transport HYCHILL etc.

ITS illegal to remove R12-R134a ETC or service a system without national acreditation.

WHAT THE CHANGE IS-IF YOU USE AIR CONDITIONING AND ITS NOT USED AS IT WAS INTENDED BY THE MANUFACTURER and you havnt got written permision to use it YOU ARE NOW RESPONCIBLE FOR ANY ISSUES THAT ARISE AND INDUCTION OF ANY PEOPLE THAT IN THE FUTURE MAY WORK ON OR NEAR IT.
if someone works on the system and its not clearly marked you are liable.

I must ask the local auto electrician about this... they use hydrocarbon HR12 in everything. Burson Automotive will sell it to anyone, no licence needed they say, I checked last month.

I believe you are incorrect. AFAIK Queensland is the only state which specifically prohibits retrofitting of HC refrigerants.

The AU code of practice:
http://www.arctick.org/pdf/Automotive_RAC_CoP.pdf
States that each state has its own legislation on HC refrigerants for automotive use.

SA Hazard alert:
http://www.safework.sa.gov.au/upload...azalert84a.pdf
Note the wording - it does not state that it is illegal. Just that retrofits "should" only be conducted to sustems where the manufacturer has said it is OK.

Unfortunately some of this information that is less than correct. Hydrocarbon and Natural refrigerants are permitted imports. In fact they are almost the only refrigerants that don't need an import permit. "If the equipment you wish to import is designed to operate on a Hydrocarbon refrigerant such as Ammonia (R717), Propane (R290), Isobutane (R600a) or any other natural refrigerant, you do not need to apply for a pre-charged equipment licence but you must supply to Customs (or your Customs Broker, or Freight Forwarder), documentary evidence (see below) confirming that this is the case." Importing cars, boats, caravans, motor vehicles or any other equipment that may contain refrigerant gas into Australia - What you need to do

Hydrocarbon refrigerants were only ever banned for automotive use in NSW and that ban was lifted in the late 1990's when numerous university research projects proved that it is impossible to create an "overpressure" ignition event with the only source of hydrocarbon being the car air-conditioner. "Around the time Australian Refrigeration Council (ARC) was formed, the NSW ban on Hydrocarbon Refrigerants was lifted which brought NSW into line with all the other states, including Victoria who never placed a ban on the use of Hydrocarbon refrigerants. The NT revoked a cautionary notice they had for HC shortly after NSW, but Queensland still has a HC handling licence requirement. Now interestingly over 15 years of Victorian experience has provided long term data involving the use of HC’s in mobile systems. " http://www.airchill.net.au/auto-moti...ing-gases.html

In respect to my vehicle, it is and has always been labelled as containing a hydrocarbon refrigerant.
