What’s happening in refrigerant September 2019?
- Refrigerant pricing has no change in September, with the NZU’s staying static at around the $24 price point. The market continues to wait for expected increases with the outcomes of the government’s review of the ETS.
- A number of “new refrigerants” have come into the market as manufactures work to meet strict global HFC phase down milestones.
In New Zealand R513A is now available on the market, which we see as a short term transitional refrigerant for existing systems on R134a.
R513A has a low GWP of 631 and is an excellent capacity and energy efficiency match to R134a.
Transitional refrigerant R513A
R513A is a zeotropic blend of 56% next generation synthetic F gas refrigerant hydrofluoro-olefine (HFO) and 44% R134A.
Many people are surprised to learn that what they think is a new refrigerant is actually a blend of an old one.
R513A is designed to replace R134a in domestic, commercial and industrial refrigeration applications as well as in air conditioning, liquid cooling and PAC.
To use in an existing system a system will require a retrofit and systems will need to be assessed for compatibility.
It can be used in direct expansion and flood systems.
It is currently more expensive at more than double the cost of R134a as HFOs are priced at the higher end of the market, with demand for the refrigerant coming with decreasing availability of R134a globally.
It has almost identical physical and thermodynamic properties to R134a:
- Performance and efficiencies closely match that of R134a.
- Non-flammable with a safety classification of A1.
- For oil dependant systems R513a is fully compatible with polyolester oil.
For those that have R134A systems and are looking for a short term transitional refrigerant before investing in a natural refrigerant, R513A has seen to be a suitable choice providing good performance outcomes.
