Chiller R-513A is currently considered as an alternative for the replacement of R-134a in existing water chillers.
What should you know about R-513A as a replacement in chillers? R-
- R513A is an azeotropic mixture of R134a (44%) and HFO-1234yf (56%).
- R-513A is a non-flammable refrigerant that has a lower GWP than R-134a, but similar performance.
- The mixture has low toxicity and flammability, along with a 56 percent reduction in GWP.
- R-513A has a GWP of 629, but as a weak point with slightly lower efficiency than R-134a.
- R-513A is a “Drop-in” direct replacement for R-134a in existing high and medium temperature commercial and industrial refrigeration equipment.
- The R-513A is presented as an excellent alternative in chillers in centrifugal and screw compressors.
- R-513A is a low GWP, non-flammable (A1) alternative refrigerant to R-134a that enables chiller manufacturers to comply with future HFC regulations.
- All Danfoss Turbocor series compressors produced as of December 2017 are compatible with R-134a and R-513A.
- By providing efficient R-134a chillers that are future compatible with R-513A, the long-term investment customers make in their chillers is protected.
- YORK Company’s chiller offering of R-134a products that can be used with R513A provides peace of mind.
- Carrier has announced that its AquaEdge 19XR and 23XR and AquaForce 30XV / XA chillers are compatible with R513A refrigerant.
- The higher vapor density of R513A on the suction side of the compressor results in a higher mass flow rate.
- When using R513A the mass flow rate increases about 15%.
- Depending on the diameter of the pipes, a higher mass flow causes a significant increase in the pressure drop in some pipes, and an increase in the compression ratio of the compressor.
- R513A is not flammable in air under normal conditions.
- R513A is also known under its trade name Opteon XP10.
- R513A is compatible with the equipment, components, lubricant and gaskets of an existing R-134a installation.
- R513A is compatible with synthetic POE oils.
- R-513A is a substance with very little toxicity.
- R-513A vapors are heavier than air and tend to collect near the ground.
- Very high atmospheric concentrations of R-513A can produce anesthetic effects and suffocation. High exposures can cause abnormal heart rhythm.
