- R1224yd is a refrigerant designed for use in centrifugal chillers, binary cycle generators and waste heat recovery heat pumps, blowing agent, spray solvent and cleaning solvent, with low impact on the environment. R1224yd Is ideal replacement for equipment working with R245fa.
What should you know about the R1224yd (Z) in chillers?
- In October 2017, the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) granted the AGC company the certification for AMOLEA R1224yd.
- ASHRAE certification of R1224yd is expected to accelerate its adoption in a wide range of equipment around the world.
- It has a very short atmospheric lifetime and therefore a very low GWP value.
- Its ODP is almost zero and it possesses the excellent stability required for refrigerants.
- R1224yd (Z) refrigerant is a unique substance, which allows partial refrigerant recharge even if refrigerant leaks.
- R1224yd (Z) refrigerant has high stability, therefore there is no change in performance and it does not cause problems such as corrosion after prolonged use.
- The R1224yd (Z) refrigerant has high efficiency, provides high cycle efficiency, and indirectly contributes to a lower environmental impact through the reduction of electricity consumption.
- Companies such as EBARA Refrigeration Equipment & Systems have adopted R1224yd (Z) refrigerant for their RTBA model centrifugal chillers.
- Through a retrofit service, R1224yd (Z) refrigerant can be used in existing centrifugal chillers that are installed.
- When retrofitting chillers using R245fa refrigerant is required, R1224yd (Z) refrigerant requires some minor parts of the chiller to be replaced.
- Since R1224yd (Z) refrigerant is non-flammable and has low toxicity, good safety and reliability can be maintained.
- R1224yd (Z) refrigerant is exempt from the Fluorocarbon Emissions Control Act.
- R1224yd (Z) refrigerant is easy to handle and has low pressure. R1224yd (Z) refrigerant has the same performance (COP) and cooling capacity as R245fa.
- Since R1224yd (Z) refrigerant is non-flammable and low in toxicity, the same safety and reliability as before can be maintained.
- Although the effects of R1224yd on elastomers are equivalent to or less than those of R123 and equivalent to those of R245fa, degradation due to elution may occur in some materials..
- Remember that plastics and elastomers can exhibit different properties depending on the mix ratio, types and amounts of additives used, and processing conditions.
- Can be adapted for the equipment used for HFC-245fa and HCFO-1233zd(E) without changing the design.
- The Tokyo National Stadium, the main venue for the last Olympic Games, uses R1224yd for air conditioning with an RTBA turbocooler, manufactured by Ebara Refrigeration.

Lubricants used with R1224yd:
- The R1224yd is mutually soluble with refrigerantion oils, such as P O E, that are used with H F C refrigerants, and also with naphthenic oils that are used with H C F C
- The solubility in synthetic oil of HFO-based refrigerants such as R1224yd (Z), is higher than that of HFC refrigerants. R1224yd (Z) refrigerant dissolves with both synthetic oil and mineral oil.
