1 TECHNICAL DATA SHEET Features and uses of is a non-azeotropic blend of HFC with zero Ozone Depletion Potential et low Global Warming Potential (GWP), formulated to meet the requirements of the F-Gas Regulation in Europe which aims to reduce CO 2 emissions into the atmosphere. It is compatible with mineral traditional lubricants, alkyl benzene and also with synthetic POE, thus not being necessary to make changes in the installation. Applications "Drop-in" direct replacement for R-22 in refrigeration and air conditioning, in low, medium and high evaporating temperatures, providing an easy and long-term solution. One single replacement for R-22 in all applications except for flooded evaporators. Low Global Warming Potential (GWP) suitable for R-22 installations which had been previously converted to other HFC such as R-417A, R-417B, R-422D, R-438A, R-424A (RS44) and R-434A (RS45). Simple solution able to work both with expansion valve (TXV) and capillary systems. Due to the fact that there is no need for expensive and hygroscopic synthetic lubricants, the risk of humidity in the system is completely avoided. Thanks to its discharge temperature, significantly lower than R-22, there is no concern about oil decomposition. is suitable as a direct replacement for R-22 in low, medium and high temperatures in a great number of applications: Commercial air conditioners, splits, chillers, industrial cooling processes Cooling chambers, supermarkets, refrigerated cellars, refrigerated transport, cold-drink vending machines, milk-cooling cabinets, ice rinks. Others. Conditions for service and work Due to the fact that is a blend, it must be transferred in liquid phase or in full loads if it transferred in gas phase. In most cases there is no need to change the existing refrigerant oil, can be used directly as indicated in the conversion guidelines. In the event of a partial leak, the system can be top up with without their properties being significantly affected. Lubricants is compatible with mineral and alkyl benzene oils which are in R-22 systems, and also with polyolester lubricants. While in most cases there is no need to change lubricant, it is recommended to follow directions in relation to lubrication qualities and viscosity of compressor manufacturers. However, in systems with extensive and complex piping configuration, or in large volume of liquid containers or with very low work temperatures, it may be necessary to add a part of POE. 1

2 Environmental Data None of the components contains chlorine, so the product has ODP = 0 (ozone depleting potential). As with all hydro fluorocarbons (HFCs), has a direct Global Warming Potential (GWP), but this is counterbalanced by its low TEWI-Total Equivalent Warming Impact (greenhouse effect). Security is non-toxic, non-flammable, high security. It belongs to security classification A1 / group L1. Material compatibility is compatible with all materials commonly used in refrigeration systems which have previously worked with R-22. In general, compatible materials with R-22 can be used with. It is recommended to check with the manufacturer the particularities for equipment adaptation with regard to compatibility of materials. In existing facilities with R-22, it may be necessary to replace some joints due to the different composition of, which contains HFC's. Pressure and Temperature Tables The tables of refrigerant pressure, temperature and graphs indicate both bubble liquid point and pressure dew point. Bubble Temperature: The temperature at which liquid refrigerant begins to vaporize at the given pressure. Below this temperature refrigerant liquid is sub cooled. Pressure dew point: The temperature at which refrigerant vapour begins to condense at given pressure. Above this temperature, refrigerant vapour is considered in superheated state. Superheated vapour: To determine evaporator superheat, measure temperature and pressure line suction in evaporator outlet piping. Using P / T tables you can determine pressure dew point, with pressure measured in suction. Subtract to the dew point current temperature and this difference is the evaporator superheat. Sub cooling in the refrigerant liquid: To determine sub-cooling in condenser, measure temperature condenser outlet pipe and measure pressure condenser outlet of the same pipe. Using table Pressure / Temperature to determine bubble point of fluid from condenser. Subtract measured temperature from boiling point determined and this difference is sub cooling of condenser refrigerant liquid. Note: With the range of refrigerants RS, the average of evaporating and condensing temperatures will be the midpoint between bubble and dew temperature. 2

8 QUESTIONS AND ANSWERS ABOUT 1 Q: What is? A: is a direct substitute (drop-in) for R-22 in most applications, without effect on ozone layer (ODP = 0) and with a low global warming potential (GWP). 2 Q: What does contain? A: is a blend of HFC 134a, HFC 125, R-32, R-227ea, HC iso-pentane (R-601a) and n-butane (R-600). 3 Q: Has an ASHRAE number and which is its classification? A: Not yet, it has been requested but it s a long and slow process. 4 Q: Is subject to a phase-out according to regulations, such as CFC and HCFC A: No, none of components are subject to a gradual elimination schedule under Montreal Protocol or European regulations. 5 Q: Is non flammable and non toxic? A: Yes, is non toxic and non flammable under fragmentation conditions according to the norm ASTM It belongs to group L1. 6 Q: Can be used with mineral and alkyl benzene lubricants? A: Yes, there is no need to change to synthetic polyester oil (POE), since it operates satisfactorily with traditional lubricants. The return of the oil depends on certain design and operating conditions. In some systems with extensive and complex piping configurations, in flooded evaporators or in systems in which the accumulator of the suction line acts as a low pressure receiver, it is recommended to replace all or part (approximately 25%) of the oil quantity in the compressor with POE. See guidelines for conversion. 7 Q: What is the main advantage of? A: is the direct replacement for R-22 with the lowest Global Warming Potential (GWP) on the market. is one product to replace R-22 in all installations, except for flooded evaporators, which can only be substituted with RS-45. With there is no need to change the original mineral lubricant and it operates satisfactorily in the full range of temperatures commonly found in R-22, both in high and low. Pressures allow operating with elements from the existing installation, without having to change anything. is suitable with expansion valves (TXV) and with capillary (fixed orifice) systems. Because is a direct replacement (Drop-In), it is the perfect solution for food industries that cannot stop their production to replace R-22 for R-404A. 8 Q: Can be used to recharge an installation containing R22? A: The standard recommendation is not to mix refrigerants. Adding to a R-22 system will not form an azeotropic blend thus will not generate higher pressures. Not only theoretical tests but also trials carried out in existing installations suggest that may be used to top up R-22 leaks in any proportion without affecting the performance of the equipment. 9 Q: Which is the compression ratio of? A: Having high compression ratios could result in increased energy expenditure and damages to the compressor; has a compression ratio equal to R Q: Is as efficient as R-22? A: Tests show that has a higher coefficient of performance than R-22 and therefore, it is more efficient energetically. 8

9 11 Q: What tests have been carried out with, and what are the results? A: In conversions from R-22 to, it has been verified that is a direct replacement (Drop-In) and that no oil change or any other modifications are needed in the installation 12 Q: What is the glide? A: 4,2ºC approximately. 13 Q: Should be charged in liquid or gas form? A: Because is a blend, it is recommended to load the system in liquid phase. However, if the entire contents of the bottle must be introduced, it can be charged in gas phase. 14 Q: Have containers of dip tube? A: It depends on the type of container. All blue containers of Gas Servei S.A. have it. In the case of not having it, it is recommended to reverse container. 15 Q: Is included in Significant New Alternatives Policy Program (SNAP)? A: Not yet, but the process has been initiated. 16 Q: How are pressures compared to R-22? A: The pressure discharge is about 0,5bar higher than R Q: What is capacity compared to R-22? A: The capacity of matches R-22 from high to low temperatures across the temperature range where R-22 is commonly found. 18 Q: How are the operating temperatures compared to R-22? A: discharges temperature are lower than those of R Q: What are flammability characteristics? A: is not flammable at room temperature and atmospheric pressure, and has the same classification as R-410A, R-134a, R-404A, R-409A (FX56), R-507, etc. 20 Q: What are the decomposition products resulting from combustion? A: The decomposition products resulting from exposure to a high temperature source are similar to those formed by R-22 when exposed to fire. The decomposition products in each case are irritating and toxic, and self-contained breathing equipment should be used if such a possibility exists. 21 Q: Must any special precaution be taken when using? A: No special precautions should be taken with. As with all refrigerants, common sense and good practices are always recommended. The use of hygroscopic synthetic lubricants (POE) can be avoided with the use of, so there is no need to take special care with moisture even though, the ingress of moisture is to be avoided at all times. 22 Q: Is compatible with refrigeration and air conditioning systems designed for R-22? A: Yes, is compatible with all materials commonly used in systems that were designed and charged with R-22. As with R-22, magnesium and zinc alloys should be avoided. 23 Q: Can be recovered and recycled? A: Yes, can be recovered and reused after a cleaning process, and delivered to an authorized waste manager for further regeneration. 24 Q: Which are the guidelines to change R-22 to? A: The procedure to replace R-22 with is simple. After recovering R-22 and fully evacuating, use the same type of lubricant, replace the filter / drier and introduce around the same amount of as the original R-22 charge. See guidelines for conversion. 9

10 25 Q: What is the price of compared to other alternatives? A: is competitive in price with regard to other R-22 substitutes. 26 Q: Is approved by compressor manufacturers? A: The individual components of are widely used in compressors produced by the main manufacturers. 27 Q: What is the coefficient of performance (COP) of compared to R-22? A: Tests show that provides higher COP than R-22, depending on the application and equipment. 28 Q: What is the specification of? A: complies with the specification of refrigerants ARI for all the fluorocarbon refrigerants. 29 Q: What are the effects of high exposure by inhalation of? A: As with all CFC, HCFC and HFC that are the base of refrigerants, high exposure to can produce anaesthetic effects. Very high exposures may cause an abnormal heart rhythm and be fatal as with all CFC, HCFC and HFC. 30 Q: What is the flash point, explosive and ignition temperature of? A: is listed as a non-flammable refrigerant, as defined in ASHRAE test EN and therefore, has no flash point or explosion limits. The ignition temperature of has not been determined, but is expected to exceed 750 C. 31 Q: Can be used in flooded evaporator systems? A: No. 32 Q: What kind of leak detectors should be used with? A: You can use the same leak detectors as in HFC. 33 Q: What would be the effect of a large release? A: As with other refrigerants of the same kind, the area should be evacuated immediately. The vapour can concentrate at ground level and at poorly ventilated low areas so the dispersion can be slow. You must proceed to ventilate the area before entering it. 34 Q: Is available in disposable bottles? A: Yes, but only for export outside Europe. 35 Q: Can be employed in systems originally designed for R-22 and then used with hydrocarbons (HC)? A: Although there are not tests conducted with hydrocarbon systems intended to replace R-22, we believe that would be appropriate for this, even though the mass of the refrigerant charge should be larger. 10
