Medium-term replacements are R407A and R407F. Now, various refrigerant gases i.e., R32, R410A, R22, R290, etc. As the refrigerant leaves the evaporator, the refrigerant has to be in 100 % vapour form, to avoid ingress of liquid refrigerant inside compressor as the liquid is incompressible. But, these numbers won’t do you any good if you don’t know what refrigerant you are dealing with and what the refrigerant’s boiling point is at each pressure level. Refrigerant properties Application ranges Overview lubricants to the digital Refrigerant Report. Water for example cannot be used below 0 Deg C. Low Condensing Pressure. There are no reports of human respiratory sensitization. Applications for R-401B are in normally lower temperature R-12 refrigeration locations and in transport refrigeration, and in R-500 as a direct expansion refrigerant in air-conditioning systems. When moisture is present in the form of water it may lead to icing within the evaporator coil and choking of the thermostatic expansion valve. Research has found that the ozone layer is thinning,   due to emissions into the atmosphere by the substance like chlorofluorocarbons (CFCs), HydroChloroFluoroCarbons (HCFC), halons and bromides. HFO/HFC blends an alternative for the future. However, they are relatively high in cost and are flammable to a certain extent. Due to the nature of R410a properties which is of a HFC (hydrofluorocarbons) refrigerant, it does not has any ozone depletion potential (Zero ODP) and thus introduced as a greener choice for R22 for use in both residential and commercial air-conditioning products. Due to a rapid R22 phase-out. Summary. Refrigerants should have low freezing point than the normal operating conditions. Home Water&Steam Air Refrigerant Define Mixture Moist Air Pure Fluild .

However, they have the potential for global warming. Its high GWP makes it unsuitable for future use, and it’s close to a rapid phase-out. R404A is an HFC blend designed excessively for commercial refrigeration. Due to the nature of R410a properties which is of a HFC (hydrofluorocarbons) refrigerant, it does not has any ozone depletion potential (Zero ODP) and thus introduced as a greener choice for R22 for use in both residential and commercial air-conditioning products. When coming in contact with metal parts like piping and compressor must not cause any sort of electrochemical corrosion. The presence of moisture in lubricating oil may deteriorate properties of lubricating oil and formation of metallic or other sludge which may lead to clogging or chocking of valves, filters, and other oil passages. General properties of refrigerants and requirements. While buying Air conditioners , it becomes necessary to understand the difference between R32 and R410A or any other refrigerant. CFC and HCFC refrigerants (Freon, Arcton, etc.) High latent heat of vaporization is desirable in a refrigerant. The cooling properties of R32 is similar to that of R410a. R32 is also more energy efficient than R410A. R410A refrigerant is a leading high pressure alternative to R-22, comprising R-32 and R-125, for air conditioning and refrigerant applications for new equipment. Leaks can be detected by smell, using soap solution over the connections, using pressure testing method by keeping the line under pressure for 20 to 30 minutes to check for a drop in pressure. The Chemistry; Both R32 and R410a belong to the same family of Refrigerants i.e. However, the compressor must use a synthetic polyester lubricating oil. Classification: Not classified as irritant Acidic corrosion decreases alkalinity in oil. Details. It is more effective for reducing global ozone layer depletion and also performs faster. R32 refrigerant is the short name for CH2F2(difluoromethane). 23, NIST thermodynamic and transport properties of refriger-ants and refrigerant mixtures – REFPROP version 6.01, Stan-dard Reference Data Program, National Institute of Standards and Technology, 1998). HFCs like R-410A, R-32 and R-134 refrigerants are better than HCFCs and has no effect on the ozone layer. Conclusion. all these properties make R32 a promising choice for the present. Research says that the erratic launch of rockets causes a much greater depletion of the ozone layer than CFC. R-410A, also known as Puron, is arguably becoming one of the most popular refrigerants in the world. A familiarity with these dia-grams will make this chapter easier. R410A Refrigerant is widely used as a refrigerant in many air conditioning applications, usually packaged in rose colour cylinders. To be able to condense high-temperature vapour refrigerant into a liquid refrigerant by passing outside hot air in summer via a fan over condenser coils, the refrigerant must have high latent heat of vaporization. They are not in the order of precedence as overtime priorities change when the impact on the Ozone Layer is considered the most important. Gaz réfrigérant R410a R410 vente en gros à prix réduits bouteilles réutilisables de 1 kg jusqu'à 40 kg It is widely used in medium and low temperature refrigeration especially in the Refrigerant development and legal situation Stratospheric ozone depletion as well as at- mospheric greenhouse effect due to refriger-ant emissions have led to drastic changes in the refrigeration and air conditioning tech-nology since the beginning of the 1990s. Refrigerant with a high dielectric strength avoids short circuits when refrigerant comes directly in contact with motor windings in a hermetically sealed compressor. Perform a halide leak test detection on a refrigerant that are Halogenated Hydrocarbons (Freon compounds). In certain concentrations and the presence of an open flame such as a gas range or a gas water heater, R-12 and R-22 may break down and form a small amount of harmful phosgene gas. Refrigerant R454b is a mildly flammable low global warming potential (GWP) hydrofluoroolefin-based refrigerant to replace R410a in new equipment designs. Due to the chlorine molecules’ ability to destroy the earth’s Ozone Layer by converting it to oxygen the international communities have agreed through a number of conventions to bring about its phase-out of such refrigerants. R-410A, sold under the trademarked names AZ-20, EcoFluor R410, Forane 410A, Genetron R410A, Puron, and Suva 410A, is a zeotropic but near-azeotropic mixture of difluoromethane (CH2F2, called R-32) and pentafluoroethane (CHF2CF3, called R-125) that is used as a refrigerant in air conditioning applications. R12 was completely phased out due to its ozone depleting potential (ODP) = 1 and Global Warming Potential (GWP) = 10000. r22 has a boiling point of -40.7°C, developed primarily for low-temperature systems. This gas has less exposure to Global warming potential as compared to R22, and companies use it as a replacement for the same.
