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. Belonging to the group of HFC refrigerants, R32 stands out thanks to its low GWP value of 675 and ODP of 0. This blend refrigerant is similar to R-401A except, it is higher in R-22 content. R-410A is also being considered in some medium temperature refrigeration applications. It was discontinued after being listed among hydrochlorofluorocarbon, i.e., HCFCs. With proper system design, it has been shown to give equivalent or better performance than R407C. Power Saving Guide – ISEER, EER and BEE Star Ratings. The replacements of the CFC and HCFC refrigerants are the HFC’s. R-410A Pressure Chart. Fluorocarbon based refrigerants are safe. It is thermally stable and does not decompose until the temperature is well over 1000°C. 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. R32 as a single component refrigerant is attracting attention not only as an alter-native to R410a in developed countries but also as … Daikin, One of the Leading AC manufacturer, is using R32 refrigerant which has GWP (Global warming potential) of 675. R407C is a zeotropic mixture consisting of 23% R32, 25% R125 and 52% R134a. Chlorine molecules have the ability to destroy earth’s Ozone Layer by converting it to oxygen. The dye escapes from the leaky sites and shows up as a green or yellow solution. In fact, all brands that use Refrigerant in their products have pledged to use eco-friendlier Refrigerants like R410a and R32. If the industrial plant is built outside or on the roof of a building, the escaping ammonia can easily drift away without harming the occupants. As the refrigerant gets compressed under high pressure and temperature inside the compressor, it must not cause any explosion or catch fire within the system and continue its non-flammable properties. Fluid to Gas expansion is low. High suction gas density at the compressor suction means low sized compressor and a lesser-powered compressor motor. Details. R12 condenses at a moderate pressure under normal atmospheric temperature, has a boiling point of -29°C. The R410A Properties: This refrigerant is commonly known as Puron and it is hydro fluorocarbon.

Please note that not all products are available in all markets. In fact, it can absorb vapor as quickly as a compressor. Between the refrigerant R410a and R600a PK. It requires an expensive piping system to handle high condensing pressure. 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. They provide: - a basic equation for each refrigerant (only for R134a, R22, R123, R717, R14) - tables on: saturated states, superheated vapour, physical properties of the refrigerant - a diagram of the refrigerant. Liquide Vapeur Liquide Vapeur Liquide Vapeur Liquide Vapeur Temperature Pression Pression Densité Densité Enthalpie Enthalpie Entropie Entropie (°C) (bar abs) (bar abs) (Kg/M 3 This happens only when the refrigerant temperature reaches beyond its critical temperature, ie. 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. In Australia R410A is a popular product for commercial and residential air conditioning systems as an alternative to R22. 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. To find longer-term alternatives, it is necessary to move to R32 HFO blends or R717, all of which require significant system re-design. This non chlorine based refrigerant that has replaced R-22 in air conditioning systems. Repeated dose toxicity An electronic detector for such refrigerant leaks is presently available. The cooling process takes place by circulating the same cold air within the refrigerator space, as the temperature of the re-circulated air drops down; the expansion valve throttles the flow of the refrigerant. In case of a repair, maintenance or accidental leakage; refrigerant must be readily available at a reasonable price. HFCs (Hydro Fluoro Carbons). R32 is a possible longer-term alternative. Research says that the erratic launch of rockets causes a much greater depletion of the ozone layer than CFC. Moisture can enter into the system while charging of refrigerant, while repair ie. It should not freeze during application. r22 was completely phased out due to its high ozone depleting potential (ODP) = 0.05 and Global Warming Potential (GWP) = 1100. It gives a low refrigeration effect. The refrigerating effect per pound for R12 is comparatively low as compared to other refrigerants. R32 refrigerant is the short name for CH2F2(difluoromethane). all these properties make R32 a promising choice for the present. Lower condenser pressure reduces the power drawn by the compressor during compression thereby giving a smaller sized compressor. Here are some of the desirable properties of refrigerant explained in detail. It has properties close to those of R22, and for this reason, has been extensively used in Europe.
