why r134a is used as refrigerant

The third reason is a little more obscure. The alternative to R12 is currently R134a widely used in automobiles. As a natural gas in the earth's biosphere, CO2 has the lowest ODP . Today's refrigerant alternatives are more complex to manufacture and come at a high price. r-134a (1,1,1,2-tetrafluoroethane) is a kind of non-chlorine atom, does not damage the ozone layer, and has good performance (non-flammable, non-explosive, non-toxic, non-irritating, non-corrosive) refrigerant, its cooling capacity and efficiency are very close to r-12 (dichlorodifluoromethane, freon), so it is regarded as a good long-term With the r134a self sealing adapter, this refrigerator freon recharge kit can compitable with not only piercing r134a cans but also self sealing cans. my country has stopped the production of using R12 as a refrigerant. Its a matter of the properties of the refrigerant. Why Use CO2 as a Refrigerant? The core benefit of R1234yf- and primary reason for the switch too- is that it's vastly better for the environment. It is quite close to the dichlorodifluoromethane/R-12 refrigerant. Various refrigerators manufactured after 1995 typically use the R134a refrigerant. Application This recharge refrigerator kit usually used for home air condition refrigerant systems with R-134a R-12 R-22 types freon. While R-134a does not have an Ozone Depletion Potential it does have a high Global Warming Potential. This will mainly affect the use of: HFC 134a as a refrigerant. SAE J3030, a new standard for RRR both R-134a and R-1234yf with a single machine when the two refrigerants that are in simultaneous use. Is 134a refrigerant banned? R-134a came about as a replacement refrigerant for the R-12 Refrigerant that was being phased out due to the Chlorine that it contained. Currently it is also being widely used in the air conditioning system in newer automotive vehicles. Comfort cooling is high temperature refrigeration application whereas R-12 and R-134A are medium temperature refrigeration refrigerants. It is safe for normal handling as it is non-toxic, non-flammable and non-corrosive. The gas cooler rejects heat from the refrigerant at higher pressures than those generated in an R-134a system, has better heat transfer, and allows for higher velocities of refrigerant flow. The sun's ultraviolet rays directly irradiate the earth, causing harm to plants and animals. As a result, refrigerants like R410A and R134a can only be used as an alternative working medium and should not be used for a long time. The sales restriction covers refrigerants contained in cylinders, cans, or drums, except for the sale of small cans of substitute refrigerants (e.g., R-134a for use in motor vehicle air conditioners). The boiling point of R134a at atmospheric pressure is -26.9C, and the boiling point of R134a is -10.6C at a . If you drive a hybrid or electric car, see your dealership for A/C recharges. R-134a is economical. R-134a is also used in quite a few refrigerant blends as well as a key ingredient. An initial group of new A/C-related SAE standards was developed They are SAE J2843, which covers recovery, recycling and recharging (RRR) equipment for flammable refrigerants. About 95 percent of a chiller's lifetime carbon footprint comes from these indirect emissions. See, the reason we started using R134a is because its predecessor, R12 aka "freon" was in fact horrible for the environment and the Ozone layer, due to release chlorine gas into the atmosphere. So we switched to R134a, but . The main purpose: R-134a is the most widely used medium and low temperature environmentally friendly refrigerant. The R134a is a well-known refrigerant that is used in different air conditioning and refrigeration units. It's the lubricant in R-134a that causes the issue in Hybrid and Electric vehicles. R-12 was the standard refrigerant for vehicles for many years but as air conditioning became more and more popular the amount of R-12 Refrigerant that was released into the atmosphere grew and grew. R134a refrigerant gas has a little possibility of depletion of ozone and less than 100 years global warming. 134a is or was considered the safe refigerant also has a bit to do with the price of the gas, 134a has little risk on accadentally inhaling it from a leak or service while r404a is potentually deadly on accadental inhalation having 404a in a building isnt smart while 134a is a safe route. Maximize to your needs as much as possible It is now being used as a replacement for R-12 CFC refrigerant in the area of centrifugal, rotary screw, scroll and reciprocating compresssors. It has top thermal stability, critical temperature, non-toxic, non-flammable, and noncorrosive advantages which is the reason people use this R134a refrigerant widely. This sales restriction does not cover refrigeration and air-conditioning equipment or components containing refrigerants. Due to the good comprehensive performance of HFC-134a, it becomes a very effective and safe alternative to CFC-12. Some of these include: R-416A, R-420A, R-423A. All F gases with global warming potentials of more than 150 will be banned as the refrigerant or foam blowing agent in any hermetically sealed system. In comparison to traditional refrigerators, R134a works well in medium as well as high-temperature environments. They are being quoted at several times the cost of R-134a and are forecast to remain more expensive than R-134a is today, even at full . (GWP) The higher a GWP number the more damage the product can do towards Global Warming. im not a genious this is just why i think its the correct There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a and R-744. R-134A is a replacement for R-12 and has less ozone depletion potential than the formerly very widely used R-12. Most hybrid and All electric cars have an electric a/c compressor that use a different oil than that used with replacement R-134a sold at retail. As a natural refrigerant, CO2 has many advantages over other substances, such as: Low kinematic viscosity; .
