Comparison chart for HFC and HFO replacement refrigerants.

Jain et al. (6) have reported with extensive thermodynamic analysis of R407C and other alternatives in comparison to R22 have concluded from that R407C is a potential HFC refrigerant replacement.

R22 (Refrigerant) replacement Was your air conditioner system installed in 2010 or earlier? If so, it probably runs on R22 refrigerant. R22 is currently being phased out of production because it contributes to ozone depletion and global warming.

Knowing the operating R22 refrigerant charge size for the system is helpful. If it is not known, weigh the entire amount of refrigerant removed. This amount can be used as a guide for the initial quantity of R448A to be charged to the system. 3. Choose Compressor Lubricant In most instances, the lubricant in use with R22 is not suitable for use with R448A and a change to a synthetic lubricant.

RS-44b (R453a) is the newest R22 drop-in replacement refrigerant in the U.S. market. RS-44b has been sold worldwide for the past 5 years, branded as RS-70 outside the US. It is the closest replacement to R22 that operates with very similar discharge pressure, cooling capacity and flow rate as R22. It requires no oil or system component changes.

Although a replacement for CFCs has been found, the search for good alternatives for HCFCs especially R-22 is still on. 2. Literature Survey Major investigations in the area of alternate refrigerants are reviewed below from the point of view of their ability to match the performance of the widely used R22 refrigerant.

Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC). This colorless gas is better known as HCFC-22, or R-22, or (CH ClF2).It is commonly used as a propellant and refrigerant.These applications are being phased out in developed countries due to the compound's ozone depletion potential (ODP) and high global warming potential (GWP), although global use of R-22.

These refrigerants are used mainly for air conditioning and substitution of R22 in many applications. R134a has a relatively low pressure and, thus, about 50% more compressor displacement is necessary, when compared to R22 and this can make a compressor more costly. Large tube components and, as consequence, increases the cost of the system.

R12 was once used in many air conditioning units as a refrigerant or cooling agent. However, it was found to be a very bad gas for the environment. But R22 is almost equally damaging. Rules governing changing from the former to the latter differ between countries. R12 and R22 are both now banned by.

Refrigerant R12 or Freon 12 is said to be the most widely used of all the refrigerants being used for different applications. The chemical name of refrigerant R12 is dichlorodifluoromethane and its chemical formula is CCl2F2. This articles describes the properties, advantages, and disadvantages of refrigerant R-12. Unfortunately it is the CFC and it has unusually high potential to cause the.

Refrigerant R134a and refrigerant R22 in use has the following difference and features:. 1, R134a in the thermal conductivity than that of R22 fell by 10%, so R134a of the unit heat exchanger heat transfer area need to be more big. 2, R134a HFCs refrigerant and its special lipid oil prices are higher than that of R22, the operation of the equipment maintenance cost is higher.

What is the difference between R404A and refrigerant R507? The refrigerant is the blood of the refrigeration system. It is called snow, refrigerant or freon in many places. It is a working substance that continuously circulates in a refrigeration system and undergoes its own state change to achieve refrigeration. The.

If you believe your air conditioning system uses R22 refrigerant or may have been installed before 2004, call us on 0141 773 3355. R22 Replacement Benefits. The R22 Phase Out is an opportunity to replace an ageing and inefficient air conditioning system. Air conditioning systems installed before 2004 are approaching the end of their usable.
