What is r407a refrigerant?
R-407A is a mixture of gasses used as a refrigerant. It is a zeotropic blend of difluoromethane (HFC-32), pentafluoroethane (HFC-125) and 1,1,1,2-tetrafluoroethane (HFC-134a).
Can R407A replace R22?
R407A is a HFC blend, used as a replacement for R22 and R404A in low and medium temperature supermarket applications. Due to its moderate Global Warming Potential (GWP) it is also considered as an interim replacement for R404A and R507 in existing and new applications.
What is R407A used for?
Refrigerant R407A is commonly used in low and medium temperature refrigeration applications. It has earlier been used as a substitute for R22, for example. R407A is an excellent and energy-efficient low-GWP gas suitable for many R404A systems. Energy savings of up to 10% have been reported in many systems.
What type of refrigerant is 407C?
R-407C
Product summary. R-407C is a non-azeotropic mixed refrigerant composed of the three ingredients R-32, R-125, and R-134a, and was developed as a substitute refrigerant for R-22, used in applications such as air conditioning equipment and chiller equipment for medium temperature ranges.
Can you mix R-22 with 407C?
Mixing R22 with R407C According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.
What is the best replacement freon for R22?
R-407c
The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.
How do you charge a 407C?
As with any other refrigerant blend, when charging equipment with Freon™ 407C, remove liquid refrigerant from the cylinder to charge the unit. Returnable cylinders containing Freon™ 407C are equipped with liquid and vapor valves.
Can you still use R-407C?
The production of refrigerants R134a, R407C, R407F and R410A is being phased out step-by-step. As there is no usage ban for this group of refrigerants, installations running on R134a, R407C, R407F and R410A may still be refilled after 2030.
What pressure should 407C run at?
If this is so always evaporating above zero, 4 or 5 deg celcius, R407c will have a low pressure (suction ) of about 50 psi. and a high pressure ( discharge ) of about 280 psi, which is about 55 deg celcius, cooling cycle.
Is R22 still used?
The U.S. government has placed restrictions on R22 and has issued the requirement that R22 refrigerant must be eliminated from use in cooling systems by the year 2020. At this point, R22 will no longer be manufactured and cannot be used as a refrigerant in new air conditioning systems.
