Hello readers welcome to the new post. Here we will learn R407C Pressure-Temperature Chart. R410 refrigerant is a very famous refrigerant solution used for air conditioning systems. It is a mixture of hydrofluorocarbons and is employed as a refrigerant. it is an azeotropic blend of difluoromethane (R-32), pentafluoroethane (R-125), and 1,1,1,2-tetrafluoromethane (R-134a). Difluoromethane is used to offer heat capacity, pentafluoroethane reduces flammability, and tetrafluoromethane reduces pressure.R-407C cylinders are colored burnt orange. Here we will make an R407C Pressure-Temperature Chart. let’s get started with 407c-p-t-chart.

What is R407C refrigerant used for?
407C refrigerant operates like the HCFC 22 in evaporator temperatue range from –7 to 10 °C (20 to 50 °F).It is made to use for new instruments and service refrigerant for existing HCFC-22 air conditioning, heat pump, and medium temperature refrigeration equipment.
Is R407C refrigerant banned?
Many refrigerants like R134a, R410A, and R407C, have been banned since January 1, 2024 in the USA
Is 407C refrigerant compatible with R22?
R-407C is used for systems that use R22. it must not mixed with R22 or any other refrigerant
What is the difference between R22 and 407C?
R407C comes with thermodynamic features that make it like to use as a replacement for R22. with the same compressor capacitors and system pressure and temperature that are alike. The main difference between R407C is that it has a temperature glide of 6°C (1 0.8°F) for AC evaporating temperatures.
Is R407C better than R22?
it is found that R22 works well than R407C in many featues. COP, cooling capacity Energy Consumption, and energetic analysis but the retrofitting aspect is the best refrigerant and R410A is suitable for the new design.
Is R407C harmful?
It is a non-flammable material. Overexposure can cause dizziness and concentration loss. For high levels, CNS depression and cardiac arrhythmia can be caused by exposure. Vapors displace air and can cause asphyxiation in closed spaces.
What are the disadvantages of R407C refrigerant?
The main disadvantage of R407C is a glide of 10°F. since R407c is a zeotropic mixture glide is the temperatue difference between 3 substances boiling points. If 10 degrees is not very high it has a high impact on different components of the system.
What is the efficiency of 407C?
The EER was found by dividing cooling capacity with shaft power input to the compressor plus indoor and outdoor fan power. R-407C had an EER that had a range 5. 7% to 11% lower than R-22.
Is R134a better than R407C?
R407C is high pressure refrigerant that R134a. provides a good coefficient of working in tightly sealed systems. Thermo king instrument is made for effective working with high pressure refrigerant and has done with R407C for more than 10 years
How much pressure is 407C compared to R22?
The R407C head pressure trend is about 11 percent higher than the R22 head pressure. R407C suction pressure trends are about 11-12% lower than R-22 suction pressure.
What is the maximum pressure for R407C?
R407C unit operates at a higher temperatue than R22 and needs high-pressure switches for working at a high cut-out pressure value of about 450 psig.
Why is the R-22 expensive?
R22 refrigerant is high value since there is a limited supply of it. It is ozone-depleting material and harmful to the environment.
What is the difference between 407C and MO99?
The main difference is that pure HFC fluids such as R407C need a complete change out of mineral oil to POE lubricant for the R22/MO system and Freon MO99 is formulated to be used without the need for oil change out that saves cost and time.
Which AC gas is better R32 or R22?
The lower GWP of R32 defines that it has a low impact on the environment as compared to R22 and R410A. R32 has a higher energy efficiency then R22 and R410A which means AC unit systems using R32 need less energy to work and casues low curent use and cost.
