Its notable characteristics include an average boiling point of about -43.6°F (-42°C). It also has a critical temperature of 186.7°F (86.97°C) and a critical pressure of 700.49 psi (48.3 bar).

R407C also has a defining feature of temperature glide: the gradual temperature change for phase transitions between vapor and liquid and vice versa. Its temperature glide is 10°F (5-7°C). This characteristic can affect the efficiency of heat exchangers in an HVAC system, which means wonderful equipment tuning is needed to achieve the best results.

Regarding thermodynamic properties, R407C has a specific heat capacity and latent heat of vaporization roughly equal to 220 kJ/kg. In air conditioning and heat pumps, liquid R407C must achieve effective heat transfer, volumetric, and mass flow rate supposition to optimize work needs to consider a specific action to enhance its effectiveness; therefore, it also makes it feasible for use in those fields.  This also means that its density as a liquid at 25 degrees C must be roughly 1.136 g/cm cube, which might also help in system charge requirements.

Knowing these helps system engineers design and construct equipment with improved features. In conjunction with R407C properties, the efficiency of the designed apparatus is also calculated.

R407C Vapor Pressure and Boiling Point

R407C contains specific mixtures of refrigerants with vapor pressures and boiling point characteristics ideal for mid-level to high-temperature air conditioning and refrigeration systems. Its vapor pressure at 25°C is slightly under 945 kPa and 137.1 psi, making it moderately effective in a system with appropriate pressure. When compared to R410A, R407C is somewhat lower.

R407C’s boiling point is changed due to its zeotropic qualities, which deflect temperature as phase shift occurs. R407C’s temperature glide depends on unique conditions ranging from 3.9 to 5.0°C. The initial boiling point of the substance is approximately -46.7 °F (-43.7 °C ) at 1atm pressure. The glide aspect significantly impacts system design due to the alteration in hep boiling points.

R407C’s eco-friendly properties and efficiency make it the refrigerant of choice for alternates to older R22 systems and new equipment without compromising performance.

What are the Replacement Options for R407C?

R407C, a hydrofluorocarbon (HFC) blend, is widely applied in air conditioning units and refrigeration appliances; however, it is being phased out because of its high global warming potential (GWP). Suitable substitutes for R407C are other refrigerants like R32, R452B, and R454B, which have lower GWP. These substitutes are associated with better energy efficiency and lower environmental impact. It is critical to assess system component compatibility and retrofitting to maintain optimal performance and regulatory compliance when transitioning to a replacement. Always consult the refrigerant manufacturer and industry standards before replacement.

R407C as a Replacement for R-22

Because R-22 was heavily used in air conditioning and refrigeration systems, R407C has become a well-known substitute because its thermodynamic properties are relatively similar. R407C is classified as a blend of HFC (Hydrofluorocarbon). While R-22 had a GWP (Global Warming Potential) of 1810 and is currently being phased out under the Montreal Protocol, R407C possesses a more sustainable GWP of approximately 1770 refrigerating marine ecosystems. The sustainability gap between R22 and R407C shows the difference in environmental impact, with R407C having its negative impact being over 100 lower.

The significant advantage of R407C is its ability to retrofit previous R-22 systems. Minor adjustments will allow numerous systems to adapt to R407C without being replaced entirely. A potential downside with R407C is that it operates at higher pressures, necessitating Cassie compatibility evaluations on system components like compressors and seals, which are crucial for system performance. When using R407C, the system’s cooling efficiency will be lower than R-22; COP (Coefficient of Performance) is expected to drop 5 to 10% of its value.

What sets R407C apart are its glide characteristics. This unique value also contributes to the precision reliability issues of its evaporator and condenser domain. Substituting a glide of about 5-7°F (3-4°C) contributes to its appeal but works against it for systems that strive to maintain constant-temperature evaporators.

R407C does not deplete the ozone layer, thus providing compliance with environmental regulations while still serving as a dependable substitute for R-22. The best practice for sustainability and functionality is using POE (polyol ester) oil with R407C, which performs poorly with conventional mineral oils used in R-22 systems.

With the proper retrofitting procedures and following the manufacturers’ directions, transitioning to R407C allows businesses to mitigate the environmental impacts while providing effective operation of cooling and heating systems.

As affordable carbon-cutting options, these alternatives wish to implement global climate goals.

Compatibility and System Considerations: Assessing the system’s piping, compressors, and expansion valves beforehand aids in countering operational lapses, especially considering the shift to R1234yf, which tends to need retrofitting and performance modification. Consideration for the substitute refrigerant also needs to match the rest of the system devices, like heat exchangers and lubricating system components, as R32 runs at a much higher temperature than R407C.

Compliance with Guidelines: The Kigali Amendment to the Montreal Protocol and the European Union’s F-Gas Regulation mandates the phase-down of refrigerants with high global warming potential (high GWP). Industries must adopt R32 and R1234yf to meet these rigid requirements and help sustainable development. It is critical to check if the selected refrigerant meets the local and global standards.

Refrigerant Safety: Although low-GWP options are better for the environment, they come with significant risks from a safety perspective. R32 and R1234yf refrigerants are categorized A2L as mildly flammable and pose safety risks during installation, maintenance, and operation. Risk mitigation requires proper training, appropriate safety equipment, and stringent protocols during the operation.

Strategic Changes: Natural refrigerants like R290 (propane) and CO2 signify the move away from R407C. The transition alongside R32 and R1234yf indicates the direction toward environmentally friendly cooling solutions. All refrigerants have unique advantages and disadvantages, but constant technological advancements are improving their efficacy. Sustained business changes for the planned shift must approach all angles, from environmental impacts to operational and regulatory burdens, ensuring a seamless transition to modern refrigerants.
