Which is better R600a vs R134a?
R600a is a flammable gas and has low Global Warming Potential (GWP) and Ozone Depletion Potential (ODP) comparing to high GWP of R134a. also refrigeration cycle working with R600a thanks to producing the same temperature by having a lower pressure in condenser has a higher efficiency.
Which is better R290 or R134a?
Compared to R22 and R134a, R290 results in a 40% reduction in refrigerant charge. R600a results in a 45% reduction in charge compared to R134a, and a 60% reduction compared to R12.
Which gas is better R32 or R410A?
While there are many reasons for this switch, the main benefits of R32 are: R32 has a GWP of 675, roughly 30% lower than that of R410A. R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate. Ozone Depletion Potential of 0.
Which refrigerant is generally used in fridge?
HFC-134a (1,1,1,2-Tetrafluoroethane) is one of the commonly used refrigerant gases which you can find in almost all the present time refrigerators.
Which fridge is most energy efficient?

Can I replace R134a with R290?
R290 is also an excellent alternative to hydroflurocarbon (HFC) refrigerants R134a (used in refrigerators) and R404a (used in freezers).
What can I replace R290 with?
The specialist for hydrocarbon refrigerant has released the Minus40 brand as an ideal replacement for CFCs and HCFCs. It is already being used in supermarket food display cabinets, ice-cream display cabinets, heat pumps, and air conditioning systems.
Why ammonia is not used in domestic refrigerator?
Pure ammonia gas is highly toxic to people and would pose a threat if the refrigerator were to leak, so all home refrigerators dont use pure ammonia.

Are modern fridges more efficient?
Its certainly true that modern refrigerators are staggeringly more efficient than models produced in the 1970s and 80s—in some cases by up to 75 percent. The Energy Star requirements that go into effect this week stipulate that a 28-cubic-foot fridge may not exceed 403.82 kWh per year.

Can I use r134 instead of R290?
R290 is also an excellent alternative to hydroflurocarbon (HFC) refrigerants R134a (used in refrigerators) and R404a (used in freezers). Using this refrigerant can also reduce overall energy costs by up to 28%.
Which is more flammable R32 or R410A?
Flammability of R32 has 80% burning velocity less than R290 and slightly flammable when compare with R410A. Although, R32 discharge gas temperature is higher than R410A around 20Â°C and this can damage compressors motor at some heat pump condition especially at high compression zone.
