Can a refrigerator have a coefficient of performance greater than 1?

As mentioned in all answers, generally conventional refrigeration systems (vapor compression) have a COP greater than 1, which explains their use. However, non conventional refrigeration systems (Absorption, vortex tube, air refrigeration systems) may have generally a COP less than 1 which limits their use.

What is the formula of coefficient of performance?

Dividing heat extracted from the evaporator by the work done by the compressor gives you the coefficient of performance for the refrigerator. You can also divide the heat transferred from the condenser by the work done by the compressor to get the heat pump’s coefficient of performance.

Can coefficient of performance be greater than 1?

COP of refriegeration is always greater than one. The coefficient of performance (COP) of refrigeration is always more than 1. COP is the ratio of heat extracted from the refrigerator to the work done on the refrigerant. It is also called by the name Theoretical coefficient of performance.

How can coefficient of performance be improved?

compression cycle. To improve the coefficient of performance, its requires that the compressor work should decrease and refrigeration effect should increase. It means that decrease in condenser pressure and temperature so the refrigeration effect will increase and compressor input work due to this cop will increase.

Which one is not eco friendly refrigerant?

Chlorofluorocarbons (CFCs): Due to their high ODP (Ozone Depletion Potential) and high GWP (Global Warming Potential), they are considered non-eco-friendly refrigerant gases.

What is the most environmentally friendly refrigerant?

The most environmentally friendly refrigerants are hydrofluorocarbons (HFC) and hydrofluoro-olefins (HFO). HFCs are comprised of fluorinated hydrocarbons. While HFCs can contribute to global warming, they do not affect the ozone layer directly.

What is replacing R-410A?

The leading replacement for R-410A refrigerant is a pure, single component refrigerant called R-32, which has one-third the global warming potential of R‑410A. Some products with this next generation refrigerant have already been introduced in the United States.

What’s the difference between R410A and R32?

R32 Infographic Carbon has a GWP of 1. R410A has a GWP of 2,088 meaning that if one kilogram is released into the atmosphere it would have 2,088 times the harmful effect of one kilogram of carbon. That is why we are now seeing a move to a new refrigerant – R32, which has a GWP of 675 (two-thirds less than R410a).
