It is not.
"A typical 40°F(4°C) cooler's condensing unit might have a COP (Coefficient of Performance) of 2.5"
"A 0°F (-14°C) freezer's COP is more likely to be about 1.67"

What does the Q represent in the COP equation for a refrigerator?
It repressents the Heat Transfer rate, in kW, Btu/hour etc...
How do you increase the COP of a Carnot refrigerator or heat pump?
Decrease temperature difference between cold coolant and hot coolant
Why COP actual lower than COP theoretical?
Theoretical calculations take into account many factors that in fact should not be involved
How subcooling increase the COP of vapour compression refrigeration?
The sub-cooling or under-cooling in the saturated liquid line increases the refrigeration effect or cooling effect, thus the COP of VCR system increases.
Why COP is used for evaluation of compression refrigeration system but not absorption refrigeration system?
cause its a gas
Is cop of refrigerator must be greater than 1?
Yes, C.O.P is always greater than 1 in case of refrigeration system and heat pump. but in case of aircraft engines C.O.P is less than 1. because in high altitudes the air pressure is always low. so the C.O.P becomes less than 1 in most cases..
What will be the COP of a domestic refrigerator available in the market?
1
What is the Typical value of cop of refrigerator?
there are many factors affecting COP. maybe it ranges from 2.5-5
What is a good cop of a refrigerator?
ONE that is Near the COP_R of the coeff for the carnot cycle
What does COP stand for from a thermodynamic stand point?
COP in thermodynamics usually refers to the Coefficient Of Performance(sometimes CP) andis the ratio of the heating or cooling provided over the electrical energy consumed.COPheating = |QH|/W = (|QC| + W)/WCOPcooling = |QC|/WwhereQC is the heat removed from the cold reservoirQH is the heat supplied by the hot reservoirThe COP provides a measure of performance for heat pumps that is analogous to thermal efficiency for power cycles. In the case of a refrigerator, the cold reservoir is the air in the room around the refrigerator and the hot reservoir is the interior of the refrigerator - counterintuitive as that may sound. In the case of the refrigerator, the refrigerant is compressed such that it is hotter than the room, thus making it a source of heat. Part of the energy comes from the interior of the refrigerator (QC) and the rest from the work done by the compressor. When a heat pump is used to warm a building, the outside air is the hot reservoir - even though it may be colder than inside the building. Once again, the fluid used in the heat pump is compressed so that it can dump heat into the building and then when expanded outside, it is cold enough to absorb energy from the outside air.

Does domestic refrigerator have more cop than air conditioner?
COP of any refrigerating system mainly depends on the performance of the compressors used and the heat load at the evaporator. A similar or almost equal COP can be achieved from any system by varying its working parameters like load, kind of refrigerant used and the system working pressure.

How do you increase the COP of a Carnot refrigerator or heat pump?
Decrease temperature difference between cold coolant and hot coolant
What is the difference between cofficient of performance and efficiency?
The COP can be more that one since the heat transferred can be more than power required by the refrigerator but the efficiency can never be more than one since the power generated by engine cannot be more than the total heat content of the fuel.
Is a police stronger than a cop?
no a police is weaker than a cop because it solves more cases and it is brave
In Lady Gaga love game what is she doing with the cop?
They're making out.
Why actual cop of vapour compression refrigeration is less than theoretical cop?
