What is the formula for finding COP?
The formula for Coefficient of performance for a refrigerator/Air conditioning is (Temperature of evaporator) /(Temperature of heat sink – temperature of evaporator). So, to increase COP for a given evaporator temperature you would have to decrease the temperature of the heat sink (condenser).
How do you find the coefficient of performance of a Carnot refrigerator?
The coefficient of performance of the fridge is the refrigerating effect per cycle, Q1, divided by the net work done on the fridge per cycle, and, for a Carnot cycle it can be calculated from T1/(T2 − T1).
What is COP in Carnot cycle?
4.1. The coefficient of performance (COP) of the heat pump is defined as the ratio of the amount of heat provided to the required work. The COP is typically greater than 1, which means that heat pumps consume less energy than electric heaters when providing the same amount of heat.
What is COP of refrigerator?
The coefficient of performance, COP, of a refrigerator is defined as the heat removed from the cold reservoir Qcold (i.e., inside a refrigerator) divided by the work W done to remove the heat (i.e., the work done by the compressor).
What is the formula of coefficient of performance?
Coefficient of Performance: This coefficient of performance (COP) calculator calculates the ratio of heating or cooling provided to work required. The most basic formula to COP is Q/W, where Q is the heat supplied to or removed from the reservoir and W is the work done by the heat pump.
What is the COP of a Carnot refrigerator operating between C and 25 C?
4.5
A Carnot refrigerator operates in a room in which the temperature is 25 degrees C. The refrigerator consumes 500 W of power when operating and has a COP of 4.5.
How is police compressor calculated?
Cooling Load – Convert between kW/ton to COP or EER
- kW/ton = 12 / EER.
- kW/ton = 12 / (COP x 3.412)
- COP = EER / 3.412.
- COP = 12 / (kW/ton) / 3.412.
- EER = 12 / (kW/ton)
- EER = COP x 3.412.
How is police domestic fridge calculated?
Actual COP is defined as amount of heat absorbed by unit mass of refrigerant in the Evaporator. Q act = V * I Work of compression is defined as the amount of refrigeration occurred in Evaporator, required to compressor work.
How do you find a COP on a refrigerator?
For a refrigerator the coefficient of performance is COP = Qlow/(-W). Details of the calculation: (a) COP = Qlow/(-W). (-W) = Qlow/COP = 120/5 J = 24 J.
What is COP value?
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.
