What is the COP of a heat pump?

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. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.

What is the COP of an air to air heat pump?

Heat Pump COP (Coeffient Of Performance) is defined by the ratio of the output power to the input power. This coefficient is useful when you select a suitable air to air heat pump system for your house or office. By looking at the COP, you can tell how efficient the equipment is.

What is coefficient of performance (COP) of a heat pump?

COP or Coefficient Of Performance is the most basic energy-efficiency metric of any heat engine. It’s instrumental when comparing heat pumps, fridges, and air conditioners. Definition: COP is the ratio of how much useful heat (or cold) a heat pump will produce if we give it certain energy input.

What is the COP of an electric heater?

Therefore the COP of the electric heater is = 10W/10W = 1:1 In heat pump system, the heat from the outside of the house is transferred to the inside of the room by vapor compression cycle. Energy is used to move the outdoor heat to the room.

What is the highest cop a heat pump can achieve?

In fact, the highest COP a heat pump can achieve is about 4.5. Any heat pump with a COP of above 3 has a very high energy efficiency. Here is a graph of how much more efficient high COP heat pumps are. We put the COP 2 as zero and calculated by how many percent more efficient the higher COP heat pumps are.
