coefficient of performance

The reason for not using the term 'efficiency' is that the coefficient of performance can often be greater than 100%.

A reasonable way to analyse these systems is by measuring their coefficient of performance.

Could you please clairfy - by system efficiency, do you mean coefficient of performance?

In heating mode, the coefficient of performance is the ratio of heat provided to the energy used by the unit.

Their efficiency is measured by a coefficient of performance (COP).

For Carnot power cycles the coefficient of performance for a heat pump is:

Not as efficient, in terms of coefficient of performance, as vapor-compression systems (see below)

The term coefficient of performance (COP) is used to describe the ratio of useful heat movement to work input.

The coefficient of performance (COP) of the underground heat exchanger thus designed was poor ranging from 1.5-3.

Compared to conventional heat pumps, Stirling heat pumps often have a higher coefficient of performance .

The coefficient of performance (COP), a more universal dimensionless measure of efficiency, is discussed in the following section.

The efficiency of a refrigerator or heat pump is given by a parameter called the coefficient of performance (COP).

The 'Efficiency' of air source heat pumps is measured by the Coefficient of performance (COP).

Coefficient of performance (COP)

While not truly a unit of capacity, a refrigeration system's coefficient of performance (CoP) is very important in determining a system's overall efficiency.

As an example, assume that inside the closed system a 100 W heating element is activated, and the air conditioner has an coefficient of performance of 200%.

With a coefficient of performance (COP) of 20 to 40, this method of cooling can be ten times more efficient than conventional air conditioning.

This ratio is termed the coefficient of performance or COP and is a measured characteristic of a thermoelectric device.

Regardless, the coefficient of performance of current commercial thermoelectric refrigerators ranges from 0.3 to 0.6, one-sixth the value of traditional vapor-compression refrigerators.

An improvement in coefficient of performance (the ratio of heat output to total power consumption) to about 5:1 along with standardisation and simplified equipment could cut costs by half.

It is used instead of the coefficient of performance, which is a dimensionless ratio that is the same in any system of units as long as they are consistent.

The coefficient of performance or COP (sometimes CP) of a heat pump is the ratio of the heating or cooling provided over the electrical energy consumed.

As a heating technology, joule heating has a coefficient of performance of 1.0, meaning that every 1 watt of electrical power is converted to 1 watt of heat.

In order to do so, the air conditioner must increase its power consumption by the inverse of its "efficiency" (coefficient of performance) times the amount of power dissipated into the system.

SEER is related to the coefficient of performance (COP) commonly used in thermodynamics and also to the Energy Efficiency Ratio (EER).
