Can COP of heat pump be less than 1?
The COP of the refrigerator and air-conditioner can be less than one or greater than one. The above formula also shows that the COP of the heat pump can never be less than one; it is always more than one.
What does COP mean for heat pumps?
Coefficient of Performance
What is a good cop rating for a heat pump?
A good COP for heat pump units starts at about 2.0 for an air source heat pump and about 3.1 for geothermal, but heat pump COP can be well above 4.0 too, as seen in the chart below.
What is the value of COP of heat pump?
The COP of a geothermal heat pump is the ratio of the heating or cooling output to the energy input to run the machine. A high COP over 1.0 means your heat pump is performing very efficiently, and your heating bills will be low. A heat pump is the only heating and cooling device that has a COP over 1.0.
Can COPs be less than1?
The coefficient of performance (COP) of refrigeration is always more than 1. Hence option (a) is correct. COP is the ratio of heat extracted from the refrigerator to the work done on the refrigerant. Thus it is but obvious that the value of COP is bound to be greater than unity since efficiency is always less than 1.
How do you find a real cop?
You can calculate the coefficient of performance by dividing how much energy a system produces by the amount of energy you input into the system.
How can cop be greater than 1?
The COP usually exceeds 1, especially in heat pumps, because, instead of just converting work to heat (which, if 100% efficient, would be a COP of 1), it pumps additional heat from a heat source to where the heat is required. Less work is required to move heat than for conversion into heat.
