heat pump performance coefficient
measures the amount of heat supplied per unit of input work.
symbols, variables and units
Q_H,W: energy in the same period (J); COP_H: dimensionless.
applicable conditions and boundaries
needs to clarify the system boundaries, working conditions and auxiliary energy consumption; it is not the thermal engine efficiency.
