Generalized Performance Characteristics of Refrigeration and Heat Pump Systems

Figure 9

Dimensionless cooling rate ( 𝑟 ) versus coefficient of performance ( 𝑤 ) for the generic model designed to describe the behavior of real refrigeration systems in finite time. The assumed sources of loss are: Finite heat transfer rates, heat leak, and friction. Plots are presented for different values of friction while heat leak is kept constant at 𝜅 𝐿 = 0 . 1 .
