| Abstract: | An irreversible cycle model of ferroelectric Ericsson refrigerators is established,in which the influence of finite heat capacities of external reservoirs,heat resistance,inherent regenerative losses,additional regenerative losses and irreversibility inside the working substances are taken into account.By using the method of finite-time thermodynamics,the optimal equations between the cooling rate and coefficient of performance and between the cooling rate and the power input are derived.Moreover,the maximu... |
