Zusammenfassung:Refrigeration is a critical component of thermal environment engineering. The process of removing heat from a substance under precise conditions is referred to as refrigeration. It also includes the process of lowering and maintaining a body's temperature below the ambient temperature. In this paper, we examine the availability and cost function of the system of the Refrigeration plant. This system has three modes: normal, degraded, and failed. The system is divided into four sections: A (Compressor), B (Condenser), C (two standby expansion valves), and D. (three evaporators in series). A standby expansion valve is installed to improve the performance of the refrigeration plant. The supplementary variable technique is used to obtain state probabilities and the inversion process is used to obtain the expression of operational availability and profit functions. The MTTF (mean time to failure) is also estimated. A numerical example is presented with a graphical presentation to illustrate the practical advantages of the model.
