This paper presents a method for the calculation of different reliability parameters of a multi-state refrigeration system, such as system's mean failure rate and mean time to failure (MTTF), asymptotic system failure rate and asymptotic MTTF, where the system and its components can have different performance levels ranging from perfect functioning to complete failure. The suggested approach is based on Equivalent Parameter Model, developed for the Multi-State System. Corresponding procedures are suggested. A numerical example is presented in order to illustrate the approach.
