Reliability analysis of central air conditioning systems

Based on the reliability theory and the function analysis of central air conditioning systems (CACS), establishes a mathematic model of the system reliability. Analysing the failure modes of each component, constructs the fault trees of both CACS and refrigeration system. Finds out the main factors causing the refrigerating system failure by the minimal cut set analysis (MCSA). Proposes the measure to improve the reliability of CACS.
