Air conditioning systems generally have moving parts, so an understanding of their reliability is important in system maintenance. Most university buildings have very many air conditioning systems that are often managed by a single maintenance department, so it is necessary to obtain an overall grasp of air conditioning system reliability for the entire university. We report here results obtained by analyzing reliability and maintainability concerning the introduction of gas heat pump (GHP) air conditioners to university facilities. We used a Weibull distribution to analyze the GHP failure time and a lognormal distribution to analyze the maintenance time for the GHP. From the value of the shape parameter obtained in the Weibull analysis, we determined that the GHP failure rate was rising but can be said to be nearly constant. It is estimated that major maintenance in which the maintenance time is 6 hours or more differs from a failure of 6 hours or less. Additionally, the reliability and maintainability analysis was performed separately for all of the field data, each department, the maintenance time, major maintenance, and various maintenance measures.
