Title conditioning reliability analysis and maintenance outline design

Abstract

With the improvement of people's living standards, more and more families and businesses are using air conditionings. It has become a necessary device in people’s life. But the performance of air conditioning still has many problems, which need to be improved to meet people's needs.

This paper has analyzed the structure and reliability of air conditioning system and build up the reliability model. Then analysis the faults, build up the fault trees, and draw up the air condition fault rating index. This paper describes the application of reliability analysis software CARMES, which can make the system more comprehensive and effective to analyze the reliability of the system. A reasonable and feasible maintenance and repair strategy is developed, which can help to improve the maintenance of air conditioning system and help to improve the performance of the air conditioning system.

Keywords: air conditioner reliability analysis failure mode fault analysis Maintenance outline CARMES application
