Abstract

The invention discloses a method for evaluating the reliability of a wall-mounted air-conditioning system. The steps include: analyzing the structure-function relationship of the air-conditioning system; establishing a reliability function block diagram model of the air-conditioning system step by step; establishing a mathematical model of the reliability of the air-conditioning system ; Establish evaluation procedures. The present invention establishes the functional relationship between the reliability of parts or components, parts, assemblies, units, subsystems and systems, making it possible to carry out reliability prediction and distribution in the design and development process of air conditioning systems, and can also be used for prediction The changing trend of the reliability of the air-conditioning system after installation and use, the probability of possible failure and the maintenance cost are estimated, so as to formulate a scientific after-sales maintenance strategy.

Description

technical field [0001] The invention relates to an air-conditioning system evaluation technology, which is suitable for analyzing and evaluating the reliability level of the wall-mounted air conditioner during the design and use process, and particularly relates to a method for evaluating the reliability of the wall-mounted air conditioner system. Background technique [0002] The reliability model of the air conditioner adjustment system is used in the demonstration, design, manufacture and use of air conditioner products, and the wall-mounted air conditioner is the most widely used type of air conditioner product. [0003] Reliability index is the core index to reflect the quality of air conditioners. Objectively and accurately assessing the reliability level of air conditioners has become a basic technical work for enterprises, and has also attracted widespread attention from consumers. At present, the evaluation of air conditioner reliability at home and abroad mainly us...
