【摘要】：制冷空调技术被广泛应用于工业、商业、医疗卫生等各个领域，已经渗透到人们的日常生活中。随着空调种类、数量的增加，空调发生功能故障的诱发因素越来越多，空调一旦发生故障，不仅给用户带来不便，而且影响设备生产企业的形象。在当下激烈的市场竞争下，各大空调企业开始重视空调设备售后维修服务，提高设备可靠性，从而增强自身的竞争力。以可靠性为中心的维修（RCM）合理利用维修资源，消耗最少的资源维持设备固有的可靠性、安全性，将该理论应用于设备维修管理的工作一直在探索中进行，但在空调领域的研究仍为空白，是亟待展开的研究工作。本文对以可靠性为中心的维修理论进行了深入研究，并在该理论的基础上，结合空调系统的特点引入了风险分析法，对空调设备可靠性的几种影响因素进行半定量化分析，提出了适合空调设备维修的RCM分析方法，并以南昌某家居城中央空调系统为例，对其进行系统划分、设备重要度分析、故障模式及影响分析，最终为该空调系统中的各设备制定出正确的维修管理策略。为了提高RCM分析的效率，确保分析过程的准确性，本文以VC++作为开发工具，Access作为后台数据库，开发一套基于RCM的空调设备维修管理系统，在管理系统的故障数据库中收集了大量的空调设备故障信息，作为RCM分析的依据。运用该管理系统可以对空调设备进行RCM分析，决策得到适合的维修策略，，提高了分析效率，科学地指导维修人员的空调维修工作。
[Abstract]:Refrigeration and air conditioning technology has been widely used in industrial, commercial, medical and health fields, and has penetrated into people's daily life. With the increase of the type and quantity of air conditioning, there are more and more inducing factors of air conditioning failure. Once the air conditioning failure occurs, it will not only bring inconvenience to the users, but also affect the image of the equipment production enterprises. In the current fierce market competition, the major air conditioning enterprises began to attach importance to air conditioning equipment after-sales maintenance services, improve equipment reliability, thereby enhancing their competitiveness. The maintenance (RCM), which takes reliability as the center, makes rational use of maintenance resources, and consumes the least resources to maintain the inherent reliability and safety of the equipment. The application of this theory to the maintenance management of equipment has been in the process of exploration. However, the research in the field of air-conditioning is still blank, is the urgent work to be carried out. In this paper, the reliability centered maintenance theory is deeply studied, and on the basis of this theory, risk analysis method is introduced in combination with the characteristics of air conditioning system, and several factors affecting the reliability of air conditioning equipment are semi-quantitatively analyzed. The RCM analysis method suitable for air conditioning equipment maintenance is put forward. Taking a central air conditioning system in Nanchang City as an example, the system division, equipment importance analysis, failure mode and influence analysis are carried out. Finally, the correct maintenance management strategy is worked out for each equipment in the air conditioning system. In order to improve the efficiency of RCM analysis and ensure the accuracy of the analysis process, a maintenance and management system of air conditioning equipment based on RCM is developed with VC as the development tool and access as the backstage database. A large amount of fault information of air conditioning equipment is collected in the fault database of management system as the basis of RCM analysis. This management system can be used for RCM analysis of air conditioning equipment, and the appropriate maintenance strategy can be obtained. The efficiency of analysis is improved and the maintenance work of air conditioning personnel is scientifically guided.
