Projeto de implementação do PMOC - Plano de manutenção, operação e controle nos ar condicionadores em uma instituição de ensino superior

Abstract

The proper maintenance of air conditioning systems is essential to ensure thermal comfort in a variety of environments, including homes, businesses, and schools. Conversely, the lack of adequate maintenance can lead to negative consequences for the user’s health, especially regarding respiratory function. It can also result in reduced performance and reliability of systems/equipment and high energy consumption. In this sense, this arti cle aims to present a proposal for the design of an Operation and Control Maintenance Plan (OCMP) in a higher education institution, where the DMAIC methodology (Define, Measure, Analyze, Improve, and Control) is applied to manage the maintenance of air conditioning systems and ensure a safe and healthy environment for users. To achieve this goal, the project establishes specific objectives, such as analyzing the current situation of the institute in advance, identifying and mapping all air conditioning equipment in the environment, and defining preventive and corrective maintenance procedures for the equipment. This information was used to identify the main problems in the maintenance sector through quality tools such as the "5W"technique (five whys) and the cause-and effect matrix. Based on this data, an action plan called 5W2H (5 Why and 2 How) was developed, associated with the GUT prioritization matrix (Gravity, Urgency, and Ten dency) to describe measures to resolve the most recurring inconsistencies in the sector and, finally, the creation of an OCMP project.The aforementioned research not only pro vides a solution to the air conditioning equipment maintenance problem but also has socioeconomic and environmental relevance. The research provides a diagnosis of reality, prognosis through instruments such as the 5W2H plan and the Operation and Control Maintenance Plan (OCMP) to maximize efficiency and continuous improvement of the institute’s maintenance processes. The testing and validation of the use of the SIGMA software applied to the OCMP confirmed its potential as a relevant tool to assist the higher education institution in improving the management of air conditioning system mainte nance. Finally, the implementation of the instructions and guidelines contained in this research is essential to comply with legal regulations and ensure a healthy environment, thermal comfort, improved productivity, and contribution to sustainability.
