O impacto da manutenibilidade na análise de falhas em um sistema de climatização de um ambiente hospitalar

Abstract

Air conditioning systems are widely used in hospital environments, in addition to maintaining the thermal comfort of the occupants, its main objective is to establish the necessary indoor air quality standards, such as: temperature, relative humidity and CO2 level. Such parameters need to be monitored constantly, as they can directly interfere with the patient's recovery and/or worsen your clinical condition. In order to guarantee the availability and reliability of these equipments, this work aims to identify and analyze the main failure modes of these systems. To this end, we analyzed the presented failures of an HVAC system that serves an environment hospital and the maintenance conditions of the installation, where through a case study carried out in a hospital, employees who maintain a service provider company, were interviewed. With the results obtained, it was noticed that the maintenance conditions of this installation contribute for the appearance of equipment failures, an action plan was proposed, with in order to contribute to increase the reliability and availability of the system in operation, in order to meet the indoor air quality parameters that were established in the project.
