Maintenance Management of Engineering Assets Assignment - 1
Maintenance Management of Engineering Assets - Assignment Example Ventilation systems allow for the supply of air into the building and cooling in normally necessary to lower the temperatures The boilers: The boilers normally produce water that is hot and in some instances produce steam to be distributed in the space within which the system operates. This is achieved either by the use of coils or the use of water pipes leading to the radiator of the HVAC system. The chiller: This is the cooling component of the system. It is normally treated with air that is normally blown over the coils carrying the chilled water in the space of operation for cooling to take place through the ventilations. The fault tree analysis (FTA) can be used to analyze the major faults that are likely to occur in the HVAC system. The major faults that are likely to be encountered in the system can either be controller based or mechanical faults. The FTA diagram below analyses these faults. Control faults of the HVAC system occur in the functional components of the system. The faults can be in the form of variations in the thermal conductance of the fluid in the coils, dehumidification faults and non-linearity in the variation of the control system. These faults in the control system can only be solved through maintenance operations of the system. This is a procedure that is used for the evaluation of the various aspects of a functional system so that we are in a position to identify the critical failures that are likely to occur in the system so that we can be able to minimize or eliminate them through correction of designs. The main objective of Failure Modes and Effects Analysis (FMEA) is to make a determination of the parts that have the highest probability of failing in an assembled system (Salsbury, 2003). The process of Failure Modes and Effects Analysis (FMEA) starts with the smallest components of the system and
