Reliability Measurement Technique for Evaporator used in Domestic Refrigerators
Journal Title: International Journal of Current Research and Review - Year 2017, Vol 9, Issue 8
Abstract
Introduction: The evaporator used in domestic refrigerator is a heat exchanger in which the heat exchanging occurs by the mean of air. In general the reliability of evaporator is considerably high. It is seen the technical problems arising in evaporator is comparatively lesser than the other components used in it such as compressor, condenser and filter drier etc. But during long run of its use the problems arise in different components of evaporator such as due to leakage of refrigerant, choking or blockage of evaporative coil etc. Aim and Objectives: The aim is to find the reliability of evaporator used in domestic refrigerators, working on the principle of vapour compression refrigeration system. Material and Methods: The data used for analysis is collected from a reliable workshop and a system dynamic method is used for the analysis on Vensim-PLE modeling software. Result: In result output table for year wise reliability of important components are shown. The comparative graph of reliability is also given to easily compare the reliability of each sub components. Conclusion: In this research paper a newer technique is used to calculate the time based reliability of evaporator used in domestic refrigerator. This method of calculation is also applicable for all types of dynamic system. The reliability of evaporator appears almost 95.45% at the end of fifteenth year.
