Establishing a quality and processes system for portable air conditioner SMAC

Abstract

A mobile air conditioner, SMAC is being manufactured at Akella systems operating at Sreyas institute of engineering and technology. The trial production was successfully done with 25 numbers in the year 2018-19 successfully. The processes of building a SMAC contained several manufacturing jobs like brazing, fabrication tube bending drilling etc., The quality and processes system should be established and configured with some quality assurance to make the product a perfect and comfortable to use with proper guidance. Several processes carried out are established in a sequential order and the processes time is evaluated. Every process is carried out with inspection and quality check. In the first stage receiving inspection of the BOM items is made for each and incoming material like evaporator, condenser, capillary, compressor etc., In the second stage the inspection is done for the elements like bended tubes copper pipes using the receiver gauges. Here the alignment issues are also resolved if present. The assembling of the portable air conditioner is done with the help of machining process like brazing and defects are checked using soap solution test in o0rder to avoid leakages. In the third stage the tests like online tests psychrometric tests are conducted, the refrigeration cycle performance and customer evaluation are checked. This whole process is done for 5 portable air conditioners. After completing the whole processes, the detailed catalogue is setup and this consists of how to operate the remote and steps of installation.
