Experimental Investigation of the Performance of a Water-Cooled Serial 700 Packaged Reciprocating Chiller
Subject area: Science,Engineering and Technology · Area of research: Mechanical Engineering (Refrigeration)
Abstract
The widespread use of packaged units of all sizes requires interpretation of catalogue data by application engineers, sales engineers and others including end users. The first step is to be certain of the basis of the published data and consider in what ways this will be affected by different conditions. Hence, compressor capacity and power requirements are determined accurately only by actual testing of the compressor in a laboratory. This project, therefore aims at testing the performance of a packaged water-cooled reciprocating chiller manufactured by DUNHAM-BUSH. A performance testing rig was constructed to achieve this purpose and in the instrumentation of the test facility, effort was made to ensure that all sensors are fixed or placed to reflect actual situations. Instruments are interfaced to a microcomputer, both to record data and to process them automatically. From the results of the operation tests, it was found that the capacity of the chiller varied from a maximum value of 27.83KW at start-up to a value of about 20KW at steady state. To achieve a better coefficient of performance, it is recommended to increase the tube side heat transfer in the condenser by keeping the water velocity as high as possible and a water temperature rise of 5Kare good targets to aim for.
