Computer-Aided Modeling and Analysis of an Energy-Saving Refrigerating System

Energy efficiency is one of the most important objectives in today’s engineering systems. This paper introduces a new type of energy-saving refrigerating system based on functional and performance studies, computer-aided 3-D modeling, computational fluid dynamic analysis, and the prototype testing. The main advantages of this energy-saving regenerative system include: higher performance efficiency due to less frictional force, simplified mechanical system, less vibration due to its symmetrical structure design, less frictional losses between free piston and cylinder, and cost-saving in mechanism due to low tolerance requirement manufacturing of the system components.
