演讲内容摘要：
Alternative cooling technology by use of Stirling cycle has been considered for application in domestic and commercial refrigerators by virtue of environmental friendliness. A V-type integral Stirling-cycle refrigerator (VISR) developed by authors consists of an expansion cylinder,a compression cylinder and a heat exchanger in-between. The expansion piston and compression piston are V-shaped and driven by a crank-connecting rod mechanism. A cold head is connected to the expansion piston and provides cooling capacity. The rotor of an electrical motor is directly installed at the crank shaft and they have a semi-hermetic configuration. The parameter optimization is important for the VISR design,but the optimal parameters are great different with various configurations and their working conditions. The
design parameters such as a consumed power and Coefficient Of Performance (COP) that maximize its thermal performance are investigated under the various working conditions changing a rotating speed,working substances and charged pressures. The results are given by diagrams which benefit the
theoretical basis for optimal design and operation of the V- type integral Stirling refrigerator. Characteristic curves for the cooling unit are presented so that the system performance would be estimated for the different applications.
