Inertane tube pulse tube refrigerator with double action compressor
朱 紹偉 （同済大）
Abstract:If the cooling power of a inertance tube refrigerator is big, such over 1kW, or the refrigeration temperature is high, such as near room temperature, the expansion work is rather large which is worth to recover. There are several kind of methods to recover the expansion work, such as step piston, displacer, double piston. Here, a double acting compressor type in which a back compression space which is 180 degree phase angle with the compression space is connected to the warm end of the pulse tube for recovering expansion work is discussed by numerical simulation.
