This paper reports a theoretical analysis and experimental investigation of pulse tube refrigerator. A concept of steps is introduced for the derivation of cold end temperature with zero heat pumping rate (Tco). This relation indicates that Tco depends not only on the length ratio, hot end temperature, and ratio of specific heats of gas used, but also on the pressure ratio employed. An empirical relation for heat pumping rate is also suggested. Experimental investigation indicates that there exists an optimum hot end length and that the optimum speed decreases with increase in the total length of pulse tube.
