The critical temperature ratio of self-excited oscillation heat driven cooler that consists of prime mover unit with wet regenerator, cooler unit with dry regenerator and liquid piston was calculated. The critical temperature ratio of prime mover was calculated for the target temperature of the cooler unit. Furthermore, the calculation results were compared under the condition that the regenerators were dry or wet at prime mover unit. Under the condition which the target temperature ratio of cooler unit was set to 0.92, the critical temperature ratio of dry regenerator was 1.55. On the other hand, the critical temperature ratio of wet regenerator was 1.14.
