摘要

Irreversible processes in regenerators and heat exchangers limit the performance of cryocoolers. In our research we study the possibility to avoid regenerators in pulse-tube refrigerators (PTR's) by using two identical PTR's operating in opposite phase. The two regenerators are replaced by one counterflow heat exchanger. In this contribution we treat the performances of regenerators and heat exchangers from a fundamental point of view. The losses in the two systems are calculated from the entropy production due to the various irreversible processes. The expressions are brought in special forms which make comparison relatively easy.
