Performance of a 4°K Refrigerator
In an earlier paper, a new refrigeration cycle was described by Gifford and McMahon [1,2]. Since this first paper, several other papers have described performance, improvements, and embodiments of this thermodynamic cycle [3–5]. Several papers point out that the Gifford-McMahon cycle is particularly inefficient when compared to the other cycles [6,7]. This has not, hitherto, been commented on critically.
