| Stirling refrigeration cycle cooling rate and entropy production rate of the coordination of optimal performance
Coefficient of zero and a c, the cooling rate R is zero. With (1O), (11) -type analysis is not difficult to know the Stirling cooler in the study of the ecological optimal performance , taking into account the cooling rate can not be zero , then back to the heat loss has the following requirements , namely, c a Rolnv ~. > 1-1 ' W (17 (16 ), ( 17) in fact is to consider the overall coordination of the Stirling cooler optimize performance , the loss of regenerative heat exchanger efficiency and optimization criteria. 4.2 most Good input power according to P a , e , and R a fine fish of a second pad can be obtained , when the objective function E to be the maximum input power of cooler P-c = c a iv , ( 1  is to consider R Optimize performance and coordination , the Stirling cooler is most economical and reasonable energy input power case + one the best . l 4 transfer law one by one loop induced Manchester Linzhi Ling Ling rate and optimizing the coordination of entropy production rate Performance of the regenerator 21, the ideal rate of 4.3 cases in the case of an ideal regenerator , a 1,tory burch, c = 0, from ( 12), ( 13), ( 14) and (18 ), we have 1 + dry = _ - - Ding delicate dried noodles _ 『 dry one by one (n a) one ( Ding Yinan ) a smothering ±! two ! THTL (19) (20) (Z1) ( a ) (22 ) (19 ) a (22) is given Return to heat in the ideal case . consider the thermal irreversibility and time of return to heat , the Stirling cooler best performance of the overall coordination . |
