The relation between the optimal efficiency and power output of the engines for an ideal or van der Waals gas as a working fluid is derived. 導出這類(lèi)熱機以理想氣體或范德瓦耳斯氣體為工質(zhì)時(shí)的最佳效率與輸出功率間的關(guān)系。
To take advantage of the temperature glide matching of working substances and heat resources is an very importment reason of using non-azeotropic refrigerants. 選用非共沸工質(zhì)的一個(gè)重要原因是為了利用其溫度滑移特性以匹配熱源流體的溫度變化，減少換熱過(guò)程的不可逆性。
