In this paper, these factors are chiefly analyzed. Some conclusions are given asfollows: A real cycle system can be controlled according to some regulations to reduce thedifference between the real cycle and its corresponding ideal cycle, There is an optimum cycletime which makes the refrigeration power density the greatest.展开更多
