Based on certain assumptions, three different definitions of efficiency were proposed, that is adiabaticefficiency, diabatic efficiency and heat efficiency.
基于一定假设，定义三种不同的效率表达式，即为绝热效率、非绝热效率和传热效率。

The experimental results show that adiabaticefficiency has a remarkable improvement in low cold mass flow ratios, adiabaticefficiency can improve by 30% in the best condition.
实验表明，在冷流率小的情况下，通过加湿可以使得绝热效率得到显著的提高，最好可以提高30%。

The product is applied to transportation and storage of liquid nitrogen, liquid oxygen and other mediums. The adiabaticefficiency is excellent and the usable duration is long.
