The longer heat recoverytime slows the speed of adsorber temperature-up and temperature-down so as to effect on refrigerating power and COP.
同时长时间回热也减慢了吸附床的升降温速率，影响了系统运行的制冷量和能效比。

The affects of sort of surfactant, mass ratio of compound surfactants, heating temperature and time on the oil recovery were investigated.
考察了表面活性剂种类、复合表面活性剂的配比、加热温度和时间等条件对油分回收率的影响。

Result shows that decreasing fluid rate and shortening switching time can decrease the temperatureof the exhaust gas and increase the recovery rate of waste heat.
