发布时间：2018-10-14 17:15
【摘要】：现有风冷吸收分别对传热与传质加以强化,绝热吸收有助于实现吸收器小型化,但存在溶液再循环量过大和再循环泵能耗大的问题。该文结合喷射器与超声波二者优势,以实现太阳能吸收式制冷机小型风冷化、高效化为目标,提出一种基于喷射器-超声波的绝热吸收制冷循环,以期利用喷射器回收溶液节流损失并提高吸收器压力,减少再循环倍率,利用超声波在绝热吸收器内的真空雾化增大吸收传质过程空间和时间,增强吸收效果。
[Abstract]:The existing air-cooled absorption enhances heat and mass transfer respectively. Adiabatic absorption is helpful to realize the miniaturization of absorber, but there are some problems such as excessive recirculation of solution and high energy consumption of recirculating pump. Based on the advantages of ejector and ultrasonic, a new adiabatic absorption refrigeration cycle based on ejector and ultrasonic is proposed in this paper, aiming at the realization of small air cooling and high efficiency of solar absorption refrigerator. In order to recover the loss of solution throttle and increase the pressure of absorber and reduce the rate of recirculation, the vacuum atomization of ultrasonic wave in adiabatic absorber is used to increase the space and time of absorption mass transfer and enhance the absorption effect.
