机械振动对吸收式制冷强化作用的理论与试验研究

Theoretical and Experimental Study on the Enhancement Effect of Mechanical Vibration on Absorption Refrigeration

针对吸收式制冷机的传热传质过程,提出了一种通过振动来强化其过程的方法。搭建了相关的试验台,将一台吸收式制冷机组放置在一个电动振动台上,电动振动台的频率和振幅可调节,对吸收式制冷机组在振动情况下的运行情况进行了试验研究,探究振动对其传热传质的强化效果。

A new method of enhancing the heat and mass transfer process of absorption refrigerating machine by adding vibration into the system.Relevant test bench had been set up thus an absorption refrigerating unit was put on the top of the vibration table and the frequency and amplitude of the vibration table can be regulated to change the running conditions of the absorption refriger-ating unit to explore the effects of vibration on the heat and mass transfer process of absorption refrigerating machine.
