余热驱动冷管组合式吸附空调的制冷特性

以小型运输车船驾驶室空调为应用背景,设计并建造了余热驱动的冷管型组合式吸附空调系统.针对单台组合式吸附空调器进行了一系列的性能试验.研究分析了组合式吸附空调器在不同热源温度、环境温度、冷媒配风量和循环周期下的制冷特性.结果显示,在一定的范围内热源温度、冷媒配风量的提高,有利于整个空调系统性能的提高;环境温度的升高使空调系统的性能有所下降;而循环周期有一个最优范围.试验证明,对于该冷管型组合式吸附空调系统,其循环半周期选定在30 min左右是较合理的.

Refrigerating properties of cooling-tube-knockdown adsorption air conditioner powered by waste heat

A cooling-tube-knockdown adsorption airconditioning system powered by waste heat has been designed and manufactured,which is used to attempt to provide air conditioning in the driver's cab of transportation vehicles or boats.A series of performance experiments for the adsorption air conditioner were carried out.The refrigerating properties of the adsorption air conditioner were studied and analyzed under different heat source temperatures,ambient air temperatures,cold medium air quantities,and cycle times.The results show that within a certain scope the rise of heat source temperature and cold medium air quantity,and the decrease of ambient air temperature are helpful for the improvement of performance of airconditioning system.There exists an optimum range for the cycle time and the experiment study indicates that the cycle time of 30 minutes selected is more reasonable for the adsorption air conditioner.
