一种独立式内燃机驱动的船用空调装置试验研究

Experimental Study on Marine Air Conditioning Unit Driven by Combustion Engine

为了研究特种空调装置在中小船舶上的应用特性,研制了一种独立式内燃机驱动的空调装置。该装置采用小型内燃机驱动制冷系统;小型发电机为室内风机和水冷式冷凝器水泵提供交流电力,为柴油机电启动的蓄电池进行直流充电,并且为控制系统提供稳定的直流电力。根据各个部件的额定运行工况,对系统进行了可靠性综合测试。通过调节内燃机转速对系统进行了变工况试验,根据试验数据进行了结果分析,可以看出在保证系统可靠性的前提下调节内燃机转速和蒸发器风机转速可以实现船舱室内温度的精确调节,为我国内陆河流的中小船舶使用特种空调装置提供了一种新的选择。

An independent air conditioning unit driven by a combustion engine was developed to investigate the cabin temperature adjusting characteristic with special air conditioners applied in small or medium-sized shipping. A small combustion engine drives its refrigeration system and a minitype generator provides AC for the indoor fan and the pump of the water-cooled condenser and supplies DC for the storage battery and the control unit. Moreover, general experiments were conducted to validate the reliability of the system based on the rated condition of all components. The variable operating mode test was performed with adjusting combustion engine rotational speed. The experiment results show that adjusting combustion engine rotational speed and evaporator fan rotational speed can regulate the cabin temperature accurately.
