摘要: 移动空调打水系统能有效利用冷凝水冷量并提升冷凝水排除能力。为优化冷凝水的利用,研究了打水系统对冷凝水的生成和利用情况,以及对整机性能的影响,进而研究了冷凝器流程对冷凝水利用的影响。结果表明:85%~97%相对湿度工况下,打水系统能够使74.69%~93.57%的冷凝水蒸发,且绝热加湿理论分析表明该工况下的移动空调具有将剩余冷凝水全部蒸发的潜力;流程对比研究表明确保冷凝器高温侧充分与冷凝水接触,可进一步提升整机的冷凝水排除能力,流程优化后名义制冷量提升1.31%,能效(EER)提升2.42%,95%相对湿度下连续运行时长由0.4小时延长至5.5小时;同时流程对比实验表明,冷凝器设计需综合考虑空气对流换热和冷凝水蒸发换热,在制冷量和能效满足要求时,增强冷凝水蒸发换热可以提升冷凝水排除能力。

Abstract: The water pumping system of portable air conditioner can effectively utilize the cooling capacity of the condensate and improve the removal of condensate. In order to optimize the utilization of condensed water, studies the influence of the water pumping system on the generation and utilization of condensed water, as well as the impact on the performance of the whole machine, and then study the impact of condenser flow paths on the utilization of condensed water. The results show that: under the condition of 85%~97% relative humidity, the water pumping system can evaporate 74.69%~93.57% of condensed water, and the theoretical analysis of adiabatic humidification shows that portable air conditioner under this working condition has the potential to evaporate all the condensed water. The comparative study of the condenser flow paths shows that ensuring that the high-temperature side of the condenser is fully in contact with the condensate, which can further improve the condensate removal capacity. After optimization, the rated cooling capacity is increased by 1.31%, the energy efficiency (EER) is increased by 2.42%, and the continuous operation time without overflow under the condition of 95% relative humidity is extended from 0.4 hours to 5.5 hours. In addition, the comparative study of the condenser flow paths shows that the design of the portable air conditioner condenser needs to comprehensively consider air convection heat transfer and condensate evaporative heat transfer. On the premise that the performance meets the requirements, increasing the proportion of condensed water evaporative heat transfer can improve the condensed water removal capacity.
