摘要: 空调制冷后机内残余的水分使得空调内部形成高湿的环境,是空调产生异味、细菌、霉菌的主要原因。热泵干燥技术使空调内部防菌防霉,是保证空调能够健康使用的必要手段。基于新风空调创新性设计出的内机排气系统,能够将空调内部的水汽排出到室外,不影响用户使用时的舒适性体验。先从理论上分析得出干燥后的机内含湿量需小于等于制冷后干燥前的含湿量的结论,接着设计正交实验得知影响机内残余水量的主要因素,最后,根据干燥实验结果推断出空调内机干燥率的计算公式,得到空调干燥后足够长时间内保持低湿度(≤70%),并有持续降低的趋势及机内干燥率≥99%的结论,并作为判断空调内机干燥的依据,为后续热泵空调干燥技术研究提供技术借鉴。

Abstract: The residual moisture inside the air conditioner after cooling creates a high humidity environment, which is the main cause of odor, bacteria, and mold production in the air conditioner. Heat pump drying technology is a necessary means of preventing bacteria and mold inside air conditioners to ensure their healthy use. Based on the innovative design of fresh air conditioning, an internal exhaust system has been developed, which can discharge the water vapor inside the air conditioner to the outside without affecting the user's comfort experience during use. Firstly, it is theoretically analyzed that the moisture content in the air conditioner after drying should be less than or equal to the moisture content before cooling and drying. Then, an orthogonal experiment is designed to determine the main factors affecting the residual water content in the air conditioner. Finally, based on the results of the drying experiment, the calculation formula for the drying rate of the air conditioner unit is inferred. The conclusion is that the air conditioner unit should maintain low humidity (≤ 70%) for a sufficient period of time after drying, with a continuous decreasing trend and a drying rate of ≥ 99%. This serves as the basis for judging the drying of the air conditioner unit and provides technical reference for subsequent research on heat pump air conditioning drying technology.
