基于热泵预处理的复合除湿系统实验分析OA

To address the decline in dehumidification performance of rotary dehumidifiers under high-temperature and high-humidity conditions,this paper proposes a hybrid dehumidification system based on heat pump pre-treatment.The system fully utilizes the evaporative cooling and condensing heat of the heat pump to pre-cool and pre-heat the air processed by the rotary dehumidifier and the regeneration air,effectively enhancing the dehumidification capacity of the system while reducing regeneration energy consumption.Through experimental research on the hybrid dehumidification system,the dehumidification capacity of the system was studied and analyzed.The results show that when the ambient temperature is 34.0 ℃ and the relative humidity is 59％,the temperature and absolute humidity of the processed air decreased by 20.1％and 8％,respectively.Compared to the traditional rotary dehumidification system,the regeneration energy consumption was reduced by 28.6％.Additionally,under different operating conditions,the range of improvement in dehumidification capacity of the hybrid dehumidification system compared to the traditional system was between 73.9％and 8.02％,with energy-saving rates ranging from 28.8％to 19.3％.The research results provide experimental data support for the application of the hybrid dehumidification system.
