| Abstract (English): |
In contrast with the conventional drying technology, a novel air cycle heat pump drying (ACHPD) system, which uses air as its working medium, is proposed to solve the problems of low energy efficiency and eliminate the use of HCFCs/ HFCs. A simulation model is established, and its verification via experimental results from a constructed test bench indicates errors of the drying rate within ±0. 01% and the system power within ±7%. Compared with a conventional electric heater drying (EHD) system, the energy-saving rate of the ACHPD system reaches 15%-27% when the water evaporation rate increases from 0. 75 kg / h to 3. 45 kg / h. The increase of the inlet air temperature is 10-40 ℃ and the relative humidity is 30%-80%, which reduces the moisture extraction ratio(MER) by approximately 7% and 21%, respectively. The efficiency improvements of the expander and compressor are 0. 55-0. 8 and 0. 4-0. 9, respectively, which can deteriorate the energy efficiency of the system by 17% and 36%, respectively. The research results provide new technical references for the application of heat pump technology in the drying field. [ABSTRACT FROM AUTHOR] |

为解决能源使用效率低、HCFC/ HFC 等非环保制冷剂使用等问题,提出了不同于传统干燥技术的以空气为工质的空气 循环热泵干燥(ACHPD)系统新技术。 建立了数学仿真模型,通过所构建实验台的实验结果进行验证,干燥速率误差在±0. 01% 以内,系统功率误差在±7%以内。 与传统的电加热器干燥(EHD)系统相比,当水质量蒸发率从 0. 75 kg / h 增至 3. 45 kg / h 时, ACHPD 系统的节能率达到 15% ~ 27%。 进气温度由 10 ℃增至 40 ℃和相对湿度由 30%增至 80%分别使单位除湿能效比(MER) 降低约 7%和 21%。 膨胀机效率由 0. 55 增至 0. 8 和压缩机效率由 0. 4 增至 0. 9 会使系统的能效分别降低 17%和 36%。 [ABSTRACT FROM AUTHOR] |
