| 中文摘要: |
| 目的 研究低温条件下空气源热泵的烘干性能。方法 论文主要采用焓差法研究在换热面积和室外温度(温度为7、−12、−20 ℃，相对湿度为65%)不同时，空气源热泵的制热量、输入功率、能效等性能。结果 在7 ℃环境中，增加室内侧换热器面积，热泵的制热量提高了19%，系统能效提升了14%，但输入功率增加了5%;在−12~−20 ℃环境中，增加室内侧换热器面积，热泵的制热量提升了5%，系统能效提升明显，最大可提升27%，输入功率最大降低为17%。结论 增加室内侧换热器面积，系统焓差降低，但是能提高系统在低温下的循环风量，制热性能更加优异。 |

| The work aims to study the drying performance of air source heat pump at low temperature. The enthalpy difference method was used to study the heating capacity, input power and energy efficiency of air source heat pump under different heat transfer area and outdoor temperature (temperature:7, −12, and −20 ℃ and relative humidity:65%). In 7 ℃ environment, increasing the area of indoor heat exchanger could increase the heating capacity by 19%, the coefficient of performance of system (SCOP) by 14%, but the input power by 5%. In the environment of −12-−20 ℃, as the area of indoor heat exchanger increased, the heat output of the blower could be increased by up to 5%, the SCOP of the system could be increased by up to 27%, and the input power could be decreased by up to 17%. The enthalpy difference can be reduced by increasing the area of the indoor heat exchanger, so the circulating air flow rate can be increased at low temperature, providing better heating performance. |
