| 茯砖茶发酵、干燥过程中，烘房内温湿度稳定性和能源系统低能耗是保证茯砖茶品质与成本的重要因素。本文采用TRNSYS仿真与实验研究相结合的方法，对咸阳某茯砖茶厂实际使用的空气源热泵系统进行建模，通过研究各季节典型代表月烘房温湿度的波动情况，确定该空气源热泵系统在全年的运行状态是否满足工艺要求，在此基础上，对比了该系统在全年可运行季节代表月与该生产厂房早期使用的燃气锅炉系统的能耗仿真结果，对空气源热泵系统的节能与环保特性进行研究。结果表明：由于夏季送风质量流量过大且室外空气含湿量较高，7月烘房温湿度不满足工艺要求。热泵系统在1、4、10月的总标煤消耗量的平均值是锅炉系统的44.42%，平均CO2、SO2、NOx排放量分别为锅炉系统的34.13%、44.1%、40.60%。在茯砖茶发酵、干燥的过程中，相比于燃气锅炉系统，空气源热泵系统具有更好的节能与环保特性。 |

| Abstract: |
| During the fermentation and drying of Fu Brick Tea, the stability of temperature and humidity in the oven and the low energy consumption of the energy system are important factors for ensuring the quality and cost of the tea. In this study, the Transient System Simulation Tool (TRNSYS) and experimental research were combined to studythe air-source heat pump system used in a Fu Brick Tea factory in Xianyang. By studying the changes in temperature and humidity in the typical monthly drying room in each season, the operating state of the air-source heat pump system during the whole year was assessed to determine whether it met the technological requirements. On this basis, the simulation results of the energy consumption of the system in the representative month and the gas boiler system used in the early stage of the production plant were compared, and the energy-saving and environmental protection characteristics of the air-source heat pump system were studied. The results showed that in January, April, and October, the average standard coal consumption of the heat pump system was 44.42% of the boiler system, and the average emissions of CO2, SO2, and NOx were 34.13%, 44.1%, and 40.6% of the boiler system, respectively. In the fermentation and drying process of the tea, the air-source heat pump system had better energy saving and environmental protection characteristics than the gas boiler system. |
