设计一种由太阳能供电、空气源热泵换热器与亭壁一体化的供暖岗亭.首先,建立一体化岗亭设备模型,并采用Matlab语言编制仿真程序,对岗亭进行性能模拟;然后,选取太原某日工况,对岗亭模型进行实验验证,并对其供暖季性能进行分析.结果表明:亭壁蒸发器吸收室内外两侧空气热量、得热量比相同条件下,常规风冷蒸发器高31.41%;供暖季系统性能系数(COP)为3.22~4.96,平均COP值为4.18,高于常规风冷热泵,节能效果良好;供暖季太阳能发电量可满足岗亭热泵压缩机耗电量需求,证明岗亭可实现供暖零能耗.

Research on Heating Performance of Booth With Air-Source Heat Pump Heat Exchanger and Pavilion Wall Integrated

A heating booth integrated with solar energy, air source heat pump heat exchanger and booth wall was designed. Firstly, an integrated booth equipment model was established, and the Matlab language was used to make simulation programs, to simulate the performance of the booth; then, the conditions on a certain day in Taiyuan were selected, and the booth model was verified experimentally and its heating performance analyzed. The results show that the kiosk evaporator absorbs the heat of the air on both sides of the room and the outside, and the heat gain is 31.41% higher than that of the conventional air-cooled heat pump when the heat gain ratio is the same; the coefficient of performance(COP)is between 3.22 to 4.96 in the heating season, with the average COP value 4.18, which is higher than that of the conventional air-cooled heat pump, energy-saving effect is good; solar power generation in the heating season can meet the power needs of the booth heat pump compressor, which proves that the booth can achieve zero energy consumption of heating.
