| 自主调节供水温度及开关部分供暖回路阀门等行为模式对户式空气源热泵地暖系统的节能与舒适性具有重要影响。本文以一实际住宅为例，实验研究了户式空气源热泵地暖系统在不同供水温度和改变供暖回路数量下的供暖特性，对室内空气温度、地面温度及系统耗电量等参数的实测与分析显示：室外平均温度为-2.3 ℃，按照机组最高供水温度55 ℃运行时，由于地面温度过高，地板表面温度局部不满意率超过20%，相对于供水温度30 ℃运行结果，耗电量增加191%，客厅与书房的温差增加2.5 ℃以上。室外平均温度为-1.7 ℃，关闭次卧和客卧相应的地暖回路阀门后，主卧、客厅和书房室温比全屋供暖时分别降低了1.4、2.9、0.5 ℃，系统耗电量降低18.7%。 |

| Abstract: |
| Behavior modes, such as self-regulating water supply temperature and switching valves in heating circuits, have significant effects on the energy-saving and comfort of household air-source heat pump floor heating systems. In this study, using an actual residence as an example, the heating characteristics of a household air-source heat pump floor heating system under different water supply temperatures and different numbers of heating circuits were experimentally studied. The indoor air temperature, ground temperature, and system power consumption were measured and recorded. When the average outdoor temperature and the maximum water supply temperature of the unit was -2.3 ℃ and 55 ℃, respectively, the ground temperature was very high and the local dissatisfaction rate of the floor surface temperature was more than 20%. Compared to the water supply temperature of 30 ℃, the power consumption increased by 191% and the temperature difference between the living room and the study area increased by more than 2.5 ℃. When the average outdoor temperature was -1.7 ℃, after closing the corresponding floor heating loop valves in the second bedroom and the guest bedroom, the room temperature of the master bedroom, living room, and the study decreased by 1.4 ℃, 2.9 ℃, and 0.5 ℃, respectively. Also, the power consumption of the system was reduced by 18.7%. |
