摘　　要：空气源热泵作为一种清洁取暖方式已在我国广泛采用,但空气源热泵末端往往安装在卧室上部,冬季使用其采暖时,热空气难以下降,热舒适性差。基于人体的行为习惯及对卧室空调的使用习惯,实验研究了不同送风参数组合送风工况下床表面空气温度和速度的动态变化以及卧室垂直方向空气温度分布,并进行了热舒适性评价。结果表明:当长时间躺在床上时,不建议45°低温送风,建议0°或90°送风;当在床边久坐时,建议90°中低温送风;当在床上久坐时,不建议45°持续高温送风,建议90°送风。这能指导人们获得更好的热舒适性,并为空气源热泵末端的优化以及制定其供暖模式的智能控制策略提供支持。As a clean heating method,air source heat pump is widely used in China.However,the end of the air source heat pump is often installed on the upper of the bedroom.When it is used for heating in winter,it is difficult for hot air to fall to the lower of the room,and the thermal comfort is poor.Based on the human behavior habits and the usage habits of bedroom air conditioner,this paper aims at the experiment on the dynamic changes of bed surface air temperature and velocity under different air supply parameters combination,obtaining the vertical air temperature distribution in the bedroom and evaluating the thermal comfort of bed surface.The results revealed that when lying in bed for a long time,it was not recommended to supply air at 45°low temperature,but to supply air at 0°or 90°.When sitting at the bedside for a long time,it was recommended to supply air at 90°medium and low temperature.When sitting on the bed for a long time,it was not recommended to supply air at 45°continuous high temperature,and it was recommended to supply air at 90°.The results can provide guidance for people to obtain better thermal comfort,and provide support for the optimization of the end of the air source heat pump and the formulation of intelligent control strategies for its heating mode.
