摘要
房间空调器作为重要的室内空气调节设备,不仅要保证快速制冷和制热的需求,还要满足热舒适性指标,如温度均匀度、垂直空气温差和吹风感指数等。针对一款安装于卧室的带无风感功能的常规冷暖型壁挂式空调,测试了其在高温工况制冷和低温工况制热运行时室内空间对应的温降和温升情况,得到了室内空间的温度分布,并对比了相同制热条件下导风条摆风和不摆风对室内温度场的影响。完成了制冷无风感模式下室内温降试验和吹风感指数与平均风速试验,研究了空调在无风感模式下的室内热舒适性情况。结果表明,制冷时沿高度方向无明显温度分层。制热模式开启上下摆风,可有效改善房间温度分层。制冷无风感模式在保证降温效果的同时可降低吹风感。
As an important indoor air conditioning equipment,residential air-conditioner should not only ensure the demand of rapid cooling and heating,but also meet thermal comfort indicators,such as temperature uniformity,vertical air temperature difference,draught rate and so on.A conventional cold and warm wall-mounted air-conditioner with no wind-sensing function installed in the bedroom was tested for the corresponding temperature drop and temperature rise of the indoor space,during its working of cooling under high temperature conditions and heating under low temperature conditions,the temperature distribution of the indoor space was obtained,and the effects of swing air and no-swing air of the air guide strip on the indoor temperature field under the same heating conditions was compared.The indoor temperature drop test,draught rate and average wind speed test of cooling no-wind-sensing mode were finished,and the indoor thermal comfort of air conditioning under no-wind-sensing mode was studied.The results indicated no-obvious-temperature stratification along the height direction during cooling.The heating mode with air guide strip to swing the air up and down weakened the room temperature stratification effectively.The cooling no-wind-sensing mode assured excellent cooling effect and also contented the requirements of reducing draught rate.
