空调房间热环境实测与模拟

Thermal Environment Measurement and Simulation in Air-conditioned Room

分体式空调能够按需启停,在一些使用场景下具有节能优势,但是对于其室内热环境研究较少。通过对分体空调办公室工位在供冷工况下的实际测量和热环境数值模拟,得到了房间的热环境数据,分析了空调房间的温度、风速和湿度。研究结果表明,室内温度可以达到空调设定值,温度分布下低上高,测试工位垂直温差最大值1.7℃;室内大部分空间的风速值较低,但出风口下方局部风速过高,可达0.89m·s^(-1);室内湿度分布较为均匀一致,工位测点的综合温湿度表现满足舒适度要求。

The split air conditioner can start and stop by demand,which has the advantage of energy saving in some circumstance,but there is little research on its indoor thermal environment.Through the actual measurement and numerical simulation,the data of the thermal environment of the office with split air conditioner was obtained.The distribution of temperature,air speed and humidity in the air-conditioned office were analyzed.The results show that the indoor temperature can reach the set value of air conditioning.The temperature distribution is low at the bottom and high at the top.The maximum vertical temperature difference of the test seat is 1.7℃.The air speed of most indoor spaces is low,but the air speed under the inlet area is up to 0.89 m·s^(-1).The indoor humidity distribution is relatively uniform.Considering the humidity and temperature,the comfort performance of the seat measuring point is relatively satisfactory.
