摘　　要：本文采用通风软件AirPak 3.0建立物卵模型和数学模型,模拟地板送风系统供冷运行和供热运行的室内空调环境研究不同送风温度和不同送风量对地板送风空调房间速度分布、温度分布、热舒适性和空气品质的影响。结果表明:供冷运行时房间设定温度为26℃,送风温度为18~19.5℃,热力分层良好,热舒适性适中,可作为空调系统运行的最佳工况;供热运行时,房间设定温度为18℃,送风温度为28~30℃时,温度分布趋势接近理想采暖要求,能够满足人体的热舒适需求。This paper established the physical model and mathematical model by AirPak 3.0, simulated the air-conditioned indoor environment under cooling and heating operating conditions, analysed the influence of different supply air temperatures and different sup- ply air volume on the velocity distribution, temperature distribution, thermal comfort and air quality of UFAD air-conditioned room. The results showed that： under cooling operating condition, good thermal stratification and thermal comfort can be reached when the room temperature is 26 ~C and the supply air tempera^tre is 18 - 19.5 ℃ , which can be regarded as the best operating condition; under heating operating condition, when the room temperature is 18 ℃ , supply air temperature is 28 - 30 ℃ , the temperature distribution became good enough to meet the needs of the body＇s thermal comfort.
