摘要:
文中提出一种地板直喷式多联机热泵系统,以水平管程相差约35 m的山西省太原市内某建筑二层内两个房间为研究对象,对该系统在夏季供冷时的房间内地板表面平均温度、竖直温度分布、室内温湿度进行测量实验.利用Airpak 3.0软件,模拟房间的温度场、速度场,以及PMV(predicted mean vote),PPD(predicted percent dissatisfied)的分布.结果表明:模拟结果与实验结果基本一致,即采用地板直喷式多联机热泵系统夏季供冷,可以有效保证管程较长房间的地板表面平均温度,且与管程较短的房间地板表面平均温度相差在1 ℃左右;各房间同等高度温差也小于2 ℃;地板表面无结露现象;人员工作区域内-1.5≤PMV≤1.2,PPD≤20%,舒适性良好.
Abstract:
A floor direct injection multi-line heat pump system was proposed to cool the building in Taiyuan City. Taking two rooms with the difference of about 35 m in the horizontal pipe length on the second floor as the research objects, the average floor surface temperature, vertical temperature distribution, indoor temperature and humidity during summer were measured. The temperature field, velocity field, predicted mean vote(PMV)and predicted percent dissatisfied(PPD)distribution of the rooms were simulated by Airpak 3.0 software. The simulation results are in good agreement with the experimental results. The results show that using the floor direct injection multi-line heat pump system in summer, the floor surface temperature of the room with long pipe length can be effectively guaranteed, and the average floor surface temperature difference to the room with short pipe length is about 1 ℃. The temperature difference of each room at the same height is less than 2 ℃; no condensation phenomenon on the floor surface; in the working area,-1.5≤PMV≤1.2,PPD≤ 20%, good comfort in two rooms.
