摘　　要：应用CFD软件模拟直河道水源热泵空调系统冷却水热量对河水温度场的影响,就河水温度场随空调系统冷却水流量和温度的变化以及河水的蓄热能力展开研究,得出系统冷却水与河水之间合理的流速比和流量比,以及河水最高温度和平均温度沿河水流动方向的变化情况。The effects of the temperature field of the straight river water source heat pump air-conditioner system are simulated in this paper, basing on the numerical simulation software of CFD. Problems of the temperature field of river water changes along with the cooling water flow and temperature of the air-conditioner system are discussed. This paper comes to the reasonable velocity ratio and flow ratio of the cooling water and the river water, and the change of the river water＇ s maximum temperature and average temperature along the flow direction.
