提出了将太阳能烟囱效应与太阳能光伏光热(PV/T)技术相结合来强化地下空间通风的技术措施。为研究该通风模式的影响因素,基于质量和热量平衡理论,建立了风井通风性能的数学模型,分析了换热器管排数、风井高度、热水水温和流速对通风性能的影响。结果表明:风井内换热器存在最大有效管排,管间距为0.032、0.038、0.047 m时换热器的最大有效管排数分别为9、13、18,在有效管排数范围内,随着管排数的增加风井出口温度升高,通风量先增大后减小;空气质量流量随着风井高度增加、热水温度升高明显增大,随着热水流速增大而缓慢增大;风井出口空气温度随着风井高度增加而降低,随着热水温度升高、流速增大而升高。最后,通过拟合得到计算风井空气质量流量的经验公式。 The technical measures to strengthen the ventilation in underground space by combining the solar chimney effect with the solar PVP technology are proposed. In order to study the influencing factors of the ventilation mode, a mathematical model of ventilation performance was established based on the theory of mass and heat balance, and the influence of ventilation tube row number, shaft height, hot water temperature and flow rate on ventilation performance was analyzed. The results show that the maximum effective tube row exists in the heat exchanger inside the air shaft, the maximum effective tube rows of the heat exchanger are 9, 13 and 18 when the tube spacing is 0.032, 0.038 and 0.047 m, respectively. Within the range of effective tube rows, With the increase of tube row number, the exit temperature of the air shaft increased and the air volume first increased and then decreased. The air mass flow rate increased with the height of the air shaft, and the temperature of the hot water increased obviously. As the hot water flow rate increased, Increases; the air outlet air temperature decreases with the increase of air shaft height, with the hot water temperature increases, the flow rate increases and increases. Finally, the empirical formula for calculating the air mass flow of the air shaft is obtained through fitting.
