Numerical simulation and experimental of summer cooling of passive solar houses in northern villages
Four different cooling measures were proposed to aim at the excessive indoor temperature problem of passive solar house in summer. A passive solar house in the Shihezi area of Xinjiang was taken as the study object. The method of numerical simulation combined with an experimental test was used to compare and analyze the cooling effect of the four cooling measures. The results show that: comparing the numerical simulation results with the experimental results, the average value of the indoor temperature deviation under each cooling measure is 2 ℃, but the temperature change trend is consistent and has good conformity, which confirms the feasibility of the numerical simulation. Compared with the passive solar house in the natural state, thermal comfort requirements can be met 46%, 50% and 50% of the time, respectively. Using shading, closing the south window combined with shading or thermal pressure ventilation, thermal pressure ventilation combined with shading achieves thermal comfort requirements 92% of the time.
