| With the continuous development of society,people living conditions have a leapfrog requirements,the vast majority of families are still in improving and improving the comfort of living conditions stage.The core concep t of future residential design is people-oriented,improve people’s living comfort.This article mainly to the radiator in different indoor installation position on the comfort and energy saving analysis,for future indoor heating system design radiator installation reference.The position,appearance and comfort questionnaire surveys on the radiator heating radiator installation: the family accounted for 68%,still occupy a dominant position;although most families will be installed in the radiator under t he window,but there are still 44% other families will be installed in the position of radiator non sill,accounted for a small proportion;installation of 72% families in the selection of radiator is from the aesthetic perspective,rather than from a better heating effect to consider.Simulation experiment is for a room in a district of Beijing city as a model of heat transfer mathematical model,simulation software is simulated by FLUENT numerical calculation and analysis of the radiator in the room and t he vertical distribution of horizontal distribution of different positions of the indoor temperature condition.From the simulation results,we can see that when the radiator is arranged on the side wall of the window,the heating effect is not worse than that arranged under the window sil.Experimental study on the model selection is a district of Beijing C ity,a room,selected the two radiator experiment by measuring the level of temperature inside the room and come to the conclusion that the vertical temperature radiator arranged in the window side wall than the layout in the windows when the indoor average temperature of 0.35 DEG C above the radiator;in the window side wall,perpendicular to the direction of each height temperature was higher than that of the radiator arranged in the window;the window is arranged in the radiator side wall,close to the outer window at each measuring point temperature was higher than the layout under the window,but away from the window at the temperature of each point is arranged on the windowsill is low.The radiator is better positioned in the window than under the windowsill to get better comfort.By calculating the PMV-PPD comfort index,the radiator arranged in the window of the side wall is lower than the layout in the window more people feel too hot,can reduce the indoor temperature by reducing the radiator heat dissipation capacity,achieve the purpose of energy saving. |
