Investigation of the spread of pollutants and especially pathogenic particles in the interior of today's buildings has become an integral part of the design of such buildings. When the Coronavirus is prevalent in the world, it is necessary to pay attention to the spread of the virus in the interior of residential apartments. In the present study, the Coronavirus particles emitted from the sneezing of a sick person in the bedroom of a residential apartment were tracked. Meanwhile, the degree of exposure of a mannequin that has been placed in the living room playing the role of a healthy person is examined. In this research, a segregated solution of steady-state flow and an unsteady particle solution have been separately used: a suitable, accurate, and optimal solution in particle studies. A comparison of the results shows that underfloor heating creates a healthier space around the healthy person's respiratory system, but instead, we will see more polluted areas around the sick person. According to the PRE results, the PRE value for a mechanical heating system is higher than a floor heating system. Therefore, it is recommended to use mechanical heating system in the apartments where the person with COVID-19 is hospitalized.
研究污染物尤其是致病颗粒在当今建筑物内部的传播情况，已成为此类建筑设计中不可或缺的一部分。当新冠病毒在全球流行时，有必要关注病毒在住宅公寓内部的传播。在本研究中，追踪了一名患病者在住宅公寓卧室打喷嚏时喷出的新冠病毒颗粒。同时，检测了放置在客厅中扮演健康人角色的人体模型的暴露程度。在本研究中，分别使用了稳态流的分离解和非稳态颗粒解：这是颗粒研究中一种合适、准确且最优的解。结果比较表明，地板供暖在健康人的呼吸系统周围营造了更健康的空间，但相反，在患病者周围会出现更多污染区域。根据PRE结果，机械供暖系统的PRE值高于地板供暖系统。因此，建议在收治新冠肺炎患者的公寓中使用机械供暖系统。
