Population growth increasing life level and limitations of energy sources made efficient use of energy sources an inevitable task. The floor heating system has been developed as one of the most energy-efficient systems for heating inside spaces. The adoption of an energy-efficient heating system still requires the provision of acceptable indoor air quality to ensure a healthy environment. In this study, airborne particle distribution inside a space equipped separately with the radiator and floor heating systems is investigated experimentally. The experiments executed in an unoccupied residential room of $3m\times 4m\times 3m$ and sensitivity analyses were performed to unveil the effect of air temperature and floor cover on particle distribution pattern. The room space was divided into eight zones, where the particle concentration of PM2.5 and PM10 are measured by sampling the air. The results reveal that in radiator and floor heating systems, the highest airborne particle concentration is for PM10 and PM2.5 particles, respectively, which are 61% and 39% beyond their maximum allowable limit values. Between PM2.5 and PM10 particles, the concentration pattern of PM2.5 particles is more sensitive to change of both air temperature and floor condition. Also, between the radiator and floor heating system, the sensitivity is the highest in case of using floor heating system. By comparing the total deviation of PM2.5 and PM10 particle concentration from their corresponding allowable limit, the floor heating system is proposed as a more healthy heating system.

人口增长，生活水平的提高和能源的限制使能源的有效利用成为必然的任务。地板采暖系统已被开发为用于加热内部空间的最节能系统之一。采用节能供暖系统仍然需要提供可接受的室内空气质量，以确保健康的环境。在这项研究中，对装有散热器和地板采暖系统的空间内空气中的颗粒分布进行了实验研究。实验是在一个无人居住的房间里进行的$3米\times 4米\times 3米$进行了敏感性分析，揭示了空气温度和地面覆盖物对颗粒分布模式的影响。房间空间分为八个区域，其中通过采样空气来测量PM2.5和PM10的颗粒浓度。结果表明，在散热器和地板采暖系统中，最高的空气传播颗粒浓度分别是PM10和PM2.5颗粒，分别比其最大允许限值高61％和39％。在PM2.5和PM10之间PM2.5颗粒的浓度模式对空气温度和地面条件的变化更敏感。另外，在散热器和地板采暖系统之间，使用地板采暖系统时灵敏度最高。通过比较PM2.5和PM10颗粒浓度与其相应允许极限的总偏差，提出了地板采暖系统作为更健康的采暖系统。
