Abstract:
Background and Aim: Considering that suspended particles are one of the main pollutants of air in cities. Since the prevention of contamination beyond the standard level and the economic and health issues of employees and individuals involved in the enclosed environment is very important, the research team concluded that the effect of fan coils at the dispersion of suspended particles and its effect on air pollution in educational spaces.
Materials and Methods: In this study using the device Haz Dust and NIOSH500 suspended particles were measured in two seasons in the spring and summer and at 128 points.The sampling device was fixed at the center of the room at a height of one and a half meters, and with an impactor of 10 and 2.5 and the teflon filter the amount of contaminants was read on the device before the fan coil is turned on and after reading it turned on and data was analyzed by SPSS 19 software and the value of p-value was calculated and compared with the standard limit.
Findings: The level of pollution in educational spaces is lower than standard, and fan coils have an effect on the dispersion of PM10 particles, but in general, fan coils do not have a significant effect on the dispersion of particles in educational spaces.
Conclusion: The results of this study showed that the concentration of particles in the maximum time is less than standard, and the fan coil has no effect on the amount of contamination of educational spaces.
