چکیده

در استخرهای سرپوشیده به علت حضور گسترده افراد با شرایط متفاوت، طراحی سیستم تهویه مطبوع که توانایی ایجاد شرایط آسایش حرارتی برای اکثریت افراد حاضر را داشته باشد اهمیت پیدا می‌کند. افراد حاضر در استخر از نظر شرایط بدنی و جنسیت با یکدیگر تفاوت داشته و نیاز است تا تأثیر این عوامل بر آسایش حرارتی افراد بررسی شود. بر این اساس، در این تحقیق با استفاده از مدل آسایش حرارتی انفرادی سه نقطه‌ای به ارزیابی تأثیر عوامل فردی بر احساس حرارتی افراد حاضر در یک استخر شنای سرپوشیده پرداخته شده است. نتایج حاکی از آن است که زنان در مقایسه با مردان نسبت به شرایط سرما حساس‌ترند. علاوه بر این، نتایج نشان می‌دهد که شاخص توده بدنی نیز تأثیر قابل ملاحظه‌ای بر احساس حرارتی افراد دارد. به طوری که افراد لاغر در مقایسه با افراد دارای سلامت وزنی احساس حرارتی سردتر و افراد دارای اضافه وزن دارای احساس گرم‌تر هستند. بر اساس نتایج به دست آمده، با تغییر شاخص توده بدنی افراد، شاخص احساس حرارتی افراد می‌تواند تا نزدیک به 0/4واحد تغییر کند که این امر در ارزیابی آسایش حرارتی بسیار قابل توجه است.

چکیده [English]

In the indoor swimming pools, due to the presence of people with different individual characteristics, it is important to design an air conditioning system which can provide thermal comfort conditions for the occupants. Since the differences in the persons’ individual parameters such as gender and body composition, it is required to study the effect of these parameters on the thermal comfort in swimming pools. On the other hand, the location of the air inlet diffuser is one of the effective factors affecting the thermal comfort conditions. In this study, by using the individual 3-node thermal comfort model, the effect of individual parameters on the thermal sensation of people in an indoor swimming pool has been evaluated. The results show that women are more sensitive than men to the cold conditions. In addition, it can be seen that BMI has a significant impact on people thermal sensation. So, thin people are colder thermal sensation than those with healthy physical fitness, and overweight people have a warmer sensation. Based on the results, with the change in body mass index, the index of the thermal sensation can change up to 0.4 units. This is very important in the evaluation of thermal comfort.
