Abstract    The system design of window air conditioner does not evolve in one day. Due to the continous efforts are taken by the refrigeration and air conditionging professionals, successful and economic models of window air conditioners are currently used. This paper states about the development of window air conditioner with phase change material and water as refrigerants. Developed air conditioner was tested for its thermal performance achievement. Outcomes specify that thermal comfort acheivement was in satisfactory levels. Predicted mean vote and percentage of people dissatisfied values were calculated and the results were in the range of neutral to a slight cooling, according to Americal Society of Heating and Refrigeration and Air conditioning standard 55.


Keywords    Water, Phase change material, refrigerant, window air conditioner, thermal comfort, chloro fluoro carbons



طراحی سیستم تهویه هوا پنجره‌ای در یک روز تکامل نمی‌یافته است. با توجه به تلاش‌های مستمر توسط متخصصان تهویه مطبوع و تهویه مطبوع، مدل‌های موفق و اقتصادی تهویه هوا پنجره در حال حاضر استفاده می‌شود. این مقاله در مورد توسعه تهویه مطبوع پنجره با مواد تغییر فاز و آب به عنوان مبردها بیان می‌کند. تهویه مطبوع طراحی شده برای دستیابی به عملکرد حرارتی آن آزمایش شده است. نتایج حاکی از آن است که دسترسی به گرما در سطح رضایت بخش بوده است. طبق استاندارد جامعه استاندارد گرمایش و تبرید آمریکایی و استاندارد تهویه مطبوع 55، پیش‌بینی میانگین رای و درصد از ارزش‌های ناراضی مردم محاسبه شد و نتایج در محدوده خنثی به خنک‌کننده خفیف محاسبه شد.
