چکیده

هدف از این مقاله، مقایسه عملکرد الکتریکی و حرارتی طرح‌های مختلفی از کلکتور ترکیبی فتوولتائیک – حرارتی است. مزیت مهم کلکتورهای فتوولتائیک - حرارتی نسبت به مدول‌های فتوولتائیک مرسوم، کاهش دمای مدول و افزایش راندمان تولید الکتریسیته آن است. از طرفی استفاده از این روش منجر به تولید حرارت و الکتریسیته در یک دستگاه و در نتیجه کاهش سطح مورد نیاز برای نصب کلکتور و مدول می‌شود. در تحقیق حاضر راندمان الکتریکی و حرارتی چند طرح متفاوت از یک کلکتور ترکیبی فتوولتائیک - حرارتی که از آب برای خنک کردن آن استفاده شده مورد بررسی قرار گرفته است. به منظور بررسی و تعیین اثرات پارامترهای هندسی بر عملکرد کلکتور فتوولتائیک - حرارتی، مدل‌سازی حرارتی مدول فتوولتائیک و هشت طرح متفاوت از کلکتور ترکیبی فتوولتائیک - حرارتی نوع ورق و لوله با طرح‌های لوله مارپیچی (مقطع گرد) و لوله موازی (مقاطع گرد، مربعی و مستطیلی) به صورت تئوری و به کمک نرم‌افزار متلب انجام شده است. بر طبق نتایج به دست آمده از این تحقیق، طرح ورق و لوله با مقطع گرد کمترین و مقطع مستطیلی دارای بیشترین راندمان حرارتی و کل است. همچنین وجود پوشش شیشه‌ای سبب کاهش راندمان الکتریکی و افزایش راندمان حرارتی و انرژی حرارتی کل می‌شود.

چکیده [English]

This paper aims to compare the electrical and thermal performance of different designs of hybrid photovoltaic-thermal collectors. The main advantage of photovoltaic-thermal collectors in comparison to common photovoltaic modules is decreased cell temperature and an associated increase in their electrical efficiency. In addition, the combination of photovoltaic module and solar thermal collector makes it possible to produce both heat and electricity in a single device and reduces the area required for collector and module installation. In this research, the electrical and thermal efficiency of different designs of photovoltaic-thermal collectors is investigated. The heat transfer fluid considered for heat dissipation is water. A theoretical analysis of eight types of different photovoltaic-thermal collectors, including sheet and tube with spiral (circular cross-section) and parallel tube (circular, square and rectangular cross-sections) designs were implemented based on thermal modeling. These include collectors with different flow paths and different cross-section geometries. According to the results, sheet and tube design with circular cross-section has minimum and sheet and tube design with rectangular cross-section has maximum thermal and total efficiency. Also, glass cover reduces the electrical efficiency and increases the thermal efficiency and total thermal energy.
