Quality for Solar Cooling on Component Level

application of upfc based on svpwm for power quality improvement

در سالهای اخیر،اختلالات کیفیت توان مهمترین موضوع می باشد که محققان زیادی را برای پیدا کردن راه حلی برای حل آن علاقه مند ساخته است.امروزه کیفیت توان در سیستم قدرت برای مراکز صنعتی،تجاری وکاربردهای بیمارستانی مسئله مهمی می باشد.مشکل ولتاژمثل شرایط افت ولتاژواضافه جریان ناشی از اتصال کوتاه مدار یا وقوع خطا در سیستم بیشتر مورد توجه می باشد. برای مطالعه افت ولتاژ واضافه جریان،محققان زیادی کار کرده ...

Solar Cooling Technology Review

This paper provides a brief summary of current solar cooling technologies based on a literature review of 16 journal articles. The REDD facility at DRI currently uses two methods of cooling: an absorption chiller driven by solar thermal, and an evaporative cooler which can be run off of solar photovoltaic. This literature search is to identify what are the best technologies to convert solar ene...

Ejector Solar Cooling

In recent times, there has been a rise in popularity of comfort cooling systems, mainly based on electrically driven heat pumps. The accompanying peak loading on electricity grids is proving to be particularly problematic and expensive for electricity utilities, notwithstanding the greenhouse gas emissions associated with the electricity consumption of these het pumps. An alternative is to gene...

Solar Heating and Cooling for Residential Applications

Radiative cooling of solar cells

Standard solar cells heat up under sunlight. The resulting increased temperature of the solar cell has adverse consequences on both its efficiency and its reliability. We introduce a general approach to radiatively lower the operating temperature of a solar cell through sky access, while maintaining its solar absorption. We first present an ideal scheme for the radiative cooling of solar cells....
