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...
In this research, the thermodynamic investigation of the tri-generation system is performed by the first and second law of Thermodynamics. The trigeneration system under study consists of three subsystems including the solar subsystem, Kalina subsystem and lithium bromide-water absorption chiller subsystem. The proposed system generates power, cooling and hot water using solar energy. The syste...
Saving energy is one of the most important challenges of todaychr('39')s world. Reducing electrical energy consumption in compressed air systems is one of the essential requirements for designing these systems. When using domestic air conditioners (dual air conditioners) in very hot areas (Khuzestan) their performance decreases and electric current consumption increases. Therefore, the use of n...
A methodology for assessing solar cooling technologies is proposed. The method takes into account location specific boundary conditions such as the cooling demand time series, solar resource availability, climatic conditions, component cost and component performance characteristics. This methodology evaluates the techno-economic performance of the solar collector/chiller system. We demonstrate ...
[1] The aerosol direct solar effect under clear sky is assessed by (1) combining multiple aerosol characterizations and (2) using the satellite-retrieved land surface albedo. The aerosol characterization is made through an integration of the MODerate resolution Imaging Spectroradiometer (MODIS) retrievals and the Georgia Tech/Goddard Global Ozone Chemistry Aerosol Radiation and Transport (GOCAR...
many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of suc...
