Résumé

The overall objective of this paper is to introduce the novel concept of cooling with solar cogeneration. Solar cogeneration is the combined production of photovoltaic electricity and heat. The ability of solar cogeneration to produce both controlled temperature hot water and electricity provides a flexible platform for solar cooling, addressing a customer’s need for heat in the winter, cooling in the summer, and electricity year-round. Solar cogeneration is ideal for use with either adsorption or single effect absorption chillers. Both single effect absorption and adsorption chillers utilize driving temperatures below 210F. At these temperatures, the hot water heat source can be stored in insulated, low pressure tanks at relatively low cost. This low cost storage allows the cooling system to address customer demand profiles and demand charges beyond the solar resource. Operating at temperatures below 212 F also improves the overall system efficiency. The dual energy streams of electricity and heat provide the highest solar cooling system performance.
