Optimization of Solar Collector and Heat Storage Tank for Solar Absorption Refrigeration

Abstract

Taking the solar hot water circulation process in absorption refrigeration as the research object, two temperature control strategies are proposed according to the operating temperature range of working pairs in the generator, and the model of solar hot water circulation is built. The tilt and azimuth of solar collector are optimized according to the maximum radiation amount per unit area of collector with Hooke-Jeeves algorithm. The area of collector is optimized according to the solar fraction specification value with 0.5. The volume of the heat storage tank is optimized according to the maximum solar fraction and minimum start stop times of generator circulating pump. The optimization method proposed can guide the design of solar hot water circulation system for solar absorption refrigeration.
