英文摘要：

The hybrid refrigeration cycle powered by combined electricity-solar energy is presented for the shortcomings of conventional solar-driven absorption refrigeration cycle, such as low efficiency, intermittent operation and high cost. The novel cycle can achieve all-weather operation by the coupling of air-cooled and water-cooled compression refrigeration units, and obtain high thermal performance and mechanical performance. The thermodynamic model of each component is established to analyze the effects of hourly solar irradiance and the outdoor air temperature on the COP of absorption refrigeration unit, air-cooled compression refrigeration unit and water-cooled compression refrigeration unit. The energy consumption of hybrid cycle is compared with that of conventional air-cooled compression refrigeration cycle. Main conclusions are reached.
