| Abstract: | The traditional solar refrigeration technologies have been classified and discussed in this paper. Their dynamical disadvantages have been put forward. A new refrigeration model is presented. A heat system collecting focus sunlight with fiber-optic min-dish is introduced and its performance is primarily evaluated. It is indicated that driving meantime both gas turbine to produce electricity for refrigeration and two-stage absorption refrigerator, which realize the gradient utilization of solar energy, is a new method to obtain high-efficient solar cooling. Primary theoretical calculation of this system has been carried out. Its net COP of 1.4 is close to that of refrigeration with electricity generated by combustion oil. |
