With energy conservation, advocating low-carbon life is becoming today's theme, green living advocate, development and utilization of solar and other clean energy, increasing attention has been paid. In summer, solar jet refrigeration system can be effective use of solar energy for refrigeration, and then cooling for the building. But by the influence of solar radiation, when cloudy day or at night, such as solar radiation conditions are bad, the system would be difficult to meet the cooling needs of the building, when solar conditions were better, solar radiation will appear margin. In order to make full use of solar energy resources, storage solar jet - compressed composite system depth experimental study. Has been transformed in the thermal analysis calculated on the basis of separate solar ejector refrigeration system test bed to increase the compression storage system and related equipment design and selection. The main research work are: (1) - a thermodynamic analysis of the compressed composite system, the analysis showed that the composite performance of the system is superior to separate solar injection system, and the individual electrical compression system, and there exists the optimal intermediate temperature range the regenerator type solar ejection When the condensation temperature of 35 ° C, the intermediate temperature range of 5 ° C to 10 ℃ system EER highest. (2) on the basis of the analysis of the heat bench design, the completion of the storage tank, the design or selection of intermediate heat exchangers, compressors and other equipment; on the the bench water system, electrical control system and measurement system the design, manufacture, or selection. Built in storage solar jet - the compressed composite system test bed. (3) for a certain working conditions for experimental research. When the system condensing temperature of 32 ° C, the intermediate temperature of 15 ° C, the evaporation temperature of -5 ° C, -10 ° C, -15 ° C, the occurrence of the temperature varies from 72 ℃ to 82 ℃ system EER and COP showed first rose high to reduce the trend, the total power consumption presented first and then decreased, the EER and COP up to 2.65 and 0.155, respectively, the optimal generation temperature range from 76 ℃ to 78 ℃; study the occurrence of temperature were 75 ℃, 80 ℃, 85 ℃, condensing temperature of 35 ° C, the intermediate temperature varies from 5 ℃ to 20 ℃, the the system EER, cooling capacity, power consumption; system energy efficiency up to 2.6 The cooling capacity of up to 1350W, the optimal intermediate temperature range from 12 ℃ to 15 ℃. The study results show that, the storage solar injection - compression composite system in the corresponding conditions of stable operation, the basic design requirements; injection - compression for storage solar the composite system occurred and intermediate temperatures there are optimal work area through the study found, In this area, the better the performance of the system, but further analysis of the operation of the compressor in the composite system, the next step for the system has laid the foundation for more in-depth study.
