Summary

The conventional solid sorption refrigeration system could hardly utilize hot water below 90 °C as the driving heat source, and obtain a refrigerating temperature below -10 °C at a condensing temperature above 35 °C, which severely restricts its scope of application. Additionally, for vapor-compression refrigeration systems, low evaporating temperatures inevitably result in high power consumption and low coefficient of performance (COP). To solve these problems, a novel hybrid solid sorption-compression refrigeration cycle is proposed, and a compressor is added between sorption bed and condenser to control desorption pressure, allowing sorbent to regenerate at a lower heat source temperature. At a condensing temperature of 35 °C, the hybrid cycle utilizing the working pair of SrCl2NH3 can operate even at a heat source temperature of 60 °C, while for the conventional one, heat source temperature must exceed 98.6 °C. Its COP is almost independent of the evaporating temperature, mainly benefiting from the constant pressure ratio and compressor power consumption at a given heat source temperature. Furthermore, the hybrid system can effectively recover the waste heat of engine jacket water, thereby providing refrigerating capacity for refrigerated trucks. Under the conditions of 50 °C condensing temperature and -25 °C evaporating temperature, its COP is up to 5.0, while the value of conventional system is only 1.3. Moreover, the hybrid system can utilize 60–90 °C solar hot water to provide refrigerating capacity for refrigerated warehouses. Ultimately, the novel hybrid cycle not only effectively extends the application range of the solid sorption cycle, but also features a higher COP compared to the vapor-compression one.
