Simulation and experiments on a solid sorption combined cooling and power system driven by the exhaust waste heat

Abstract

A solid sorption combined cooling and power system driven byexhaust waste heat is proposed, which consists of a MnCl₂ sorption bed, a CaCl₂ sorptionbed, an evaporator, a condenser, an expansion valve, and a scrollexpander, and ammonia is chosen as the working fluid. First, the theoreticalmodel of the system is established, and the partitioning calculationmethod is proposed for sorption beds. Next, the experimental systemis established, and experimental results show that the refrigeratingcapacity at the refrigerating temperature of –10°C and theresorption time of 30 min is 1.95 kW, and the shaft power is 109.2W. The system can provide approximately 60% of the power for the evaporatorfan and the condenser fan. Finally, the performance of the systemis compared with that of the solid sorption refrigeration system.The refrigerating capacity of two systems is almost the same at thesame operational condition. Therefore, the power generation processdoes not influence the refrigeration process. The exergy efficiencyof the two systems is 0.076 and 0.047, respectively. The feasibilityof the system is determined, which proves that this system is especiallysuitable for the exhaust waste heat recovery.
