Performance Analysis of Isopropanol-Acetone-Hydrogen Chemical Heat Pump
Keywords:IAH CHP, COP, exergy, temperature, flow rate.
This paper presents an experimental system of isopropanol-acetone-hydrogen chemical heat pump (IAH CHP) for the recovery of low-grade (<100oC) industrial waste heat. Using coefficient of performance (COP) and exergy efficiency as evaluation indices, the system performance is systematically evaluated based on the experimental data. The performance of the IAH CHP is found to be greatly affected by the endothermic and exothermic temperatures, and the flow rates of working fluid. The system performance reaches the optimum at about 360 K and 1.40 ml/s in the actual experimental system. And good heat insulation can reduce the heat loss and energy consumption.
