What would happen if you coupled an organic rankine cycle with an absorption heat transformer?

Coupling an Absorption Heat Transformer (AHT) with an Organic Rankine Cycle (ORC) can indeed improve the overall thermal efficiency of the system. Here's a basic rundown of how it might work: 1. The Organic Rankine Cycle uses a high-boiling-point organic fluid to convert heat, often waste heat, into mechanical energy (and subsequently electricity). 2. Following the ORC process, there will still be a great deal of residual, or 'exhaust,' heat. Rather than wasting this heat, it can be used as input for the Absorption Heat Transformer. 3. The AHT is a heat pump that can upgrade the temperature of waste heat to a higher, useful temperature level. It utilizes a working fluid and a refrigerant, wherein the warm refrigerant is absorbed by the working fluid, resulting in an exothermic reaction and producing useful heat at a higher temperature. 4. This upgraded heat can then be used for various industrial processes or central heating. So essentially, by coupling an ORC with an AHT, you're repurposing the ORC's waste heat in an efficient way to create more useful energy. This method can significantly increase the overall efficiency of your system and reduce the environmental impact due to better utilization of waste heat. However, it's essential to note that actual results can vary based on many factors like the performance characteristics of the chosen ORC and AHT, the specific conditions of the heat resources and heat demand, etc. Always consult with temperature/power engineering professionals when designing an integrated system like this.
