1Use of energy by moving object
If an absorption machine is coupled with a heat pump to improve energy efficiency, then energy efficiency is improved, but the system complexity increases
Solution Approach 1:
The patent merges the absorption machine and heat pump into a single integrated thermal system where components are shared. The condenser and absorber of the absorption machine serve dual functions as both heat rejection devices and evaporators for the heat pump, eliminating the need for separate components and reducing overall system complexity while improving energy efficiency.
Solution Approach 2:
The condenser and absorber components perform multiple functions: they act as heat rejection devices for the absorption machine and simultaneously serve as evaporators for the heat pump. This multi-functionality reduces the total number of components needed while enhancing the overall energy efficiency of the system.
