Due to its high thermal storage density and little heat loss

absorption thermal energy storage (ATES) is known as a potential thermal energy storage technology. However

current equipment has poor absorption ability and suffers from low efficiency. In this paper

a pressurized absorption thermal storage technology is proposed and the principle is introduced. Effects of pressurization on the thermodynamic performance are analyzed under different operating conditions. The results indicate that the utilization of pressurization can largely enhance the coefficient of performance of ATES system when the evaporating and generating temperatures are low and condensing temperature is high. Comparing with the absorption storage cycle without pressurization

a cycle with pressurization can increase the energy storage density by 30%-295% at the pressure ratio of 3.
