中文摘要：
吸收式蓄能技术具有蓄能密度高、热损失小等特点，是一种具有发展潜力的蓄能技术，但目前的技术尚存在吸收效果差、效率不高等问题。提出基于增压吸收的吸收式蓄能方法，并阐述其装置的工作原理和特点，通过数学模型研究在不同工况下增压对其热力学性能的影响规律。结果表明：当蒸发温度与发生温度越低、冷凝温度越高时，增压器改善吸收式蓄能循环的性能系数（COP）越明显；与无增压吸收式蓄能循环相比，蓄能密度（ESD）得到提高，当增压比为3时，其ESD可提高30%～295%。
英文摘要：
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.
