Abstract

Solution absorption energy storage is a new energy storage and release technology characterized by high energy storage density

low heat loss

good mobility

and long-term energy storage. Energy storage density and energy storage efficiency are the key indexes for measuring the energy storage capacity of absorption energy storage systems and the key parameters for evaluating the energy conversion efficiency of absorption energy storage systems

respectively. Based on thermodynamic principles

the energy storage characteristics and applicability of absorption energy storage systems were investigated using six types of absorption solutions under different conditions. The results show that both energy storage density and energy storage efficiency increase with an increase in heat source tempera

ture and cooling water temperature and decrease with solution concentration. At a heat source temperature of 70-120 ℃ and condensing temperature of 24-36 ℃

NaOH-H

O has the largest energy storage density and efficiency

CaCl

-H

O has the smallest energy storage density and efficiency

and LiBr-H

O has the widest applicability of temperature range.
