Abstract
In recent years, demand response has been emphasized due to the introduction of renewable energy with unstable power supply. Liquid desiccant systems have a heat storage effect, so it may be suitable for demand response, but it has not been studied. Therefore, in this research, we focused on using liquid desiccant systems as a power supply and demand adjusting regulator. We evaluated the unsteady behavior of this system by numerical simulation when it is used as a power supply and demand adjusting regulator. We created a mathematical model consisting of a gas-liquid contactor, a solution tank, and a room, and investigate the duration of power control without compromising comfort. As a result, it was clarified that a duration of about 30 minutes can be obtained by enlarging the solution tank and increasing the solution circulation amount appropriately. It was shown that the liquid desiccant air-conditioning system can be sufficiently used as a power supply and demand regulator.
