Summary

Currently, energy-efficient air-conditioning equipment is required to realize an energy-efficient society. Ventilation and appropriate dehumidification are necessary for the living environment. Therefore, focus is placed on liquid-desiccant air-conditioning systems. In this study, the control of a liquid desiccant air-conditioning system is performed under actual weather conditions using a feedback control system to evaluate the energy-saving performance and response of absolute humidity of the supply air, which is the control quantity, toward energy saving. This study aims to gain knowledge for establishing a control method. For the case when humidity is high throughout the entire day, the absolute humidity of the supply air can be controlled within ±0.05 g/kg(DA) most of the time, regardless of whether the manipulated variable is hot water temperature or the air flow rate on the regenerator side.
