Summary

Developing efficient and energy-saving air-conditioning systems is important for achieving energy conservation and emission reduction. Herein, we propose a novel temperature and humidity independent control system based on dual cooling sources (DCS-THIC) of refrigerant and cooling water, which introduces cooling water to drive the desiccant adsorption and recover the condensation heat for desiccant regeneration. A uniform framework based on thermodynamic principles is built to analyze the overall performance of the new system and discuss the parameter influences. Modeling results show that the DCS-THIC system is most efficient under hot and humid climates. And the energy consumption of the DCS-THIC system increases with increasing room sensible heat ratio (RSHR) and decreasing supply air temperature difference. In addition, it is revealed that metal-organic frameworks are the most suitable sorbents for the new system. This study proves the feasibility and applicability of the novel DCS-THIC system for realizing high-performance dehumidification and cooling.
