【 摘 要 】

A kind of desiccant wheel with CO2heat pump is proposed. The main features of this proposed system include: (1) there are two optional ways of desiccant dehumidification and cooling dehumidification; (2) for the subsystem of desiccant dehumidification process, the air regeneration process occurs inside a closed loop, and a CO2heat pump is utilized inside this loop for air regeneration, which has the potential to significantly reduce energy consumption compared to a traditional regeneration process. The operating performance of the system is simulated and analysed. Compared to the traditional vapor compression air conditioning system, the hybrid system can save approximately 50% to 90% of energy.
