【 摘 要 】

In view of the climate characteristics of hot summer and cold winter area, a novel cascade double cooling source air-conditioning CDCS system is proposed in this paper. The system can achieve heat-humidity independent control in hot and humid summer and high efficiency heating in cold winter. In this paper, theoretical analysis and Aspen Plus simulations are carried out to study the refrigeration of the system under various operating parameters and climatic conditions, meanwhile the comparison between the proposed system and two conventional systems is performed. Results demonstrate that the refrigerating efficiency of the novel system are 52.7% and 22.7% higher than that of the conventional single-cold air-conditioning and dual-cold air-conditioning, under the optimal design parameters.
