N2 - In hot and humid climates, dampness in buildings leads to significant microbial pollution and building damage. In order to alleviate this problem, a desiccant cooling system was suggested as a suitable system to improve indoor air quality (IAQ) based on its superior humidity control. However, such systems have lower energy efficiency, so their combined use with a solar hot water/air supply system or a cogeneration system is common to improve energy efficiency. In this paper, the authors studied the possibilities and methods of combining a desiccant cooling system with a CO2 heat pump to improve overall energy efficiency and provide a steady heat source. The authors also studied the adaptability of the system under a midsummer climate and evaluated the performance of thermal comfort, IAQ, and energy efficiency using the experimental and performance data of the CO2 heat pump.
