摘要 阐述了基于温湿度独立控制的水蓄冷空调系统（CWS-ITHC）的工作原理、特点和设计方法。案例分析结果表明，该系统除具备温湿度独立控制系统的优点外，还具有减小设备容量、节省系统初投资，蓄冷密度（温差）大、大幅度减小蓄冷槽体积，利用夜间低价电力蓄冷、大幅减少运行费用等特点。 关键词 温湿度独立控制 水蓄冷　独立新风系统 设计方法 Chilled water storage air conditioning system with independent temperature-humidity control By Yan Chengchu, Liu Yanhua and Shi Wenxing Abstract Explains the working principle and characteristics of the chilled water storage air conditioning system with independent temperature-humidity control(CWS-ITHC) and its design method. A case study shows that besides the basic advantages of the independent temperature-humidity control system, the system is featured reduced necessary chiller capacity to economize the initial investment，significantly decreased reservoir volume for its high cold storage density, and significantly lowered operational expenses by producing and storing the cold thermal energy with discounted power price during nighttime.
