摘要 通过对深圳某工业厂房分别选用常规冷凝除湿空调系统和溶液除湿空调系统进行系统设计和理论计算分析，比较了两类空调系统的能耗及COP。在夏季室外设计工况下，常规冷凝除湿空调系统的COP为2.94，溶液除湿空调系统的COP为5.42。室外空气含湿量越小，对提高溶液除湿系统的性能越有利。溶液除湿空调系统在节能方面具有较大的优势。 关键词 溶液除湿 热泵 工业厂房 空调 Energy consumption analysis of liquid desiccant air conditioning system for industrial buildings By Tang Yidan and Liu Xiaohua Abstract Based on the system design and theoretical analysis of conventional air conditioning system and liquid desiccant air conditioning system for an industrial building in Shenzhen, compares the energy consumption and the COP of the two kinds of systems. The results indicate that in the outdoor design condition in summer, the COP of the conventional air conditioning system is 2.94, while that of the liquid desiccant air conditioning system is 5.42, and that the lower the humidity ratio of outdoor air is, the better the performance of liquid desiccant air conditioning system is, verifying the advantage of liquid desiccant air conditioning systems in energy saving.
