摘　　要：传统空调方式将处于不同温度水平的热源所产生的热量混合入室内空气中,再对室内空气进行降温处理,这种方式忽略了室内温度场分布的不均匀特性,造成了高品位热源与低品位热源的掺混损失。基于热源独立排热和温湿度独立控制的思想,分析了理想的排热和排湿效率,并通过典型算例计算了不同形式系统的排热和排湿效率。The conventional air conditioning mode mixes all the heat from the heat sources in different temperature levels into the indoor air and cools the air,which ignores the non-uniform character of indoor temperature field and leads to the mixture lose of high temperature heat source and low temperature heat source.Based on the idea of independent cooling and temperature and humidity independent control,discusses the ideal cooling and dehumidifying efficiency,and calculates the efficiency of different systems with typical cases.

关 键 词：热源 排热效率 排湿效率 温湿度独立控制
