摘　　要：以天津某一高层住宅太阳能热水工程为研究对象,计算分析了容积换热式集中-分散太阳能热水系统的系统热损,结果得出可能存在的最大系统热损率为41.25%,最小系统热损率为29.82%;并指出容积式换热器的容积大小是影响此类太阳能热水系统热损率的主要因素。Taking an high-rise residential solar water system engineering in Tianjin as research object, the system heat loss of centralized-individual solar water system with displacement heat exchanger was studied. The result shows that probably the largest system heat loss rate is 41.25% and the minimum system heat loss rate is 29.82%. It also points out that the volume of displacement heat exchanger is the major influence factor of the system heat loss rate.
