摘　　要：从最基本的热水膨胀量计算公式入手,结合目前地面辐射采暖的设计习惯,推导出符合工程实际应用的低温热水地面辐射采暖用定压膨胀水箱选型计算方法。以此在技术层面上推动膨胀水箱这一结构简单、性能可靠、价格低廉的采暖系统定压设备在地面辐射采暖中的应用。从细节上为建筑设备领域的节能减排提供一点思考。Beginning with the most fundamental calculation formula of the hot water expansion amount, it combines with the present design for the floor radiant heating, derives the selection algorithm for the constant pressure expansion tank used in low-temperature floor radi- ant heating, which corresponds with engineering practices. Based on this, it will help to promote the application of expansion tank on the floor radiant heating at the technical level, the expansion tank is the heating system constant pressure equipment with simple structure, reliable performance and low price. The study can provide some thoughts in detail for energy-soving emission reduction of building equipments.
