膨胀罐在壁挂炉采暖系统中的应用

Expansion tank in the wall-hung boilers Heating System

本文主要论述不同容量、不同预充压力的闭式膨胀罐在壁挂炉采暖系统中的应用。通过计算,证明在大部分的壁挂炉采暖系统中,7L容量、0.2MPa(绝对压力)预充压力的闭式膨胀罐已经足够满足系统要求。因为水容量较大,钢制柱式散热器或者铸铁散热器不宜在壁挂炉采暖系统中大量采用。

This paper discusses the different capacities,different pre-lnflatable pressure, closed expansion tank, in wall-hung boilers heating system applications. By calculating, to prove that most of the wall-hung boilers heating system, 7-liter capacity,O.2 MPa （absolute pressure ） pre-lnflatable pressure, closed expansion tank is sul^wient to meet ~the system requirements. Because of the large water capacity, steel or castiron heatsink should not be widely used in the wall-hung boilers heating systems.
