水平串采暖系统,广泛用于住宅、办公楼、商店、体育馆,以及农村建筑。水平串采暖系统有许多优点:管材用量少,无热力和水力失调、可逐层施工、安装简单、工业化程度高。水平串采暖系统的运行缺点,是与排气方法有关系的。大多数情况,需要通过每个散热器上的排气阀来实现排气(图l,α),这就给采暖系统在使用上带来麻烦。试图使 Horizontal string heating systems are widely used in residential buildings, office buildings, shops, gymnasiums, and rural buildings. The horizontal string heating system has many advantages: less piping, no heat and hydraulic imbalance, layer-by-layer construction, simple installation, and high degree of industrialization. The operating shortcomings of the horizontal string heating system are related to the exhaust method. In most cases, it is necessary to achieve the exhaust through the exhaust valve on each radiator (Fig. 1, a), which causes troubles in the use of the heating system. Trying to make
