摘要
供暖型风机盘管由贯流式风机及U形肋片管构成,其散热性能与传统风机盘管有很大不同。以供暖型风机盘管在进水口热水温度为45～60℃及热水流量为30～110kg/h时不同供热工况下的散热量为基础条件,探讨了设备在定流量及变流量运行时供暖型风机盘管的散热量计算方法。
The heating-only fan coil unit,which consists of cross-flow fan and U-type coils,is different from the traditional fan coil unit in heat release performance.On the conditions that the heat release when the supply water temperature is from 45 to 60 ℃ and the water flow rate from 30 to 110 kg/h,discusses the heat release calculation method when the water flow rate is constant or variable.
