Study of heat release calculation method of heating-only fan coil unit

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.
