1, the rated air volume of low static pressure unit is the value when the residual pressure outside the unit is 0Pa, and the residual pressure without tuyere and filter is 12Pa. ?
2. Refrigeration operation parameters: air-drying bulb temperature 27℃, wet bulb temperature 19.5℃, water inlet temperature 7℃, and water temperature difference 5℃.
3. Heating condition parameters: inlet dry bulb temperature 2 1℃, inlet water temperature 60℃, and hot water flow rate is the same as that of refrigeration condition.
Fan coil units can be divided into vertical, horizontal, wall-mounted and card-type units. And vertical is divided into column type and low type; According to the installation method, it can be divided into surface installation and concealed installation; According to the air intake direction, it is divided into left type and right type.
Matters needing attention
