Recold JT Revit File
The Revit product family for the Recold® JT cooling tower (“JT”) provides the basic geometry and typical pipe connections for each unit size of the product line. The product family is compatible with Revit version 2012 and later, and may be downloaded at /Revit.
Inlet and Outlet Connections
Depending on unit size, standard JT models have one or two inlet connections and one outlet connection per cell. Inlet and outlet piping connection(s) are standard male pipe thread (MPT). Connection size defaults to commonly used pipe diameter(s) for the unit size selected. Actual connection size and quantity may vary depending on the design flow rate, and should be confirmed in the quotation.
检修门
Depending on unit size, standard JT models are equipped with between two and nine large rectangular access doors per cell. Standard access door locations are linked to the model number in the Revit family.
多个单元格
Multiple instances of the JT product family may be inserted into the Revit project for installations having multiple cells. Arrangements with Face A (long face, fan on left) of one cell oriented towards Face C (long face, fan on right) of another cell are the most common.

间隙
除了进行基本塔维护所需的间隙外，还必须在进气口和排气口处留出适当的间隙，以确保足够的空气流动。间隙要求因应用而异，但进气口间隙可近似为一个单元宽度，排气口间隙应不小于三个单元宽度。还要注意，冷却塔周围的垂直外壳不应高于风扇排气口，否则空气再循环可能会影响性能。
