How much is the number of copper tubes needed to install the central air conditioner?
Central air conditioning refrigerant pipe does not need to calculate the number of pipe diameter, the factory equipment, the receiver has limited the size of the pipe. Wind system only need to calculate the diameter of the pipe.The wind system is the assumption that the flow velocity range according to GB standards, to assume a wind speed of V, and then through the air as is known, then according to the wind pipe area (3600* = air / wind duct area that is assumed), and then to check the information, the wind pipe what size can be selected, 0.23 is that before the wind area, then you can choose a 500*500 wind pipe, this pipe is 0.25 of the area, then put 0.25 into the formula: = air / wind speed (wind area *3600), namely: V= / air (0.25*3600), can be calculated by 500*500 tube after wind velocity.Finally, the pipe diameter is the diameter of the preliminary design under the premise that the actual flow rate meets the specifications. Of course, the calculation needs to be checked later.
If there are CAD drawings would be well determined first indoor machine tool position and then pull it but not straight along the walls should pay attention to
Draw the drawings, mark the pipe diameter, measure the length and multiply the loss factor
The central air conditioner copper tube needs to calculate the length. Look what type you install. If it is multi - line, multi - tube, you should calculate the distance between each indoor unit and outdoor unit. If you are online with a manifold, you should also calculate the distance between the interior and the interior. Hope to answer some of your help.
