Only the tube sheet calculation for some pipe-and-tube heat exchangers
Thread Content
As the title suggests, in many heat exchangers used in air conditioning systems, the piping arrangement is irregular, or it is only partial – sometimes there is piping in only half of the area. How should the tube sheet be checked in such cases?
If no calculation method can be found, the tube sheet may be calculated as a flat head.
Take the maximum value for gb151
Is there no more specific answer? Reference standards and calculation methods, calculation process!
Most of the evaporators and condensers on air conditioners have partially distributed pipes. There is a calculation method specified in the refrigeration standards; just follow those standards for the calculation. It seems that the diameter is limited to 600 or less; for diameters exceeding this limit, GB151 applies. However, GB151 does not cover the calculation for such piping arrangements, so it’s likely that for diameters that exceed the limit, separate calculations will be necessary
