Scope
This part of GB/T 27698 specifies the heat transfer and fluid resistance performance testing methods for heat exchange tubes used in shell-and-tube heat exchangers under the following test conditions: liquid-liquid without phase change, vapor-liquid with phase change, flow boiling evaporation with phase change, and pool boiling evaporation with phase change.
The test fluids applicable to this part are single-component or only considered as single-component liquid-liquid and vapor-liquid.
This part only considers the thermal resistance of the heat exchange tube material, and does not consider the thermal resistance of the dirt on the inner and outer sides of the heat exchange tube.
