Scope
This part of GB/T 27698 specifies the test methods for heat transfer and fluid resistance performance of spiral plate heat exchangers under test conditions of liquid-liquid non-phase change, vapor-liquid condensation with phase change, and vapor-liquid evaporation with phase change. This part is applicable to test fluids of liquid-liquid and steam-liquid. This part only considers the thermal conduction resistance of the heat transfer plate material, and does not consider the fouling resistance on both sides of the heat transfer plate.
