Scope: This part of GB/T27698 specifies the liquid-liquid non-phase change and vapor-liquid condensation phase change of heat transfer tubes for shell-and-tube heat exchangers, plate heat exchangers, spiral plate heat exchangers, and shell-and-tube heat exchangers. 1. A general method for performance testing of vapor-liquid evaporation with phase change test conditions. The test fluids applicable to this section are liquid-liquid and vapor-liquid. This section only considers the heat conduction thermal resistance of the heat transfer plate (tube) material, and does not consider the thermal resistance of dirt inside and outside the heat transfer plate (tube).
