Abstract：
Presents the way of using specific enthalpy as the data collecting unit for heat exchange device information engineering. Taking the cooling tower as an example, analyses the relationships of the specific enthalpy collection error and the measurement errors from physical sensors. Reveals the selection bases of physical sensors and gives the design rules of the specific enthalpy collection system.
