Application of surface cooler and its temperature control valve to air conditioning variable volume chilled water system
Dong Zhesheng
Based on the analysis of the existing research conclusions, points out that the static characteristic function between the relative cooling capacity and the relative flow rate of surface cooler and the regulating characteristic function between the relative flow rate and the opening of the temperature control valve are almost impossible to be exactly a pair of inverse functions in practical engineering, and it is difficult and unnecessary to reverse compensate the static characteristics of the surface cooler and the ideal characteristics of the temperature control valve in order to obtain the linear proportional relationship between the relative cooling capacity of the surface cooler and the opening of the temperature control valve in theory and practice. Proposes a hydraulic balance solution based on (0, hg) on-off control strategy for temperature control valve in practical engineering application.
