Collision of different design concepts in HVAC hydraulic balance

Starting from the design concept of air conditioning chilled water system, combining with the experience of energy-saving reformation of air conditioning chilled water systems, analyses the differences between the two different design concepts of “dredging” and “blocking” in HVAC hydraulic balance. Puts forward the reflection and discussion on the design concept of HVAC hydraulic balance to improve the operation quality and reduce the energy consumption of air conditioning water systems. Points out the issues faced by the cooling capacity active regulation technology of ends.
