Byanlyzing the effect of hydraulic misadjustment an d temperature drop of water supplied on thermodynamic imbalance,two feasible op t ions in designing outdoor heating networks:It is iuggeeted that the same distanc e system of heating and the mixing system of heating are proposed.

The thermodynamic imbalance phenomenon caused by hydraulic imbalance as well as caused by heating quality regulating is studied.

Comprehensive and optimizational regularization of hydraulic stepout in the boiler system;

The solving method of hydraulic stepout in water system of air conditioning;

In this article according to hydraulic stepout and difficult balancing regulation phenomena in outdoor heat supply network a economic and practical regulation method is introduced for hydraulic balancing based upon formula derivation, which realize the proper distribution of discharges between customers and provide guaranteed foundations for heating quality and energy saving.

Analysis on hydraulic disorder of indoor two-pipe reverse-return heating systems with household metering;

Analyses on the hydraulic disorder problems in central heating system for single-storey houses(particularily for reverse return system),and puts forward the direction and measures to solve these problems.

Analyses the causes of hydraulic disorder in heating network and the technology of using hydraulic balance equipment to resolve hydraulic disorder problem,discusses the energy saving of multistage pump systems,and gives recommendations for using multistage pump systems.
