As distribution in air conditioning and heating system, the energy of the water cycle system of hydraulic balance is very important. A balance of hydraulic system is to meet user requirements, the basis of energy saving. In the air conditioning and heating system, cold ( Hot) Media distribution to each user by closed pipeline system. For a well-designed piping systems, each user in the end of the control valve ( Electric control valve, temperature control valve, etc. ) Opening of 100% should be to get the design of water, and at the end of each user control valve opening change when can get the required flow and mutual interference. The water system is a hydraulic balance system, otherwise it is unbalanced hydraulic system, hydraulic imbalance is also called the hydraulic imbalance. Hydraulic disorder generally fall into two kinds of static imbalance and dynamic disorder. The so-called static disorder is also known as steady disorder. The system, each user under design condition, actual traffic does not accord with the design discharge. This kind of hydraulic imbalance is fundamental, if not solved, always there. For constant flow system, the disorder can use static balancing valve or to solve the dynamic balance Industrial Valves, the difference is that the former need adjusted instrument, while the latter does not need to. Dynamic disorder is also known as stability disorder. The system, the change of chilled water when some users ( Closed or adjust) , will cause the resistance distribution of system changes, resulting in the flow of other users with the change. The hydraulic imbalance is random and dynamic change. Static balancing valve cannot solve the disorder phenomenon, can only be solved using dynamic balancing Industrial Valves. For example: a building of six storeys, such as the dynamic flow balance valve not installed, the water system in the actual operation of dynamic imbalance. In air conditioning cooling season, 1 ~ 2 room is too cold, 3 ~ 4 layers just reached design comfortable room temperature, 5 ~ 6 layer room is too hot. On the other hand, during the heating season, the first to second floor room will be too hot, 3 ~ 4 layers just reached design comfortable room temperature, 5 ~ 6 layer room is too cold. After the installation of dynamic flow balance valve, whether using a ~ 6 layer room all or only part in air conditioning room, all rooms can meet the design temperature.
