Dynamic flow balance valve performance

 In the air-conditioning and heating system, water system, as energy transmission and distribution of water balance is very important. A balanced hydraulic system is to meet user needs, saving energy consumption basis.

     In the air-conditioning and heating systems, cold (hot)-borne transmission and distribution pipeline system from the closed to the consumers. For a well-designed systems, and all users at the end valve (electronic control valve, temperature control valve, etc.) is 100% opening should have access to the design of water, while the various users at the end of the opening control valve to change the when you can get the required flow again without disturbing each other. This water system is a hydraulic balancing system, otherwise unbalanced hydraulic systems, hydraulic imbalance also known as hydraulic imbalance.

     Hydraulic imbalance is generally divided into two kinds of static imbalance and dynamic imbalance. The so-called static disorder, also known as steady-state offset. The system, each user in the design of state, does not match the actual flow and design flow. This hydraulic imbalance is fundamental, if not addressed, the impact will remain. For constant flow systems, this imbalance can be static or dynamic balance valve balancing valve to solve, the difference is that the former need to use instruments to regulate, while the latter do not need to. The so-called dynamic disorder also known as the stability of the disorder. The system, some users of the water flow when the change (closed or adjustable), the resistance distribution will cause the system to change, leading to the flow of other users with the changes. This imbalance is random changes in hydraulic and dynamic. Static balance valve can not resolve this imbalance can only be resolved using dynamic balancing valve.

     For example: for the six floors of a building, without installation of dynamic flow balance valve, then the water system in actual operation, dynamically disorders. In the air-conditioning cooling season, the first ~ second floor of the room would be too cold, three ~ four comfortable rooms just to meet the design temperature of 5 ~ six layers of the room is too hot. On the contrary, in the heating season, the first ~ second floor of the room would be too hot, the three ~ four comfortable rooms just to meet the design temperature of 5 ~ six layers of the room is too cold. After the installation of dynamic flow balance valve, whether it is a ~ six-room all to use, or only some of the rooms in the use of air-conditioned, all rooms can meet the design temperature.
