decoupling is also applied to the situation where the primary cycle is driven by a wall-mounted gas furnace water pump, and each branch of the secondary cycle water distributor is equipped with an independent small circulating water pump to strengthen the branch circulation, as shown in the figure below:
Each circulating water pump on the branch after the secondary circulation water distributor may adjust the flow rate according to the usage requirements. In order to ensure that the flow change of a certain path will not couple to other branches, or even to the primary circulation side. When the flow rate changes, a decoupling tank is needed to adjust the flow rate. In this process, the decoupling tank plays the role of decoupling, water mixing, and hydraulic balance.
In some larger-scale residential areas or campus heating systems, the primary heating cycle is circulating hot water provided by the regional boiler room. The primary cycle is based on the water pump in the boiler room. The secondary cycle needs to supply multiple individual buildings. Specifically, See the settings below:
Set up multiple water supply and return branch pipes with their own water pumps on the right side of the decoupling tank to supply multiple individual buildings. When the heating demand in a certain building changes, you can use this branch to A circulating water pump is used to adjust the flow of this branch. The changes in the flow of this branch can be coordinated through the decoupling tank to avoid coupling to other branches and thus affecting the heating effect of other units. In this process, the decoupling tank also It has the function of decoupling, mixing water, and hydraulic balance.
