Do buildings generally use the same program or different programs?

The same procedure. In the same program system, the total pipe length of each parallel loop is equal, and the water resistance of each user coil is equal. The system has good hydraulic stability and even flow distribution, and is more convenient to use in buildings. The pipeline of different program system is simple, and there is no need to use the same process pipeline, so the investment of water system is small, but the water distribution and adjustment are difficult.
