Therefore, in a constant flow air conditioning system, the flow demand value of each terminal device can usually be calculated, and the static balancing valve can be set to distribute the total system flow on demand so that the flow at each terminal reaches the design value. However, the flow demand value at the terminal is adjusted according to the difference between the indoor temperature and the set value. When the usage time, temperature setting and usage of each end change, the terminal flow demand will show a dynamic change value.
