Problem description
最小压降 across the 阀门 component is helpful, in the case of valves installed near or on terminal units, in obtaining the required authority; in addition, for some valve types (e.g. Δp控制器) manufacturers recommend a specific value of Δp最小. For the calculation, the value is taken from the valve data table and can be changed individually there. Problems related to the program's inability to achieve the set Δp最小 are identified by the message:
不能确定阀门上的最小压降ΔP最小
The above message appears when:
- 阀门 has no settings (has a specified kv值 value) and has no thermostatic head,
- for the smallest setting the flow through the 阀门 does not produce the required pressure drop.
Solution
In most cases, the diagnostic message 不能确定阀门上的最小压降ΔP最小 can be left without responding to it. In the case of a mass occurrence of the message for the 阀门 component on/near the terminal units, and therefore when there is a concern of obtaining too low authorities, the following can be done:
- use, if available, valves or integrated valves with a lower kv值 range,
- increase the flow rate through the terminal units in question by reducing their calculated temperature drop. However, the final cool down value in the terminal unit is determined by the 调节流量 option, which is enabled by default in the 一般参数, 散热器计算选项 window..
